Participation of atrial specialized conduction pathways in atrial flutter.
The circus movement theory of flutter has been supported by numerous theoretical, experimental, and clinical studies, but there has been little consideration of the possible participation of the specialized conduction pathways of the atria. In the present work we have studied experimental atrial flutter in relation to the behavior of these pathways, in response to elevated potassium and to surg...
متن کاملAberrant atrial conduction.
I would like to make one comment regarding the paper entitled 'Aberrant Atrial Conduction' from the British Heart journal of April I972, by Edward K. Chung. In all of his examples of socalled aberrant atrial conduction he makes an assumption that the aberrant atrial impulse originates from the sinus. I am unable to ascertain from his article how he came to this conclusion. Most of his examples ...
متن کاملEctopic Atrial Automaticit and Conduction
Background. Previous studies have shown that class Ic antiarrhythmic agents are effective in suppressing ectopic atrial rhythms and accessory pathway conduction. Methods and Results. To explore the potential mechanisms for their effectiveness, we investigated the concentration-dependent effects of the Ic agent flecainide acetate (0.5 to 10 utg/mL) on atrial ectopic automaticity and exit conduct...
متن کاملVentriculo-atrial conduction in man.
Transvenous electrodes were placed in the right atrium and ventricle of 50 patients with heart disease and arrhythmias. The ventricles were paced at several rates, each in excess of the sino-atrial rate. An atrial electrogram and surface electrocardiogram were recorded simultaneously in each patient; utilizing strict criteria, the incidence with which 1:1 ventriculo-atrial conduction (VAC) coul...
متن کاملPathways of preferential arterial conduction.
Sir, In his reply to our earlier letter (1985; 53: 350) it seems to us that Dr T N James has misconstrued the point we wish to make. In our letter it is clear that when we speak of the division of the ventricular bundle branches we discuss the division of all the bundle branches. The relevant sentence is "if the tissue within the insulated sheaths is divided". Here we use the plural "sheaths" a...
