Auriculo-ventricular Rhythm.
assumes control over the ventricles. When this happens, two types of auriculo-ventricular rhythm may arise. One is called A-V nodal rhythm and is recognized by the inverted P waves, which are as a rule either abnormally close to the QRS complex or may follow it. The second type of auriculo-ventricular rhythm is known as A-V dissociation, characterized by the rate of the ventricular contractions...
متن کاملLeft ventricular approach for recording His bundle potential in man.
The electrical potentials of the His bundle (HB) were recorded from the left ventricular endocardial surface in 28 patients ranging from 16 to 63 years of age. In 14 of the patients the left bundle branch (LB) potentials were also obtained. Placement of a bipolar electrode catheter tip toward the interventricular septum, right at and also 1 to 2 cm below the aortic valve, resulted in stable rec...
متن کاملFreezing at the His Bundle
Prior to 1980, the only method to treat cardiac arrhythmias besides anti-arrhythmic drug therapy was open-heart surgery, that involved either dissecting or freezing the arrhythmic focus with a hand-held metal probe. Soon thereafter, early reports of percutaneously performed cardiac ablation were published that marked the beginning of a new era in the field of cardiac electrophysiology (EP). As ...
متن کاملHis Bundle Refractoriness.
Multiple points of instruction discussed practically in the context of a challenging case make for a memorable learning experience. In this installment of Teaching Rounds in Cardiac Electrophysiology, Nayyar et al elucidate the unique findings and analysis in such a manner and take us through to diagnosis and a treatment plan that eliminated arrhythmia without having to ablate all of the abnorm...
متن کاملHis bundle rhythm.
SUMMARY Traditionally the site of impulse formation in so-called A-V nodal rhythms has been considered to be within the upper, middle, and lower portions of the A-V node. In this study, evidence obtained supports the concept that the His bundle and not the A-V node is the pacemaker site in nodal rhythms. His bundle activity was recorded in clinical cases of nodal rhythms and A-V dissociation by...
