A 71-year-old male with repaired tetralogy of Fallot and a pacemaker for a sinusnode dysfunction suffered from heart failure symptoms with preserved left ventricular function. Simply changingthe pacemaker’s lower rate from 60 to 75 bpm, New York Heart Association classification improved from III to II,and hemodynamic parameters drastically improved. We regarded this case as informative. Appropriate heart ratecould be higher in congenital patients with failing right and non-failing left ventricles than in adults with malfunctioningLV.展开更多
急性右心功能衰竭(acute right heart failure,ARHF),又称急性右心室综合征(acute right heartsvndrome,ARHS)是由于右心扩张和(或)功能障碍导致体循环充血、组织低灌注、低血压、心肾综合征或心肝综合征等急性进展性综合征[1-3]。右心...急性右心功能衰竭(acute right heart failure,ARHF),又称急性右心室综合征(acute right heartsvndrome,ARHS)是由于右心扩张和(或)功能障碍导致体循环充血、组织低灌注、低血压、心肾综合征或心肝综合征等急性进展性综合征[1-3]。右心衰竭尚没有明确的定量标准,目前倾向性的标准为右心室心脏指数(cardiac index,CI)<2.5L/(min·m2)和右心室充盈压>8mmHg(1mmHg-O.133kPa)。右心衰竭的诊断至少具备2个特征:与右心衰竭一致的症状与体征,或右心心脏结构和(或)功能异常,或右心压力增加的客观依据。展开更多
