Abstract

An 81-year-old male with a history of systolic heart failure due to an underlying ischemic cardiomyopathy with a left ventricular ejection fraction of 13% and QRS duration of 130 ms had undergone an uncomplicated cardiac resynchronization therapy defibrillator implantation (Quadra Assura MP, St. Jude Medical, LV lead (SJM Quartet 1458Q-86), RA lead (Biotronik Safio S53) and RV shocklead (Biotronik Linox Smart S65 ProMRI) in 2015.

摘要

一名81岁男性，有潜在缺血性心肌病导致的收缩性心力衰竭病史，左心室射血分数为13%，QRS波时限为130毫秒，于2015年接受了一次无并发症的心脏再同步化治疗除颤器植入手术（采用圣犹达医疗公司的Quadra Assura MP，左心室导线（圣犹达四分体1458Q - 86），右心房导线（百多力Safio S53）和右心室除颤导线（百多力Linox Smart S65 ProMRI））。
