One way in which cardiac resynchronization therapy may be delivered is to only deliver paces to the left ventricle. If left ventricular pacing is inhibited during a cardiac cycle, it may be desirable to deliver a right ventricular safety pace to prevent asystole. Methods and devices for implementing right ventricular safety pacing in the context of multi-site left ventricular-only pacing are described.

摘要:
In a pacing mode where the left ventricle is paced upon expiration of an escape interval that is reset by a right ventricular sense, there is the risk that the left ventricular pace may be delivered in the so-called vulnerable period that occurs after a depolarization and trigger an arrhythmia. To reduce this risk, a left ventricular protective period (LVPP) may be provided. Methods and devices for implementing an LVPP in the context of multi-site left ventricular pacing are described.

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.

A method and system for managing refractory periods in a cardiac rhythm management device configured for biventricular or biatrial sensing. Refractory periods for each channel of the pacemaker are provided by interval timers that are triggered by sensed or paced events in order to prevent misinterpretation of sensing signals.
