Abstract

We describe a patient with hemodynamic deterioration and worsening mitral regurgitation related to right ventricular apex pacing. Time-dependent changes in papillary muscle contraction as well as ventricular remodeling by right ventricular apex pacing might be responsible for this rare but serious complication.

摘要

我们描述了一名与右心室心尖部起搏相关的血流动力学恶化和二尖瓣反流加重的患者。乳头肌收缩的时间依赖性变化以及右心室心尖部起搏引起的心室重构可能是这种罕见但严重并发症的原因。
