CORRELATION OF SIGNAL AVERAGING WITH PROGRAMMED STIMULATION IN HCM PATIENTS

信号平均心电图（SAE）检测晚期 电位（LP）是一种用于检测患者的非侵入性方法 伴有自发性心室。 本研究的目的是 确定SAE与持续性 程控刺激侵入性室性心动过速 30例肥厚型心肌病患者。 结果表明 基于某些LP指标，SAE具有敏感性， 特异性分别为85%和94%。 我们的结论是，SAE是一种有用的非侵入性测试， 除了PS可能有助于识别HCM患者与电 心室不稳定，可能有心脏性猝死的风险。

Signal averaged electrocardiographic (SAE) detection of late potentials (LP) is a non-invasive method for detection of patients with aubythmogenic ventricle. The purpose of this study was to determine the correlation between SAE and inducibility of sustained ventricular tachycardia invasively by programmed stimulation (PS) in 30 patients with hypertrophic cardiomyopathy. The results show that based on certain LP indices SAE had a sensitivity and specificity of 85% and 94% respectively for induced VT. We conclude that SAE is a useful non-invasive test which in addition to PS may help to identify HCM patients with electrically unstable ventricles who may be at risk of sudden cardiac death.
