A Voltage-Triggered System for Adaptive Sampling in Body Surface Mapping

Cardiac electrophysiological waveforms are particularly well suited for adaptive sampling since they are periodic and contain some segments of both rapid and slow change. Rather than sampling at a constant rate, adaptive sampling allows the sampling rate to change according to the rate at which new information is received. This study considered the effectiveness of a voltage-triggered system as a means for adaptive sampling during QRST of the cardiac cycle.
