[Rhythmic and conductive disorders in the acute stage of cardiac infarct].

Rhythm and conductive disturbances were established in 170 (63,8%) out of 266 patients with fresh cardiac infarction, in the greatest part with prophylactically applied lidocain i.m. With age advancing a growth in their incidence is established but no statistical difference between the age groups 20-59 and 60-90 was found. Rhythm disturbances are found more frequently in women (81,6%) as compared with the men 58,7%) while the incidence in patients with posterior (62, 5%) and anterior (65, 7%) infarction is the same. Th-disturbances due to electrical instability and failure are more frequent in anterior infarction. Statistical difference (P less than 0,001) was established concerning the rhythm disturbances in patients with heart failure and without it, with a prevalence of sinus tachycardia, auricular fibrillation, ventricular extrasystoles, ventricular tachycardia and bundle branch block. The timely diagnosis and the treatment with medicaments led to the restoration of sinus rhythml in 79 out of 94 disturbances and with electrical shock in 12 out of 16. Parallelly with the classica netirhythm medicines (chinidine and procainamid), newer ones are used as tachmalin, lidocaine, abta-blockers, sympaticomimetics and temporary intracardial electric stimulation.
