[Correlation of the results of high-amplification ECG and the cycle of induced ventricular tachycardia. Prognostic value].
Analysis of high amplification ECG results as a function of the results of programmed ventricular stimulation on the fate of 240 patients provides the following data: when programmed ventricular stimulation is negative, there are no late potentials since sudden cardiac death is probably due not to a disturbance in primary rhythm but to a disturbance in ischaemic rhythm; in the case of sustained ventricular tachycardia, cardiac mortality is highest (16 per cent) when due to sudden cardiac death or ventricular tachycardia and late potentials are usually present (14 times out of 15); ventricular fibrillation or flutter are accompanied by appreciable cardiac mortality (between 10 and 13 per cent), basically due to sudden cardiac death and, in this case, there are no late potentials. It is possible to observe late potentials which induce ventricular flutter in subjects during programmed stimulation and this might be a risk factor in the subsequent development of ventricular tachycardia.
