In 26 patients (65-80 yr) with low risk of sudden death, the circadian rhythm of spontaneous ventricular arrhythmias was analyzed, throughout 72 h, by the Holter monitoring method. The prolonged ECG monitoring is indispensable to evaluate the real necessity of an antiarrhythmic therapy and to establish the therapeutic approach. Premature ventricular complexes (PVC): isolated, couplets and runs of ventricular tachycardia have been considered. The isolated PVC showed uniform distribution throughout 24h, with higher frequency/hour ratio (f/h) in females. Couplets and runs showed circadian diurnal distribution with higher f/h ratio in smokers and males. After analysis of the results, the patients were additionally subdivided into smokers and non-smokers. Since smokers showed a diurnal distribution of all kinds of arrhythmias, antiarrhythmic drugs whose pharmacological peak corresponds to the distribution peaks of arrhythmias were proposed. Non-smokers could be divided into two groups: a) patients with isolated extrasystoles which did not show a circadian rhythm of arrhythmias and who must be treated with retard-drugs, which give protection throughout 24h; b) patients with runs or couplets of PVC showing a circadian rhythm of arrhythmias and who must be treated with drugs whose pharmacological peak corresponds to the distribution peaks of arrhythmias.
