Tips for buying Single Channel ECG

1. The Single Channel ECG (single channel EKG) device should measure all basic axes and durations including, RR, PQ, QT, ATC, P, QRS, T, and HR. It should have indicators for battery status, loose electrode contact, system status, and artifacts.
2. The Single-Channel Electrocardiograph should be able to store ECG waveforms for later retrieval, printing, and transmission to enable entering patient data by the operator. Each record should include the patient's name or ID number, age, sex, weight, and height as well as the recording date and time, sensitivity setting, chart speed, and leads being recorded.
3. The Single Channel ECG device should have an RS232 port or another appropriate digital interface to allow communications with other electrocardiographs, computers, or data management systems. It should store at least 20 ECGs and have expandable storage capability.
4. The Single Channel ECG device should provide sensitivity settings of at least 2.5, 5, 10, and 20 mm/mV; the recorders will have a chart speed of 5, 10, 25, and 50 mm/sec.
5. The batteries in a battery-operated Single Channel EKG unit should be rechargeable; such a unit should operate on battery for at least 8 hours and should be able to be charged while connected to line power.
6. Battery powered Single Channel ECG units should have a clear low battery indicator to make sure the batteries are being recharged, on the outside of the unit. The fact that the charger is plugged into an AC outlet is not enough.
7. Single channel electrocardiographs are cheaper than other electrocardiography recorders. They are also light, simple, and compact, and therefore convenient for use in special situations of rapid testing - often outside the usual clinical setting.
8. Spare parts for single channel ECG unit devices are often available and inexpensive; the maintenance of these instruments is fairly simple.
9. Some electrocardiographs can store rhythm strips for later retrieval; some systems allow transmission of ECG data, and many others can communicate with a data management system, allowing the report to be stored.
10. Optional carts may be used to turn the larger Single Channel ECG devices into more transportable units, to provide a working surface for the user, and to store spare lead wires, electrodes, and recording paper.
