Background Frequent right ventricular (RV) pacing can lead to a decline in left ventricular
ejection fraction (LVEF). Objective This study aimed to identify incidence and predictors of …

In patients receiving permanent cardiac electrical stimulation, a high burden of apical right
ventricular pacing is associated with an increased incidence of heart failure. Despite the …

Background A meta‐analysis of randomized controlled trials (RCTs) was conducted to
compare the effects of right ventricular nonapical (RVNA) and right ventricular apical (RVA) …

Abstract Background Pacemaker induced Cardiomyopathy (PICM) is an easily overlooked
cause of heart failure with reduced ejection fraction. Data regarding this complication are …

Objective Knowledge of factors causing pacing-induced cardiomyopathy (PICM) is
incomplete. We sought to estimate the incidence and predisposing factors for PICM and …

Background Long-term RV pacing leads to ventricular dyssynchrony, in the form of LBBB-
like morphology, with subsequent detrimental effects on LV structure and function. Three …

目的: 运用超声心动图(ultrasonic cardiogram, UCG) 评价右室心尖部(right ventricular apical,
RVA) 起搏及右室间隔部(right ventricular septal, RVS) 起搏对完全性房室传导阻滞患者左室 …

FUNDAMENTO: A estimulação de ventrículo direito pode ser deletéria em pacientes com
disfunção ventricular, porém, em pacientes com função normal, o impacto desta …

Background: Pacing-induced cardiomyopathy (PICM) is a clinical syndrome that is
characterized by a drop in the left ventricular ejection fraction (LVEF) due to chronic high …

Objectives Our study aimed to demonstrate the early negative impact of right ventricular
apical pacing induced by single (VVI) and dual chamber (DDD) pacemakers on LV functions …
