OPERATION MANUAL
CARDY® Pet:PC-based ECG diagnostic system, version 1.3.0.*
Introduction
Your CARDY® PET intelligent ECG system provides a double way of usage:
- when connecting to a PC, it carries out traditional, laboratory ECG tasks: measurement, analysis, data storing, comparing, printing out of findings
- without PC, it operates as usual stand-alone ECG equipment: measures and analyses ECG
1. Functions of the Cardy system
As a stand-alone equipment:
- Monitoring of 6 limb leads and 2 chest leads
- Storage: raw or processed curves
Connected to PC:
- Monitoring of 6 limb leads and 2 chest leads
- Storage of patients’ data and ECG records on hard drive in compressed form. (On hard drive of 20 Gbyte 1.7 million ECG can be stored)
- Automatic parameter computation and classification
- Visual comparison of ECG measured on different time
- Editing and storage of comment to ECG record by built-in editor
- Printing of findings
- Archiving and recovering data base
- Export and import function for data exchange
- Built-in e-mail sending of ECG record
- Local network supporting
- Easy-to integrate to praxis software (option: uses GDT standard)
- Windows 2000, XP, Vista compatible
1.2 Elements of the system:
- Cardy ECG unit
- PC, infra-cable, software
- Patient cable, electrodes
- Cardy holder (option)
Minimal requirements:
- Pentium CPU, 64MB RAM
- SVGA Monitor, 1 GB HDD
1.3 General requirements
Before starting read this manual carefully. The manufacturer can only be held responsibility for the safety, reliability, and performance of the apparatus, if:
- The electrical installation of the relevant room complies with IEC requirements
- The Cardy is used in accordance with the operating instruction
1.4. Location
Do not keep or operate the apparatus in a wet, moist or dusty environment. Also, avoid exposure to direct sunlight or heat from other sources. Do not allow the unit to come into contact with acidic vapors or liquids, as such contact cause irreparable damage.
The unit should not be placed near X-ray or diathermy units, large transformer or motors. In same cases the switching power supply unit of notebooks and displays can cause 50Hz noise on ECG signal. If it happens, ask assistance from experts.
The Cardy is battery operated, use always 2 pieces of AA type alkaline batteries or compatible accumulators. Take care of polarity when changing the batteries.
Usage of any kind of power supply is dangerous and prohibited.
The patient’s pacemaker or other stimulator can be simultaneously used with Cardy, the do not interfere each other. However the doctor must know the presence of these equipments and he/she should evaluate the ECG in the awareness of this.
The Cardy can not be applied to ECG leads measured directly on the surface of the heart.
1.5. Usage of defibrillator
1.5.1 The input of the Cardy is not protected against defibrillator spike, so during defibrillation the patient cable should be pulled from the Cardy or defibrillation-protected patient cable should be used.
During measurement the patient’s bed, the patient him/herself, and the equipment applied on patient should not be touched as this can lead to injury.
Avoid touching the Cardy, patient or patient cable during measurement, as it can cause noisy ECG.
1.6. A Cardy can not be used during applying high-frequency surgical equipment.
1.7. Before operation
Check if the system is in proper condition with special regard to the connection of the patient cable
Polarization voltage and due to it base line wandering may occur if old and new electrodes are used simultaneously. The same can happen if disposable electrodes are used together with non-disposable electrodes.
1.8. During operation
If the safety of the patient requires, switch off the system or remove the electrodes.
Do not touch the electrodes and the patient. Do not let the patient or the electrodes contact electrically leading units such as metal parts of examining bed, metal stand etc.
During measurement the patient should locate at least 2-3 m from transformer (TV, PC, mobile phone) as these can disturb the measurement.
Special attention should be taken on power supply unit of the notebooks: if the ECG is comprises noise try to pull out the power supply unit from the mains.
1.9. After operation
Detach the electrodes first. The PC must be switched off only if the system will not be used for a longer period of time (some hours)
Clean the non-disposable electrodes after every examination. Use alcohol or other special electrode cleaning liquid for this.
1.10. Maintenance and checking
The system and accessories should be checked regularly by authorized people.

