[Dynamic electrocardiographic evaluation of the circadian rhythms of the ectopic ventricular beats in healthy and cardiopathic subjects].
The 24 hour study was carried out on 34 subjects, 17 cardiopathy 13 male and 4 female, mean age 56 +/- 14) and 17 normal (10 male and 7 female, mean age 41 +/- 18) with, on average, over 30 PVC/h in the dynamic ECG: no statistically significant difference in mean PVC/h was recorded between the two groups. Single cosinor analysis demonstrated a statistically significant circadian rhythm (p less than 0.05) in 11 cardiopathic (64.7%) and 13 normal subjects (76.4%). Population mean cosinor failed to demonstrate a significant rhythm in either of the two groups. Results suggest that personal circadian rhythms should be studied to identify the most appropriate antiarrhythmic treatment.
