[Assessment of heart rhythm in patients with dilated cardiomyopathy based on daily ECG monitoring data].
The quantitative and qualitative characteristics of arrhythmias were examined, using continuous 24-hour ECG monitoring, in 25 patients with dilatation cardiomyopathy. Supraventricular extrasystole was found in 100% of patients with the sinus rhythm, and ventricular extrasystoles, in 94% of patients, being most commonly associated with poor prognosis (polytopic extrasystoles in 84%, paired extrasystoles in 60%, and paroxysmal ventricular tachycardia in 40%). Disorders of atrio-ventricular conductivity were recorded in 47.6% of patients with the sinus rhythm, 23.8% of those showing a permanent 1st-degree block, and the rest, a transient block of the 1st--3d degree. It was demonstrated that arrhythmias could serve as a permanent sign of dilatation cardiomyopathy, being most commonly of a complex nature and associated with poor prognosis.
