Pacemaker with anti-atrial tachyarrhymia rate soothing

摘要

A soothing program for anti-atrial tachyarrhymia therapy operates within a natural intrinsic atrial rate band for increased patient comport and improved therapy. The implantable pacemakers is configured with an atrial event detector, an anti-atrial tachyarrhymia progam that produces an anti-tachyarrhymia therapy, and a soothing program. The soothing program resides in memory and adjusts the anti-atrial tachyarrhymia program. The soothing program has an acceleration rate within a natural intrinsic atrial rate band upon detection of an atrial tachyarrhymia event and a deceleration rate also within the natural intrinsic atrial rate band to adjust the anti-atrial tachyarrhymia therapy. Some embodiments can adjust the anti-atrial tachyarrhymia therapy to maintain natural atrial activation and reduce patient discomfort such as palpitations.
