The Human Heartbeat

A peaceful heartbeat is said by some to beat in a Phi rhythm

The prominent parts of an electrocardiogram (ECG or EKG) are the P wave, a deflection caused by the current originating in the atrium; the QRS complex, showing the passage of the electrical activity into the ventricles; and the T wave, as the ventricles reset themselves.  The electrocardiograms (ECG or EKG) of human heartbeats vary considerably depending on a variety of factors. 

Heartbeat2000 seeks to study the relationships between the physical heart and the spiritual heart, that is the soul, of human beings.  The views presented there suggest that a heartbeat that produces a phi relationship in the T point of the ECG represents a state of being that is one of health, peace and harmony.

While this is an area that still needs research and scientific corroboration, it is an interesting perspective on another potential appearance of phi in life.

EKG's show a resemblance to the Fibonacci Convergence

As explained on the Fibonacci Series page, the ratio of each successive pair of numbers in the Fibonacci series (0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, . . .) converges on phi (1.618. . .) as you go higher in the series.

The first numbers in the series give an approximation of phi.  For example:

Curiously, if you graph these approximations of phi in the series above you get the chart below, the first part of which bears a similarity to the EKG pattern of the human heartbeat.

Insight on relationship of Fibonacci Convergence contributed by Robert Bartlett, who notes:

The law of his (e.g., David's) God is in his heart; none of his steps shall slide.  Psalms 37:31
