title: [The double ratio as an index of the normal functional organization of the human heart cycle at rest].
abstract: The three-phase temporal dynamic structure of the cardiac cycle of man was assayed with the ECG curves using the double ratio. The magnitude of the double ratio is virtually permanent for normal men at rest, being independent of the sex or age. The double ratio within the limits 1.20 +/- 0.03 is regarded as criterion of normal dynamic organization of the cardiac cycle.
