[Use of functional electrocardiographic tests for detecting and evaluating disorders of cardiac rhythm in young people].
Ten-minute-long resting electrocardiograms and functional tests (respiratory arrest, hyperventilation, orthostatic and exercise tests) under continuous cardiac rhythm monitoring were conducted in 239 young subjects between 10 and 35 years of age (153 skilled athletes, 62 apparently normal individuals and 24 young unskilled athletes). Arrthythmias were detected in 124 (51.9%) of those. Complex arrthythmias were particularly common in skilled athletes, as compared to normal subjects and young unskilled athletes (58.2, 45.2 and 29.2%, respectively). Cardiovascular abnormalities were found in 30.7% of skilled athletes and 9.7% of normal subjects. Electrocardiographic functional tests allow timely identification of athletes with cardiovascular abnormalities and the choice of correct therapeutic strategy in terms of stress exposure.
[Atrial complex in bronchial ECG leads].
The authors suggest a probe electrode by means of which the ECG may be recorded in the bronchial leads simultaneously from four levels of the atrioventricular zone. The P wave of bronchial ECG's was analysed in 24 patients who had no pathological changes in the respiratory organs and cardiovascular system in comparison with similar indices of routine ECG's. The informativeness of ECG's recorded in the bronchial leads in study of the bioelectric activity of the right and left atria is determined. It is pointed out that esophageal leads may be used for analysing the electric activity of the right atrium when they are recorded from the level of an electrode (28.5--31.5 cm) introduced into the esophagus.
