In 34 patients with chest pain the spatial orientation of the ST-vectors in the exercise electrocardiogramm 30 and 80 msec after the end of QRS were compared with the location of exercise induced local defects of myocardial uptake of 201T1. The following results were obtained:

1. The sensitivity and specifity of myocardial perfusion imaging after exercise were the same as those of exercise electrocardiograms;

2. No relation could be observed between the location of reduced 201T1 uptake during exercise and the spatial orientation of the ST-vectors.

Untersucht wurde bei 34 Patienten mit Angina pectoris die räumliche Orientierung des ST-Vektors 30 und 80 msec nach Ende von QRS und mit der Lokalisation eines in der 201T1-Szintigraphie unter Belastung aufgetretenen Defektes verglichen. Folgende Ergebnisse wurden erzielt:

1. Die Sensitivität und Spezifität der Myokard-Szintigraphie unter Belastung waren identisch mit denen des Belastungs-EKG;

2. Die unter Belastung aufgetretenen 201T1-Defekte zeigten keine räumliche Beziehung zu der Raumlage des ST-Vektors.
