[Electrocardiographic inferences as a cause of diagnostic errors].

The authors analyzed the cause of diagnostic errors due to incorrect ECG interpretation. It was revealed that the cause for diagnostic errors may lie in the inadequate experience of the electrocardiologist , the overestimation of the method potentialities and the absence of the commonly accepted language of ECG interpretation. The necessity is emphasized of the clear cut differentiation between the electrophysiological and clinical-morphological approaches to the formation of the language of ECG interpretation. The clinical-morphological approach in clinical practice is acceptable only provided that the electrocardiologist is acquainted with the clinical picture of the disease. The use of this approach disregarding the clinical findings constitutes one of the causes of diagnostic errors and iatrogenia .

[Study of cardiac rhythm disorders in healthy men].

The authors examined 1293 sportsmen engaged in different types of sporting activity and of a different level of mastership in their line and 482 young men who never went in for sports. They were subjected to electrocardiographic investigations with continuous recording of 100 cardiac cycles. The ECG analysis showed that sportsmen have disorders of cardiac rhythm in a statistically significant higher proportion of cases. The depressed activity of the sinus pacemaker is especially frequent which shows "arrhythmias of depressed sinus node" and extrasystoles. The latter in sportsmen are due to pathological changes related to the foci of chronic infections, myocardial dystrophy due to chronic physical overexertion and marked myocardial hypertrophy.

[Mitral valve prolapse syndrome in athletes].

The syndrome of mitral valve prolapse was diagnosed by means of echocardiography in 11 of 28 top-class athletes with functional systolic murmurs and in 4 of 16 athletes examined irrespective of the physical findings and complaints. The echocardiographic manifestations of the prolapse consisted in delayed systolic flexion of the posterior cusp (3 cases), early systolic prolapse of the posterior cusp (4) and holosystolic prolapse of both cusps (8). It is concluded that the syndrome of mitral valve prolapse occurs in athletes far more often than generally supposed and may be the cause of systolic murmurs, and the development of myocardial dystrophy due to chronic physical overstrain and disorders of cardiac rhythm.
