Abstract: Pacemaker-initiated atrial fibrillation during competitive atrial pacing is a common arrhythmia with potentially serious consequences The novel pacing method proposes a novel way to automatically detect and diagnose competitive atrial pacing, and to deliver an intervention via a pacing stimulus in the atrium simultaneously with delivering a pacing stimulus in the ventricle, and doing this after a longer waiting period. By doing this, potentially hazardous scenarios causing atrial fibrillation in competitive atrial pacing are avoided, while the rhythm regularity and the synchrony between the upper and lower chambers of the heart are maintained. At the same time, the vicious cycle of retrograde conduction from the ventricle to the atrium—the culprit of the problem—is terminated and not allowed to reoccur for several subsequent cardiac cycles, thereby preventing the extended propagation of repetitive non-reentrant ventriculo-atrial synchrony.

Abstract: A method for identifying reversible cardiac dyssynchrony (RCD) of a patient and treating the RCD measures an event relating to a rapid increase in the rate of pressure increase within the left ventricle. The method calculates a first time delay between the event and a first reference time. If the first time delay is longer than a set fraction of electrical activation of the heart, then the presence of cardiac dyssynchrony in the patient is identified. Pacing is applied to the heart, and a second time delay between the event following pacing and a second reference time following pacing is calculated. If the second time delay is shorter than the first time delay, the method identifies a shortening of a delay to onset of myocardial synergy, OoS, thereby identifying the presence of RCD in the patient. Treatment of the RCD is performed.
