Successful resynchronization by permanent His-bundle pacing in a patient with pacing-induced cardiomyopathy
Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM). While upgrading to biventricular pacing (BiVP) is an effective therapy for PICM, permanent His-bundle pacing (HBP) can be a physiological alt...
متن کاملRapid reversal of right ventricular pacing–induced cardiomyopathy by His bundle pacing
Case report A 78-year-old woman with hypertension, paroxysmal atrial fibrillation treated with pulmonary vein isolation 4 years prior, and normal biventricular systolic function presented with symptomatic high-grade heart block with junctional escape rhythm and QRS duration of 84 ms (Figure 1A). She underwent dual-chamber pacemaker implantation with apical RV lead placement and resolution of he...
متن کاملHis Bundle Pacing: Techniques and Outcomes.
Traditional right ventricular pacing prolongs the electrical and mechanical activation of the heart, which reduces the pump function, and in selected patients may lead to pacing-induced heart failure. Pacing the His bundle preserves the normal or near-normal activation pattern of the ventricles that prevents the detrimental effects of right ventricular pacing. This review discusses the techniqu...
متن کاملAcute His Bundle Injury during Permanent His Bundle Pacing: Mechanistic Insights into Intra- Hisian Block
Permanent His bundle pacing (HBP) is a physiological alternative to right ventricular pacing. Acute injury to the His bundle can occur during permanent HBP in the form of transient or permanent bundle branch blocks. Observations of mechanical injury to the His bundle during HBP lead fixation and electrophysiological response to HBP provides additional mechanistic insights into the pathology of ...
متن کاملHis Bundle Pacing Or Biventricular Pacing For Cardiac Resynchronization Therapy In Heart Failure: Discovering New Methods For An Old Problem.
Heart failure (HF) is one of the biggest epidemics of modern cardiovascular medicine. Cardiac resynchronization therapy (CRT) with biventricular (BiV) pacing has proven to have an integral role in the management of patients with reduced left ventricular (LV) function and left bundle branch blocks (LBBB). However, CRT with BiV pacing is not always feasible and even when it is, the percentage of ...
