DIGITAL ECG DETECTION SYSTEM

摘要

An R-wave detection system includes an electrode (12) for placement in close proximity to or in contact with a heart to sense electrical activity of the heart. A signal processor (16) is in communication with the electrode, and is responsive to receipt of the analog signal from the electrode to condition the signal to account for noise, and far field effects. The system is operative to determine whether the conditioned signal exceeds a dynamic threshold value, and, if so, the system generates a synchronization pulse to indicate the rising edge of an R wave.
