Resting Heart Rate, Heart Rate Variability and Electrocardiogram Changes In Chronic Alcoholics
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 2
Abstract
Aim: Alcohol use is causing damage to the health. The damage may be physical or mental. Recent studies strongly suggest that long-term, alcohol abuse may have powerful implications on cardiovascular health. However, very few studies have focused on the association between long-term alcohol drinking and resting heart rate, Heart rate variability and electrocardiogram changes at rest in these individuals. Thus, the present study was conducted to establish the electrocardiogram changes, heart rate and heart rate variability in chronic alcoholics at rest and to compare the changes with that of non-alcoholic controls. Methods: The study group consists of Fifty men, aged between 30-50 years with alcohol intake for more than 5 years of duration, without any known cardiac illness. Similarly, Fifty non-alcoholic individuals of the same age, sex and anthropometrically matched group constitute the control group. Resting heart rate was recorded while heart rate variability and ECG were monitored and recorded by using ECG –DYNATRAC system. Statistical analysis was done by using student‘t’ test. Result: In the present study, there was a significantly high resting heart rate (tachycardia) and decreased heart rate variability in alcoholics compared to non-alcoholics.ECG in them showed significant decrease in RR interval. However, all other ECG waves, intervals and QRS frontal axis were unchanged in them compared to controls. Conclusion: Long-term alcohol intake has deleterious effects on cardiovascular functions as it leads to increased resting heart rate, decreased HRV and ECG changes. These findings may be an early indicator of the ‘alcohol abuse’ on body system, especially on the cardiovascular system
