ABSTRACT
We have explored the systolic time intervals of 52 patients with angina pectoris at the time of their hospitalization in our wards. Our results are in close agreement with published data, essentially indicating prolongation of the preejection time and shortening of the ejection time. These alterations of systolic times can be interpreted pathophysiologically as as expressing reduced myocardial contractility. The long PEP-short LVET polygraph picture, occurring in the course of chronic ischemic heart disease, reveals the deficit of myocardial contractility at a stage of the disease at which clinical evidence of left ventricular failure is usually not yet detectable.

Three cases of angiodysplasias are reported. There are some problems still open concerning diagnostic and therapeutic approach. In this paper we try to correlate localisation, time of onset, size, aspect, histological features, evolution, side effects and hemodynamic problems with diagnosis, prognosis and therapy of childhood angiodysplasias mainly concerning cavernous, intracranial, visceral and lymphatic angiomas.
