WebApr 3, 2013 · Atrial Tracking Recovery (ATR) is designed to help the device recover atrial tracking when it is lost because of PVCs or a fast conducted atrial rhythm that inhibits pacing in the ventricles. This restoration of atrial tracking helps maintain AV synchrony and ensures continuous biventricular (BiV) pacing in cardiac resynchronization therapy (CRT). WebNov 17, 2024 · A pacemaker is a small battery-operated device that helps the heart beat in a regular rhythm. Traditional pacemakers have three parts: a generator, wires (leads) and …

WebAdaptivCRT™ is a dynamic, physiologic pacing algorithm that enhances cardiac resynchronization therapy (CRT) by adjusting CRT parameters automatically with changes in patient activity levels and conduction status. It leverages a patient’s intrinsic RV conduction when possible while still maintaining CRT. AdaptivCRT also provides continuous ...
