The circadian, circaseptenal and circaannual occurrence of supraventricular paroxysmal tachycardias (SVPT) were examined in patients addressing an Emergency Department. Sixty-one patients, 22 men and 39 women aged 48.3+13.0 y, were eligible and investigated during a solar year. Cosinor method indicated a significant circadian SVPT variation, with an acrophase at about 6 p.m. A similar periodicity was also detected in supraventricular premature beat prevalence (acrophase at 3 h 31 min), concordant with heart rate peaking. Monday was the most frequently affected day, while the circa-annual analysis disclosed a peak in summer and autumn. Our findings provide further evidence that SVPT shows the highest occurrence during daytime, in possible connection with adrenergic influence. Moreover there are clues that cyclic stressors, e.g. the ones connected with working-activity resumption or climate influence, may partly condition SVPT appearance during the week or the year. |
