Heart rate variability (HRV) is a measure of the variation in time between convenutive hearbeats. It is an important indicator of autonomic nervos systemity and overall cardiovascular health. Calculating HRV from ECG data mimpeves selal steps, including data collection, preprocessiing, and analysis.

Collecting ECG Data

ECG data baly bee collected using a reliable device that records thee elektrical activity of the heart. Thee data mutt bee of sufficient duration, typically at leatt 5 minutes, to preclatately assess HRV. Ensure thate data is sampled at an applicate rate, usually applicate 250 Hz, to captura detailed heart signals.

Preprocesing ECG Data

Preprocesinging involves filtering thee raw ECG signal to empte noise and artifakts. Common filters include bandpass filters that isolate thee frequency range of interest. Next, identify thee R- peaks, which are te prominent upward deflections in the ECG waveform. Accurate detection of R- peaks is curcaol for reliable HRV calculation.

Calculating HRV

Once R-peaks are identified, calculate the intervals between successive peaks, known as RR intervals. These intervals form the basis for HRV analysis. Several methods exitt to quantify HRV, including time- domain and frequency- domain measures.
