Thirty-eight patients with drug refractory and symptomatic AF, underwent APT in eight ...
Overdrive atrial pacing can help avoid development of AVNRT during ablation and allow for monitoring of anterograde AV conduction. However, junctional beats will not be seen during overdrive atrial pacing. AV block may be due to ablation injury of the compact AV node or may reflect underlying ...
sinus node dysfunctionIn patients needing a pacemaker (PM) for bradycardia indications, the amount of right ventricular (RV) apical pacing has been correlated with atrial fibrillation (AFib) and heart failure (HF) in both DDD and VVI mode. RV pacing was linked with left ventricular (LV) dys...
Atrial and ventricular pacing may be needed due to atriotomy scars or atrial arrhythmia ablations with subsequent sinus node dysfunction or due to prior ventricular septal defect repair or altered His-purkinje anatomy due to their underlying defect [3,4]. Traditionally, transvenous pacemaker ...
The impact of a right bundle branch block (RBBB), inadvertently created prior to complete ablation of the atrioventricular (AV) junction, on the intrinsic subsidiary pacemaker function was investigated. In 31 patients suffering from intractable supraventricular tachyarrhythmia, catheter ablation of the AV...
For dogs of all ages, the pattern of spread over the septum was greatly affected by the location of the pacemaker site simulating a high or low sinus node position. For all sinus pacing positions, wave fronts spread over the crista terminalis to form a posterior input to the AV node, ...
47 This is especially true for patients with heterotaxy syndrome (in whom AV node location can be ambiguous) or those with defects of the AV canal septum (who do not have a triangle of Koch). Successful SP ablation can still be accomplished safely in most cases if proper techniques and ...
Reports on the significance of ablation of the atrioventricular node and pacemaker insertion for severe atrial fibrillation. Improvement of the left ventricular function; Decline of the survival rates upon treatment; Safety of the procedure for atrial fibrillation.Zolot...
After a follow-up of 2.1±2 years, pacemaker implantation was implanted in 15 patients, 1 patient with traumatic AVB3 aged 81 years, 5 patients with AVB3 during ablation, 2 with permanent AVB3 (0.2%) and 3 with transitory AVB3 and 9 patients without AVB during ablation. In these last ...
38.8% of all patients with permanent atrial fibrillation have more than one AV nodal pathway; 6.4% of all patients with atrial fibrillation would benefit from an ablation of AV nodal pathways with shorter refractory periods for reduction of the heart rate. 展开 ...
