[Value of recording late ventricular potentials in patients with a history of myocardial infarction].
The aim of the work was to determine the values of the registration of late ventricular potentials (PPK) in order to identify patients with paroxysmal ventricular tachycardia following myocardial infarction. PPK was found in 26 out of 30 patients (87%) with episodes of ventricular tachycardia and only in 6 out of 50 (12%) patients without such rhythm disorders following myocardial infarction (p less than 0.001). No PPK were found in any of 25 healthy persons of the control group. No significant difference was found in the frequency of complex ventricular extrasystolic beats (III-V cl. according to Lown) in 24-hour ambulatory electrocardiogram between patients with paroxysmal ventricular tachycardia (47%) and patients without such episodes in anamnesis (30%). The recording of PPK in chest surface leads makes it possible to identify patients with paroxysmal ventricular tachycardia following cardiac infarct.
