Paced QRS morphology mimicking complete left bundle branch block induced by right ventricular pacing is associated with pacing?induced cardiomyopathy

Journal of Cardiovascular Electrophysiology

Complete left bundle branch block (CLBBB)-like QRS morphology of right ventricular pacing at pacemaker implantation satisfying the American Heart Association/American College of Cardiology Foundation/Heart Rhythm Society criteria of CLBBB was associated with development of pacing induced cardiomyopathy.

Chest pain, shortness of breath, T wave inversion, and rising troponin in a young healthy runner.

Dr. Smith's ECG Blog

A nice Review of EIA by Molis and Molis can be found in Sports Health 2:311-317, 2010. This gradual change in P wave morphology as the heart rate varies could be consistent with a wandering atrial pacemaker.

Incidence and Outcomes of New-Onset Right Bundle Branch Block Following Transcatheter Aortic Valve Replacement

Circulation: Arrhythmia and Electrophysiology

Hence, we sought to characterize the incidence of post-TAVR RBBB and determine associated risks of permanent pacemaker (PPM) implantation and mortality.METHODS:All patients 18 years and above without preexisting RBBB or PPM who underwent TAVR at US Mayo Clinic sites and Mayo Clinic Health Systems from June 2010 to May 2021 were evaluated.

Cardiac resynchronization therapy (CRT) – why is it so important?

Cardiomatics

This can be achieved by introducing electrodes into the vascular system which are connected to a pacemaker with a resynchronization function. Circulation 2010, 122, 2022–2030. [6] The aim of CRT is to restore physiologically normal electrical heart activity, which is often altered in the course of the underlying disease. Heart Fail.

Negative predictors of adverse outcome: Pacemaker Pre-syncope or "near-syncope," but there is still some small risk (5, 18) These last two are identified in studies, but I consider them dangerous signs and symptoms in their own right, as above: 10. —QRS J Am Coll Cardiol, 2010; 55:713-721, doi:10.1016/j.jacc.2009.09.049
