Vi. Denisyuk et al., CLINICAL AND ELECTROCARDIOGRAPHIC PRODROM ES OF FATAL CARDIAC-ARRHYTHMIAS IN PATIENTS WITH ACUTE MYOCARDIAL-INFARCTION, Kardiologia, 33(10), 1993, pp. 43-45
The authors made a retrospective analysis of case histories of 201 pat
ients who had died of fatal cardiac arrhythmias, The predictors of the
ir death were ventricular fibrillation in 133 (66.2%) patients, asysto
le in 68 (32,8%), electromechanical dissociation in 2 (1%). Terminal s
inus tachycardia, atrial fibrillation and flutter, the second-third de
gree atrioventricular block, the third-fifth grade ventricular extrasy
stole were the most common clinical and electrocardiographic prodromes
of ventricular fibrillation. In the development of the latter, variou
s mixed disturbances of cardiac rhythm and conduction in combination w
ith prolonged Q-T interval were of more unfavarouble value. Asystole w
as more frequently preceded by the second-third degree atrioventricula
r block, complete bundle branch block, third-fifth grade ventricular e
xtrasystole, atrial fibrillation and flutter,and various mixed disturb
ances of cardiac rhythm and conduction. Cardiac arrhythmias and conduc
tion disturbance with prolonged Q-T interval were found to be precurso
rs of asystole in 84.8%.
