许多研究已经证实,室速(VT)、室颤(VF)等恶性心律失常(MA)是心脏病患者猝死的主要原因之一.Q-Tc间期延长是心脏病患者恶性心律失常的主要原因之一,但Q-Tc间期尚受室内传导障碍(IVCD)的影响,IVCD者Q-Tc间期亦可延长,但这种Q-Tc延长与心律失常的关系未见报道.作者分析测定210例IVCD者Q-Tc间期,初步探讨这种Q-Tc延长与心律失常的关系,从而说明J-Tc间期能更好地反映心室肌复极状况.

Many studies have confirmed that ventricular tachycardia (VT), ventricular fibrillation (VF) and other malignant arrhythmias (MA) is one of the major causes of sudden death in patients with heart disease.Q-Tc interval prolongation is the main cause of malignant arrhythmia in patients with heart disease However, the Q-Tc interval is still influenced by IVCD, and the Q-Tc interval in IVCD is also prolonged. However, this relationship between Q-Tc prolongation and arrhythmia has not been reported. 210 cases of IVCD Q-Tc interval, preliminary study of this relationship between Q-Tc prolongation and arrhythmia, indicating that J-Tc interval can better reflect ventricular repolarization.
