Extrasystolic arrhythmias (EA) as the most prevalent cardiac rhythm disturbances are clinically valuable predictors in patients with various cardiovascular diseases. EA in some clinical situations tend to transform into paroxysmal high grade arrhythmias, which may be life-threatening. Autonomic effects, electrolyte, hormone and pharmacological influences exert extrasystolic activity of myocardium.
The study aimed to evaluate relation between lunar phase and EA occurrence during 24-hour ECG-monitoring in patients with different CVD, and to analyze correspondence between quantity of extrasystoles and time of ischemia, if it appeared during Holter monitoring.
552 patients, age (59.19±7.80) years underwent Holter monitoring using diagnostic appliances DX-AKM-03 ArNika and CARDIOSPY. Daily quantity of supraventricular extrasystoles (SE), paired and grouped SE, ventricular extrasystoles (VE), paired and grouped VE were counted after statistical elimination of extreme values (less then 700 SE/VE per 24 hours or more than 10 000 SE/VE per 24 hours). Correspondence between lunar phase and time, during which ECG-monitoring was carried out, was assessed.
Relation between SE occurrence and 1st quarter of the moon was found out. VE were more prevalent during 4th lunar phase. Correlation occurred between common quantity of VE and time of ischemia, SE quantities were irrespective.
