The Human Heartbeat

A peaceful heartbeat is said to beat in a Phi rhythm

A normal human heart beats in a phi rhythm, with the T point of a normal electrocardiogram (ECG or EKG) falling at the phi point of the heart's rhythmic cycle.

Prominent parts of the ECG 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.

While heartbeats vary, some believe that a heartbeat that reflects this perfect phi relationship represents a state of being that is one of health, peace and harmony.

EKG's resemble 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:
