Heart Rate Variability (HRV) analysis - Arrhythmic risk stratification
Heart Rate Variability (HRV) analysis consists in the measurement and analysis of heart rate oscillation on a series of consecutive heartbeats for a variable observation period.
HRV is a parameter that can be estimated and analyzed through Dynamic Holter ECG monitoring.
Heart Rate Variability analysis allows to evaluate the activity balance between the sympathetic and parasympathetic nervous system and to deduce information on the risk of cardiac arrhythmias.
A high variability of the heart rhythm characterizes a healthy individual with efficient mechanisms of regulation of the autonomic nervous system.
While, a low variability of the heart rhythm is often an indication of an abnormal and insufficient adaptation to external factors with consequent reduced physiological function.
In patients with a history of myocardial infarction, a reduction in HRV (expression of increased sympathetic tone) has frequently been associated with an increased risk of sudden arrhythmic death.
The HRV analysis has no contraindications.
The HRV analysis has no risks.
The execution of this exam does not include preparation rules.
HRV is measured during Dynamic Holter ECG monitoring.
- A specially trained technician first attaches the electrodes to your chest.
- Once the electrodes are in place, the technician helps you put the Holter monitor on and explains how to take care of it.
- The technician will show you how to keep a diary of your activities and symptoms during the test. It’s important to keep an accurate diary.
