Brazilian Journal of Cardiovascular Surgery, 2022 Coordinated and harmonic (synchronous) ventricular electrical activation is essential for better left ventricular systolic function. Intraventricular conduction abnormalities, such as left bundle branch block due to artificial cardiac pacing, lead to ...

Journal of Arrhythmia, 2016 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).

Physiological cardiac pacing: Current status
Indian Heart Journal, 2016 Adverse hemodynamics of right ventricular (RV) pacing is a well-known fact. It was believed to be the result of atrio-ventricular (AV) dyssynchrony and sequential pacing of the atrium and ventricle may solve these problems.

Right ventricular pacing-induced hypotension [PDF]
Heart, 2006 A cardiologist was consulted to evaluate a patient with intermittent hypotension. A 71-year-old woman with a history of coronary artery disease and coronary bypass surgery, type 2 diabetes and sick sinus syndrome s/p dual-chamber pacemaker …

Sudden failure of ventricular pacing and recovery in a patient with cardiac sarcoidosis
Journal of Arrhythmia, 2017 A 76-year-old woman with sarcoidosis who had an implantable pacemaker for complete atrioventricular block was admitted with syncope. Electrocardiogram revealed ventricular pacing failure, and a marked rise in the ventricular pacing threshold.

Cardiac Memory-induced T-wave Inversions [PDF]
, 2020 Introduction: Cardiac memory refers to T-wave inversions that result when normal ventricular activation resumes following a period of abnormal ventricular activation.Case Report: We present a case of a 29-year-old man with a pacemaker who presented with ...

Role of cardiac resynchronization therapy in the development of new-onset atrial fibrillation: A single-center prospective study. [PDF]
, 2012 Albeit several studies examined the association between cardiac resynchronization therapy (CRT) and atrial fibrillation (AF) in heart failure (HF), results are still unclear and quite conflicting.

Indian Pacing and Electrophysiology Journal, 2014 Right ventricular apical pacing may cause or worsen mitral regurgitation (MR). Potential mechanisms for this adverse sequelae include intraventricular dyssynchrony, altered papillary muscle function, pacing-induced cardiomyopathy with left ventricular ...

Ventricular pacing: to pace or not to pace [PDF]
Europace, 2009 Pacing from the right ventricular apex has been the clinical standard for decades but has recently come into question with a growing trend towards reducing ventricular pacing as much as possible. The earliest devices provided asynchronous ventricular pacing in patients whose indication for pacing was asystolic complete heart block. RV apical pacing was

Journal of Arrhythmia, 2006 The patient was a 67-year-old female diagnosed with dilated cardiomyopathy. She had chronic atrial fibrillation (AF) with bradycardia and low left ventricular function (left ventricular ejection fraction (LVEF) 40%). She was admitted for congestive heart
