Ventricular tachycardia(VT) is well known as the life-threatening arrhythmia. It would be important for predicting the risk of VT to prevent sudden death caused by VT after myocardial damage such as old myocardial infarction and dilated cardiomyopathy. In this study, we examined late potential(LP), TWA alternans(TWA), and QTc dispersion(QTcd) measured by Holter ECG, in 21 patients with old myocardial infarction(OMI) and 21 patients with dilated cardiomyopathy(DCM), and evaluated these parameters in relation with the occurrence of VT on these patients. The sensitivities of LP, TWA, and QTcd in patients with OMI in relation with VT were 82%, 73%, and 82%, respectively, and those in patients with DCM were 82%, 93%, and 73%, respectively. The specificities of LP, TWA, and QTcd in patients with OMI in relation with VT were 100%, 40%, and 100%, respectively, and those in patients with DCM were 100%, 30%, and 100%, respectively. The data demonstrated that LP and TWA were the useful predictive parameters for the VT on myocardial damage such as OMI and DCM.
