Atrial flutter.
was attempted in eight patients with drug refractory type I atrial flutter. In seven of eight patients, a zone of prolongation and fragmentation of the endocardial electrogram was found in the low posterior part of the right atrium. Entrainment of the atrial flutter by high right atrial pacing was accompanied by local recording of second-degree regional block in several atrial sectors but never...
متن کاملMapping the conversion of atrial flutter to atrial fibrillation and atrial fibrillation to atrial flutter. Insights into mechanisms.
It is not generally believed that there is a relation between atrial flutter, thought to be due to a single reentrant circuit, and atrial fibrillation, thought to be due to simultaneously circulating multiple-reentrant wave fronts. However, there are many reasons to suggest that these rhythms are more closely related than previously thought. To test the hypothesis that the length of an area of ...
متن کاملElectrical conversion of atrial flutter to atrial fibrillation. Flutter mechanism in man.
If human atrial flutter is due to re-entrant excitation, depolarization as well as repolarization must continue throughout the entire atrial cycle. It follows that the atrial vulnerable period for inducing atrial fibrillation is also continuous rather than discrete. This hypothesis was examined during cardioversion of I33 patients with atrial flutter who received 280 low-energy shocks. A compos...
متن کاملCharacterization of Atrial Flutter
Studies were performed using bipolar atrial wire electrodes to record atrial electrograms and to pace the atria in 27 patients who developed atrial flutter after open heart surgery. Two types of atrial flutter, classic or type I atrial flutter, and type II atrial flutter, were identified. Both types of atrial flutter were characterized by uniformity of the beat-to-beat atrial cycle length, morp...
متن کاملCongenital atrial flutter.
Atrial flutter in infants is rare (Keith, Rowe, and Vlad, 1967) and was first reported by Lewis (1915) in an infant of 3 months. Carr and McClure (1931) reported atrial flutter in a newborn infant in whom the cardiac irregularity was noted occasionally before birth and in whom the heart rate and rhythm returned to normal on the 10th day after birth. Fetal tachycardia in such a case can lead to ...
