title: [Influence of heliometeofactors on sympathic and parasympathic activity as shown by analysis of cardiac rhythm variability in patients with ischemic heart disease and paroxysmal atrial fibrillation].
abstract: Dynamics of heart rhythm variability (HRV) according to 24-h Holter monitoring of ECG was studied in patients with chronic IHD with paroxysmal cardiac fibrillation (PCF) and controls in response to unfavourable medical weather types and high geomagnetic activity. In unfavourable meteorological conditions IHD patients with PCF show attenuation of a general effect of autonomic nervous system on heart rhythm, changes in correlation of sympathetic and parasympathetic activity. Shifts to relative sympathicotony, parasympathicotony or absence of parasympathicotony or sympathicotony predominance were recorded.
