title: [Changes in ECG indicators during bicycle ergometry in patients having suffered myocardial infarction].
abstract: Altogether 218 patients with a history of myocardial infarction were subjected to bicycle ergometry. The ECG recorded at the height of the exercise showed a significant increase in the heart rate and in the amplitudes of P and R waves. The diastole and electric systole shortened. As the load was raised, the rate of A-B conduction was relatively decelerated.
