[Characteristics of ischemic heart disease patients with late ventricular potentials].

The purpose of this study was to compare ischemic heart disease (IHD) patients with and without late potentials (LP) by using noninvasive diagnostic methods as: echocardiographic examination, exercise testing, 24-hours Holter ambulatory monitoring, recording of atrial and ventricular signal-averaged ECG. Examination covered 25 IHD pts (12 male and 13 female) with LP, mean age 58.6 +/- 7.3 (group I) and 100 IHD pts (65 male and 35 female) without LP, mean age 56.8 +/- 8.5 (group II). Summing up, it should be stated that despite showing tendencies to much often occurrences of ventricular arrhythmias on Holter monitoring and silent ischemia during exercise testing in IHD pts with LP we were unable to indicate distinctive differentiating parameters between investigated groups.
