Unconventional applications in pacemaker therapy

Since its inception, the principal application of permanent pacing has been for the correction of symptomatic bradycardia. During the past 3 decades, pacemaker therapy indications have evolved, through scientific research and through advances in technology, beyond conduction system disorders and sinus node dysfunction. This article presents recent progress in the application of permanent pacing in hypertrophic obstructive cardiomyopathy, dilated cardiomyopathy, paroxysmal atrial fibrillation, neurocardiogenic syncope, and in long-QT syndrome. In each clinical entity, certain pacing parameters are crucial for achieving the therapeutic goal. Advanced practice clinicians will encounter these patients in practice and are urged to recognize the therapeutic goal and optimal function of the device.
