Learning Objectives

1. To study the basics of Heart Rate Variability (HRV) and its components.

2. To learn the physiology of HRV and its relationship with the Autonomic Nervous System (ANS).

3. To introduce the recording of HRV signals using appropriate tools

4. To describe time-domain and frequency-domain HRV parameters (e.g., SDNN, RMSSD, LF, HF) and to calculate these metrics.

5. To interpret HRV patterns in different physiological and pathological conditions.
