Each portion of an ECG reading is divided into five waves or collectively three sections. An ECG (electrocardiogram) simulator is an electronic tool that plays an essential role in the testing, design, and development of ECG monitors and other ECG equipment. Defibrillation is another noise source that requires input circuit. These patients are prone to develop atrial tachyarrhythmias in which a reentry circuit is set up between the normal AV nodal pathway and the accessory tract (Figure 2). University of Central Florida. The length of the re-entry circuit corresponds to the size of the right atrium, resulting in a fairly predictable atrial rate of around 300 bpm (range 200-400). To prevent overlapping of the ECG deflections, some ECG machines automatically adjust the calibration of the ECG. The ECG can be used to detect heart disease, heart attack, abnormal heart rhythms and an enlarged heart condition that may cause heart failure. 6, NOVEMBER 2009 897 A Wearable ECG Acquisition System With Compact Planar-Fashionable Circuit Board-Based Shirt.
