Abstract
An R-wave detection system includes an electrode for placement in close proximity to or in contact with a heart to sense electrical activity of the heart. A signal processor 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.
