  • Title: [Value of the measurement of the repolarization rate in the diagnosis of ischemic heart disease during the veloergometric test].
    Author: Khalfen ESh, Klochkov VA.

    Abstract:
    To assess the bicycle ergometry test, use was made of the indicator of the repolarization rate suggested by the authors. This indicator was calculated according to the first derivative end part of the ventricular complex as a quotient obtained by division of the amplitude of its second phase by the magnitude of the first phase amplitude. In normal subjects at rest, the rate indicator was equal to 1.6 on the average, whereas in patients with angina pectoris, to 1.2-1.5. During the bicycle ergometry test, the indicator decreased to 1.0 (under an average load of 125 W in normal subjects and 25-75 W in angina pectoris patients). The change of the rate indicator to 1.0 outstripped by 40.6 W the moment of recording the conventional criteria of bicycle ergometry test discontinuation. The assessment of the repolarization rate during the bicycle ergometry tests enables one to apply small loads, thereby making the test practically safe and expanding the possibilities of its use.
