[ECG and hemodynamics in experimental coronary thrombosis induced by direct current in the closed thorax of the dog and mini-pig].

Coronary thrombosis is a life-threatening disease that, as a rule, leads to myocardial infarction. The onset and the course of this disease are followed in animal experiments with the aid of electrocardiograms and some haemodynamic parameters. There was a biphasic course, i.e., the authors observed first a rise and then a striking drop in peripheral arterial pressure and a rise in central venous pressure. The electrocardiograms and blood-pressure controls evidenced that the induction of coronary thrombosis is more difficult in the minipig than in the dog.
