ECG recorder,portable,w/access

Electrocardiographs are used to diagnose cardiac abnormalities, determine a patient's response to drug therapy, and reveal trends or changes in heart function. Multichannel electrocardiographs record and display signals from two or more leads simultaneously. Electrocardiographs differ from ECG monitors, which provide a continuous real-time display of the ECG waveform and other physiologic measurements on a screen and warn of potentially life-threatening or precursor rhythms. 
Electrocardiographs detect the electrical signals associated with cardiac activity and produce an ECG, a graphic record of the voltage versus time. They are used to diagnose and assist in treating some types of heart disease and arrhythmias.
