VENTRICULAR ESCAPEREPORT OF AN UNUSUAL CARDIAC RHYTHM IN A CHILD

Am J Dis Child. 1925;30(1):50-54. doi:10.1001/archpedi.1925.01920130056009
Abstract

Ventricular escape is described by Lewis1 as that condition in which the impulse formation in a new rhythm center (namely, the auriculoventricular node or the idioventricular center) exceeds the rate at which impulses are received at that center from outside, the heart responding in part or in whole to this new center. This set of conditions may conceivably arise either from a depression of the sino-auricular node or from an excitation of the new center in the ventricle.

With the increasingly widespread use of graphic methods in the study of the heart beat, many abnormalities of cardiac rhythm have been frequently and successfully investigated in the adult. This is probably less true of the arrhythmias of childhood. A report of an unusual cardiac rhythm in a child is presented here.