CARDY® PET PC ECG:
A routine measurement is carried out as follows:
Visualization of 6 limb leads and 2 chest leads on PC display
- Switch on CARDY by pressing the O key. Put the infrared connector in front of the upper IR window of the device. A “ PC USER” message on Cardy LCD will appear. If you want to make a PC measurement, just go to the next step (Run the PC program)
“PC USER” is a special “patient” as no unintentional storage of ECG in Cardy is allowed. If some other user name is seen, ”PC USER” is automatically set by PC, when visualization is started on PC display. If you want to store ECG in Cardy as well, select other user in Cardy” with the ê or é key, and accept it by ü key. Store ECG in Cardy by answering ü for “Save ECG” question after analysis.
- Run the PC program using the “Cardy” icon.
- Check the PC – Cardy connection (“Cardy3 Pet ONLINE” is displayed on the middle bottom line on your PC screen.) If “Cardy offline” is displayed, check Cardy and the infrared connection.
- Record the new patient by clicking the “empty page” icon. Type in the owner’s name and name - this fields are obligatory, the other fields are optional. The Case History is displayed on each ECG records.
Alternatively, select an existing patient from the list. The heart icon turns red (active.)
- Enter the monitoring window by clicking on the Heart icon:
- Set the leads to be monitored – right-click on any part of the visualization window to select the leads.
- Start monitoring with the Green light icon
- If the baseline moves, use the block function
- Amplification and shift can be set with the mouse or the arrow keys.
During monitoring, one of the two measurement modes can be selected:
I. Storage of „raw” ECG
II. Storage of raw and analyzed ECG
I. Recording, storage and printing out a max. 60 s long part of an ECG
From 5 to 60 sec. of the monitorized ECG can be stored and printed. At the beginning of the monitoring, a yellow line is displayed that marks the filling up of the „Rough ECG storage (max. 60 sec, 100% is equal with 60 sec.). 5 sec. after the start of monitoring two icons are displayed: a floppy and a printer icon. After this, monitoring can be stopped any time if the ECG curves are to be saved. Both icons become activated as soon as the monitoring stopped. Clicking on the icons the latest 1 minute of the ECG is storable. After 60s the ECG curves are overwritten in the storage. The saved ECG is automatically naPet „5s”, as 5 sec. is the shortest storable fraction. (The program writes the whole stored ECG on the disc, the user can determine the length by ending monitoring. E.g.: if the yellow line shows 50%, the stored ECG is 30 sec. of length.).
The stored ECG can be replayed from the rough ECG storage. The time zone indicator next to the printer icon has four icons:
0s: one click: panning, start/stop; double click: panning start from the
beginning of the acceptable fraction (hotkey: r)
<: moving backward (hotkey: Page Down)
>: moving forward (hotkey: Page Up)
roller: (catching left-click on mouse) positioning
Hotkey for printing: p, hotkey for saving :t
Resume monitoring by clicking on the Green light icon or pressing “s”.
II. Storage of raw and analyzed ECG
Measurement and analysis of a 16 sec ECG, storage of averaged cycles
Start the measurement with the Tick icon.
Cardy will carry out a 16 second ECG measurement, analysis, and sends the results over to the PC.
The computer displays the ECG curves that can also be printed with the Printer icon, or saved with the PC icon.
After saving the data, you can edit the medical comment with the “Opinion” tab. The opinion is stored along the ECG measurement and appears on the printout as well. You can display the calculated parameters with the “Parameter” tab.
Filters: Both Cardy and PC program have built-in digital filters, which are operating independently. The Cardy filter can be set in Cardy during monitoring by the “O” button. The 1st push of the button switches on the 50Hz mains filter, next push switches on the 30Hz myogram filter (the mains filter is kept on), and the 3rd push switches both filters off. Usage of filter will not prevent the rejection of noisy ECG - as the analysis is carried out from non-filtered signal - , but it improves the quality of the rhythm curve. The setting of filters is kept by Cardy, even if it is switched off. (The ECG stored in Cardy will be filtered, too, when the filters are set on.) When Cardy filter is switched on, all the raw ECG leads and the rhythm curve will be filtered. Note: When Cardy is used with PC, the rhythm curve - ECG of 16s seen after the averaged cycles - is filtered by the Cardy, not by the PC.
The filters in PC program can be activated during monitoring by clicking the proper icon. When clicking the “30Hz” myogram filter icon, it switches on the 50Hz mains filter, too If they are active, the program will store filtered raw ECG in the database.
