right atriumspeckle tracking echocardiographyPurpose Atrial fibrillation (AF) is relatively frequent in the postoperative period, and is associated with an increased frequency of adverse events. The role of right atrial (RA) volume and functions in the development of AF is unknown. In this study, ...
Objectives Left ventricular-right atrium (LV-RA) shunt (Gerbode defect), is a rare type of ventricular septal defect. The purpose of this study was to discuss the role of the echocardiography in LV-RA shunt in the perioperative period. Methods The clinical and echocardiographic characteristics of...
Effect of Right Atrial Isthmus Ablation on the Occurrence of Atrial Fibrillation: Observations in Four Patient Groups Having Type I Atrial Flutter With or ... The goal of this study was to test the hypothesis that the occurrence of atrial fibrillation (AF), in at least some patients with ...
The harmonious proportions of the atrium at the entrance lead through to a dramatic interior of fine fireplaces and painted ceilings. Palladio’s design is simple, clear and not over-crowded. The show has been organised on the same principles, according to Howard Bums, the architectural historian...
Blood pres- sure will be assessed in a seated position at the level of the right atrium, with the participant's back supported and uncrossed legs with both feet on the floor. A second separated measurement will be done after a 5-min seated rest period [61]. Anthropometry Subjects' ...
The diastolic pressure-volume relationship of the right ventricle, and to a lesser degree of the left ventricle, shifts downward following pericardiectomy. In dogs, the pericardium has been shown to limit maximal cardiac output. Some disease states associated with a rapid increase in total heart ...
Use of a valved conduit from right atrium to pulmonary artery for “correction” of single ventricle Circulation, 54 (1976), pp. 63-70 View in ScopusGoogle Scholar 7 Gonzales-Lavin L, Blair TC, Chi S, Sparrow AW Orthoterminal correction of coexisting d-transposition of the great arteries, ...
The AV node is not the pacemaker of the heart. The SA node is considered the pacemaker of the heart because it generates the electrical impulses of the heart. Where exactly is the AV node? The AV node is located near the bottom of the right atrium. Additionally, the AV node is located...
The proper expression and function of the cardiac pacemaker is a critical feature of heart physiology. The sinoatrial node (SAN) in human right atrium generates an electrical stimulation approximately 70 times per minute, which propagates from a conducti
We studied the contraction of the right atrium in an excised cross-circulated heart preparation. Atrial volume and instantaneous atrial pressure were measu... VK Lau,K Sagawa,H Suga - 《American Journal of Physiology》 被引量: 361发表: 1979年 Anisotropic Conduction Properties in Canine Atria Ana...
