    Abstract:
    To assess the value of late potential recordings in predicting complex ventricular arrhythmias in chronic coronary heart disease, signal-averaged ECG and 24-h Holter were performed in 101 consecutive patients following coronary arteriography. In 69 of 101 patients, non-sustained ventricular tachycardia (VT) (22 patients) or monotopic or polytopic ventricular premature beats (VPB) (47 patients) were detected. When the different patient groups (VT, VPB, no arrhythmias) were compared, the parameters defining the late potentials demonstrated broad variability. Patients with non-sustained ventricular tachycardia showed a tendency to increased late potentials, though this tendency was not significant. In patients with pathologic late potentials the predictability of non-sustained ventricular tachycardia was only 38%. - It is therefore concluded that late potentials in patients with chronic coronary heart disease are not directly linked to the extent and severity of arrhythmias recorded in the ambulatory 24-h Holter.