To display stored data, find the patient (type the first letter of the patient’s name to jump forward in the list), then open the patient data by clicking on the name. Select the date of the recording by double clicking on it. The ECG curves will be displayed.
To compare ECG curves visually, you can select multiple curves of a particular patient (hold down CTRL while clicking on the curves.) You can view the 6 limb and 6 chest leads separately, but always a maximum of 5 curves at the same time. Click “phone-endoscope” icon after selecting the ECG record to be compared.

CARDY® Pet:Frequently asked questions
Program installation and usage
How many installations can be made with a software: as many, as you wish.
What happens, if reinstalling the Cardy program: will it overwrite the data? No, all the measurements will be preserved.
Error message during installation: “16- bit system does not support application of 32-bit”
Reason: No autoexec.nt file was found in directory: Windows\system32
What to do: Copy autoexec.nt file from Windows\repair directory to Windows\system32 directory
The windows of the program has not proper size (some bottoms /text are missing)
Reason: No 96dpi is set on display
What to do: Set Normal (96DPI) in Display/ Settings/Special/ General menu
The visualized chest leads on PC display are not “ECG like”:
Reason: the Cardy operation mode is set to rhythm or rhythm+ where the Cardy doesn’t transmit chest leads to the PC
What to do: set “P”, “P+” (8 –lead ECG)
The “Cardy/Download new firmware” menu does not offer web-site address.
Reason: this menu is a tool to update the Cardy firmware, not the PC software.
What to do, if you wonder, whether a new firmware exists: ask your dealer.
The Cardy can not be switched on:
Reason1: No battery in or no energy in batteries
Reason2: no proper connection at batteries, check it
Reason3: the equipment has not been used for a long period of time, and the contrast is forgotten because of the lack of battery
What to do: After changing the battery, set the contrast: hold down the O key and down arrow key simultaneously (brightening) or up arrow key simultaneously (darkening)
Checking FS, Error 0x0281 error message on Cardy after switching on, or
Error message “Temp. write protected” before ECG storage
Reason: no flash formatting was made after firmware update
What to do: Format flash in Delete menu, Format Flash:
Be careful: all the data will be lost in
Will the data be kept in Cardy during battery change? Yes
Measurement error during analysis
Reason: During measurement Cardy checks the placement of the electrodes and the technical quality of the ECG. If the electrodes are not connecting well during the measurement, or the ECG is “noisy”, an error message will appear after the ECG sampling:
„High noise CODE: F8” (Most frequent error code is F8, but it can be any error between FF and F0.) Check the placement of the electrodes, check if all the pins are in place, make sure that you are not too near to an electronic device, such as a TV,PC, or especially a power supply of a note-book.(If you use note-book, pull out its power cord from mains during measurement, if the ECG signal is noisy). If everything seems to be in order, press “YES” key, the patient has to relax, and the measurement can be repeated. Note: the filter is used to get noise-free signal on LCD, but the analysis is carried out from unfiltered ECG signal, so you should find the reason of noise and eliminate it.
Noisy ECG, when the ECG record is made by doctor/second person (called: “assistant”)
Reason: the assistant disturbs the measurement by his own electromagnetic field.
What to do: the assistant should be located at a minimal distance of 1 m from the patient during measurement. The assistant should not touch the patient or patient cable during measurement
Communication error during monitoring or downloading
when the processor time of the PC is taken away by some other program, the infra communication can have malfunction.
- do not allow internet communication during Cardy communication (monitoring, or on-line ECG measurement). Windows upgrade is very "selfish": takes the CPU time away for a long time!
- switch off antivirus program (no need for it, if internet is disabled)
- the network communication may disturb Cardy communication

Useful Tips
Switching off: Cardy switches off automatically after 3 minutes of inactivity , but you can manually switch off Cardy by holding pressed the O key for 3 sec’s. (Auto-switch is not active before ECG storage.)
Replacing the battery: A standard alkali battery has an approx. 60 hours (approx. 720 measurement) lifetime. A 1200 mAh rechargeable battery can power Cardy for about 30 hours (360 measurements). An icon shows the battery voltage.
Contrast setting: hold down the O key and ê key simultaneously (brightening) or ékey simultaneously (darkening)
Communication error during monitoring or downloading
when the processor time of the PC is taken away by some other program, the infra communication can have malfunction.
- do not allow internet communication during Cardy communication (monitoring, or on-line ECG
