title: [The significance of systolic time intervals in the dipyridamole test for the diagnosis of coronary disease].
abstract: The investigations concerning the significance of the systolic time intervals in the dipyridamole test for the diagnosis of the coronary heart disease were carried out in 15 healthy test persons and 40 patients with coronary heart disease. Apart from the systolic time intervals calculated according to Weissler and co-workers also the behaviour of the ST segment, the R wave in lead V5 (RV5) and the sum of the amplitudes of the R waves (sigma R) were estimated concerning sensitivity, specifity and predictive value. At a sensitivity of 65% for the behaviour of the ST segment under influence of the dipyridamole test this was smaller for RV 5, sigma R, ICT and LVET/S1S2, on the other hand greater for PEPI and OS2I (p less than 0.05). The other time intervals did not differ in their sensitivity to the ST segment. The specifity and the predictive confirming value were 100% for the changes of the ST segment. In the analysis of the other parameters no differences were stated (p greater than 0.05). The predictive value, excluding a coronary heart disease, was 51.7% for the ST segment and still higher for PEPI and OS2I (p less than 0.05). By the analysis of the systolic time intervals the diagnosis value of the dipyridamole test continues to increase.
