How a Watch was used to Discover Heart Rate Variability (HRV) & How it’s Discovery has Led to Managing Wellness & Health.

Variability is the law of life… (Wiliam Osler, Physician and educator, 1849-1919 (Olser, 1903, p.327).

The Rev. Stephen Hales (1733) was credited to be the first individual to notice that pulse varied with respiration via a watch with a second hand that could be paused, also known as the ‘Physician’s Pulse Watch”.

The first recording of RSA (Respiratory Sinus Arrhythmia, was conducted by Carl Ludwig in 1847.

The year, 1895 brought advanced insight and awareness into Heart Rate Variability (HRV) with the introduction of ECG (electrocardiogram)...

What are Those Wires that Hug the Heart?

Have you ever seen a movie, TV show, or commercial where a person is in a medical facility with wires attached to his chest? A fancy medical machine and doctor are usually nearby, accompanied by bleeps and bloops – sounds that mimic those of an EKG.

You’ve probably guessed before that these wires are helping doctors determine something.

But what?

Those wires and the machines you’ve wondered about are part of something called a heart rate variability (HRV) test. Today, the test is mostly used as a preventative medical measure that determines the consistency of someone’s heart rate during exercise. If the heart responds well to different physical variables, the person is said to have a decreased heart variability...

Heart Rate Variability: The Most Reliable Indicator of NAD

Image of: HRV measurement and EKGTo understand why heart rate variability (HRV) is incredibly useful for preventing disease and early mortality, it’s important to know exactly what HRV and Nonspecific Adaptation Deficit (NAD) are.  If you’re a medical professional, you may already know what each of these are and the connection they have to one another.  However, if you’re new to health monitoring or exploring new services for your private practice or medical center, HRV and NAD are worth exploring

What is Heart Rate Variability?

There’s no secret to the basic concept of HRV.  It’s simply the variation of heart beat intervals and the measurement of the succession of these variations.  Modern health monitoring equipment like the critical care test is used to produce a comprehensive and user-friendly output of informatio...
