With the noninvasive registration of late ventricular potentials there is the possibility to obtain statements about a regionally delayed excitation of ventricular parts which may refer to an increased inclination to ventricular tachyarrhythmias. Late ventricular potentials in patients with suspicion of primary diseases of the myocardium more frequently appeared both in the case of inducible non-sustained or sustained ventricular tachycardias and in the presence of simultaneous fibrous hypertrophy of the myocardium and interstitial fibrosis in the bioptate of the myocardium than in noninducibility of ventricular tachycardias and in the absence of histological changes of the myocardium. Thus in patients with cardiomyopathies a certain predicting significance seems to be ascribed to the evidence of late potentials in the highly increased signal-averaged ECG both for the ability to evoke ventricular tachycardias by programmed ventricular stimulation and for the presence of more distinct histological changes of the myocardium.
通过对晚期心室电位进行无创记录，有可能获得关于心室局部区域延迟激动的信息，这可能与室性快速心律失常的倾向增加有关。在怀疑患有原发性心肌疾病的患者中，与不能诱发室性心动过速以及心肌无组织学改变的情况相比，在可诱发非持续性或持续性室性心动过速的情况下，以及在心肌活检显示心肌同时存在纤维性肥大和间质纤维化时，晚期心室电位更常出现。因此，在心肌病患者中，对于通过程控心室刺激诱发室性心动过速的能力以及心肌更明显的组织学改变，高增益信号平均心电图中晚期电位的证据似乎具有一定的预测意义。
