Abstract

A 52-year-old man, living at home, had been on left ventricular assistance for 15 months with a Novacor pump (Worldheart, Ottawa, ON, Canada). Following the onset of effort dyspnea that had recently become worse, he was admitted to the hospital. A review of the pump showed that its flow rate had significantly decreased. An electrocardiogram showed a third-degree atrioventricular block. A pacemaker was implanted and the patient became asymptomatic immediately afterwards. This clinical case report shows the importance of satisfactory right ventricle filling in these patients. Right ventricle filling can be impaired by conduction disorders.

摘要

一名52岁的男性居家生活，使用诺瓦科尔泵（世界心脏公司，渥太华，安大略省，加拿大）进行左心室辅助已达15个月。在近期加重的劳力性呼吸困难发作后，他被收治入院。对该泵的检查显示其流速显著降低。心电图显示三度房室传导阻滞。植入了起搏器，患者随后立即症状消失。本临床病例报告显示了这些患者中右心室满意充盈的重要性。传导障碍可能会损害右心室充盈。
