CORRELATION OF SIGNAL AVERAGING WITH PROGRAMMED STIMULATION IN HCM PATIENTS

信号平均心电图(SAE)检测迟发性心脏病 电位(LP)是一种检测患者的非侵入性方法 有自发性脑室。这项研究的目的是 确定SAE与持续的诱导性之间的相关性 程序刺激(PS)侵袭性室性心动过速 在30例肥厚型心肌病患者中。结果表明， 基于某些LP指数，SAE具有敏感性和 对诱导性室速的特异性分别为85%和94%。 我们得出结论，SAE是一种有用的非侵入性检查，在 除PS外，可能有助于识别HCM患者的电子 心脏不稳定的人，可能有心脏猝死的危险。

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.
