    Representative example of 24-hour 3-dimensional return maps in a control subject (1) and a patient with Chagas disease and normal left ventricular function (2). Three-dimensional distributions (a) and contour curves (b). P1 was measured at maximum density along the plane depicted; P1 = (100 – 2 · Mean slope); Mean slope = Tangent of the angle θ. P2 = Maximal longitudinal range and P3 = Maximal transversal range.
