Automated on-line measurement of electrophysiologic intervals during cardiac catheterization
Abstract:
A small dedicated, computer-controlled waveform analyzer was used to automatically measure the R-R cycle length, low right atrium to His, and His to ventricle intervals obtained during electrophysiologic studies on 35 patients. These measurements were compared to intervals hand-measured separately and found to correlate well (0.92, 0.83, and 0.75, respectively). The sources of error, possible pitfalls, and future uses of this technique are discussed.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
