3.What can HRV do?
By analyzing the differences when the heart beats each time and having timely access to health information, HRV can be used for stress recovery. Studies have shown that heart rate variability can detect coronary heart disease, hypertension, and heart failure. In particular, the prognosis of cardiovascular disease will continue and should be monitored. Controlling the changes in the heart may prevent the recurrence of deterioration.
As shown in the picture to the left, by collecting the JJ interval data in the BCG graph (or the RR interval in the ECG/EKG graph or the PP interval in the PPG graph), the Lorenz plot is obtained. Darma can roughly judge whether a person has a sinus heart rate or supraventricular and ventricular arrhythmias by the Lorenz plot.
