title: [The behavior of the a and the t indices and the systolic times in myocardial infarct].
abstract: A study of the behaviour of the a and telediastolic indices and systolic times in patients presenting the sequelae of myocardial infarction is reported. It is pointed out that the earliness of a and t index variations with respect to those of systolic times is an indication of the sensitivity of the investigation which offers invaluable pointers to subsequent treatment. It is also stressed that previous hypertension and/or coronaropathy are more important than the infarction itself in creating dyskinetic zones of the myocardium and, consequently, the haemodynamic changes observed with phonomechanocardiography.
