title: [Apexcardiography in coronary disease].
abstract: The value of the apex cardiogram (AKG) for identification of diastolic extrasounds is established. The present study attempts to correlate the so called a-wave index and the systolic portion of the AKG-curve with the results of left heart catheterisation in 15 patients with coronary heart disease (KHK). The position of point U (the lowest point between the first and the second systolic wave) during mechanical systole and the relative height of the second systolic wave do not correlate with LVEDP, dp/dt and the a-wave index. In contrast to a group of 22 healthy persons the a-wave index of the KHK-patients was significantly higher (17.5% vs. 5.7% on average) and the position of point U was significantly earlier (42.5% vs. 62% on average, of the duration of mechanical systole).
