[Sick sinus node syndrome and the transitory collapse of the R wave in myocardial infarct].
The authors observed 40 patients (7.79%) with the morbid sinus node syndrome among the treated 526 patients with acute myocardial infarction at the department of intensive care during the period 1973--1976. Thirty one were males and nine--females. The syndrome was manifested, in all patients followed up, during the first 14 days after the onsed of the coronary incidence. One case was with a lethal end. Ten patients (1.90%) were observed with the syndrome "transitory collapse of R-deflection" in the separate precordial leads. Half of them had a combination of both syndromes. The collapse of R-deflection was manifested between the 3rd and 14th day in all cases. The character and incidence of rhythm-conductivity disturbances accompanying both syndromes are discussed.
