[Mitral valve prolapse syndrome in athletes]. 1979

A G Dembo, and E V Zemtsovskiĭ

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.

D008297 Male Males
D008945 Mitral Valve Prolapse Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.

D010701 Phonocardiography Graphic registration of the heart sounds picked up as vibrations and transformed by a piezoelectric crystal microphone into a varying electrical output according to the stresses imposed by the sound waves. The electrical output is amplified by a stethograph amplifier and recorded by a device incorporated into the electrocardiograph or by a multichannel recording machine. Phonocardiographies
D004452 Echocardiography Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.

D004562 Electrocardiography Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY. 12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead

D006337 Heart Murmurs Heart sounds caused by vibrations resulting from the flow of blood through the heart. Heart murmurs can be examined by HEART AUSCULTATION, and analyzed by their intensity (6 grades), duration, timing (systolic, diastolic, or continuous), location, transmission, and quality (musical, vibratory, blowing, etc).
