  • Healthy Heartbeat

    Over the past two months I have been doing a lot of reading about "Heart Rate Variability", the variation in beat-to-beat intervals of the heart.

    Prior to that, I knew that most athletes had a lower resting heart rate than sedentary folks; however I had assumed that a resting heart rate was strong and steady - That is absolutely NOT the case.

    A healthy heart has a great deal of variability (oscillating up and down with inhalation and exhalation) and exercise tends to improve (increase) HRV unless you are in an overtrained state.

    Just thought I would pass this along since it was new information to me.

      I read on Art DeVany's site a long time ago that the heart beats steadily like a metronome on two occasions: during long-distance running and right before cardiac arrest. Hrmmm..
      You lousy kids! Get off my savannah!

        Given the strong correlation between low HRV and heart disease, I would love to know why doctors do not look at HRV instead of cholesterol...

          Well that explains a lot... I was wondering if the slow but not regular heartrate was a good or bad sign, and now I know.
          Thanks!

            Heart Rate Variability has a lot of research correlating it to many benefits such as increased willpower, motivation, lower stress etc.

            My own experimentation has shown that Intermittent Fasting seems to have the biggest impact on it for me so far - increasing baseline by around 10 points of lnRMSSDX20.

            Some HRV interviews digging into details of the measurement:

                This is really interesting. Do you have some good links I can point my cardio friends?
