Second, find your heart rate reserve: Subtract your RHR from your MHR. Men should use the Inbar formula (205.8 – [0.685 x AGE]) for this; women can use either Inbar or the Gulati formula (206 – [.88 x AGE]). So, a 30-year-old man with a resting heart rate of 60 BPM would...

Low heart rate variability (HRV) has been proposed as a marker of a number of pathophysiologic conditions, including increased risk of mortality 1, 2, 3, 4, 5, 6. Cutpoints for increased risk of mortality also have been proposed 2, 3, 7. However, the use of HRV for predictive purposes...
Heart Rate:Heart rate refers to the number of times the heart contracts (i.e., beats) each minute. A normal heart rate is considered to be between 60 to 100 beats per minute. Tachycardia refers to a heart rate faster than normal, and bradycardia refers to a heart rate slower than ...
