Arrhythmia on Holter ECG and health status in elderly Russians
Europace Supplements, 7:S3, S29 (2005)
The goal was to examine the significance of arrhythmias in a sample of epidemiological cohort of the elderly Russians. 185 individuals (150 men and 35 women aged 67-87) underwent ambulatory 24-h Holter monitoring (MT-200, Schiller AG). Relationships between arrhythmia, health outcomes, and biomarkers were estimates by regression models controlled by age and sex. 63% participants had supraventricular couplets, 48% - nonsustained supraventricular tachycardia (NST), 10% - nonsustained ventricular tachycardia (NVT) with prevalence in men (p<.05), 4% - atrial fibrillation, and 13% - synoatrial block. High prevalence of supraventricular premature beats and NSVT are associated with worse self rated health (p<.06) and HDL (p<.02). High prevalence of ventricular premature beats and NVT are associated with number of reported diseases (p<.02) and Cohen´s Stress score (p<.04). No association with heart diseases, diabetes, HRV parameters, blood pressure, cholesterol, cortisol, norepinephrine, and epinephrine were found. Arrhythmias are frequent in elderly Russian population, characterized by higher mortality compared to other countries. SV arrhythmia is associated with worth perceived health; NVT is associated with higher stress. Role of arrhythmia for all cause mortality should be studied further.
