Der Einfluss der Extrasystole auf die Dynamik des Herzens

Clinical Value of the Polygraphic Tracing in the Study of the Sequence of Events During Cardiac Contraction

“…Atypical spreading of the electrical impulse in the heart muscle. Atypic conduction of an electrical impulse is invariably asso ciated with a prolongation of the deformation time, while the course of the subsequent components of cardiac contraction is regularly without any changes (bundle branch block, ventricular extrasystoles, complete atrioventricular block) (6,13,17,33,34,38). The prolongation of the deformation time corresponds up to a cer tain degree to the duration of the QRS complex in the electro cardiogram; thus it is mostly slightly more marked in the left bundle branch block, than in the right bundle branch block.…”

“…In clinical practice it was introduced and further developed by Blumberger (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17). During the last ten years this method in sev eral modifications was used by many investigators, especially in Germany.…”
