Refractory and blanking intervals in the context of multi-site left ventricular pacing

摘要

A refractory period for a pacemaker sensing channel refers to a period of time during which the sensing channel is either blind to incoming electrical signals, termed a blanking interval, and/or during which the device is configured to ignore such signals for purposes of sense event detection. Methods and devices for implementing refractory periods in the context of multi-site left ventricular pacing are described.
