0121: Heart rate variability in elderly ischemic patients with ventricular arrhythmias - 12/02/16
Résumé |
Background |
Heart rate variability and autonomic nervous system dysfunction have a recognised value in the assessment of the prognostic of heart disease and it is well known that variability decreases with age and in heart failure or ischemic patients, as a predictor for worsen outcome and for an increase in mortality and morbidity.
Materials and methods |
We retrospectively investigated 12 lead Holter ECG monitoring in the past 2 years for ischemic patients aged 50 or older who had ventricular arrhythmias. We included in our observational study 25 patients, 16 women and 9 men with a mean age of 64,71±9,09. For each of the participants we evaluated the heart rate variability parameters: SDNN, SDANN, MSSD, pNN50.
Results |
Our analysis revealed that there is a good correlation between the number of ventricular escape beats on a 24 hours monitoring and the heart rate variability parameters SDNN (y=8,7266x – 757,02 R2=0,8171) and rMSSD (y=8,6658x – 65,347 R2=0,6395).
Conclusions |
The results may be a starting point for future research for improving the prognostic in elderly with cardio-vascular disease, taking into consideration that both parameters (heart rate variability and ventricular arrhythmias) may be influenced and improved either by adequate physical activity or by antiarrhythmic drugs with strong implications in deciding for primary and secondary prevention.
