Abstract

Atrioventricular nodal (AVN) ablation and right ventricular (RV) pacing is recommended for refractory atrial fibrillation (AF) and tachycardia-bradycardia syndrome. Three AF patients (mean age 83, range 79-89 years) underwent AVN ablation and transvenous leadless pacemaker Micra™ implantations using the same venous access without anticoagulation interruption. Satisfactory pacing 0.59 (0.50-0.63) V at 0.24 ms and sensing 11.2 (6.3-15.6) mV were achieved within 1-3 deployments. There were no vascular complications nor device dislodgment. Durable pacemaker parameters and VVIR pacing were achieved. Combined AVN ablation and leadless pacemaker implantation is feasible and safe, and avoids pacemaker pocket hematoma and bleeding complications in patients on uninterrupted anticoagulation.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
