INTRODUCTION

Attention should be directed to some of the characteristics of interpolated contractions of the heart, particularly as they affect the radial pulse, since at times this type of cardiac irregularity is confusing.

An interpolated beat is a premature contraction of the ventricles which is not followed by a compensatory pause and does not disturb the dominant rhythm of the heart. It is impossible for auricular beats to be interpolated, because auricular premature beats are bound to disturb the dominant rhythm. It is also impossible to have interpolated beats in a case of complete auriculoventricular heart block, because here the dominant rhythm is ventricular, and so it, too, would be disturbed. Dresbach and Munford¹ state that interpolation in a case of Stokes-Adams' disease was reported by Lichtheim in 1905, but such a phenomenon is very unlikely. Inasmuch as interpolated beats can be no other than ventricular and must be premature, . . . [Full Text PDF of this Article]
