美国Annpam医师在2016年5月HRS学术年会发表的文章指出,当植入的皮下ICD或ICD等心律植入装置恰好位于心室肌与胸前导联之间时,可增加两者间的阻力,进而能降低心电图胸前导联QRS波的幅度,使这些导联的QRS波的幅度比植入前低。其报告了一例心尖肥厚型心肌病患者,晕厥后经超声心动图检查确定了该诊断,MRI显像证实在患者室间膈下部存在延迟显像增强。随后给患者植入了S-ICD进行一级预防。S-ICD植入前心电图存在左 An article published by Dr. Annpam at the HRS Academic Conference in May 2016 pointed out that the resistance between the ventricular and precordial leads may be increased when an implanted subcutaneous ICD or ICD rhythm device is placed between the ventricular and precordial leads , Which in turn reduces the magnitude of QRS waves in the lead of the chest ECG and makes the amplitude of QRS waves in these leads lower than before implantation. It reported one patient with apical hypertrophic cardiomyopathy confirmed by echocardiography after a syncope and confirmed by MRI imaging that delayed imaging was present in the subdiaphragmatic region of the patient. The patient was then implanted with S-ICD for primary prevention. S-ICD pre-implantation ECG left
