Abstract

We present a case of redo atrial fibrillation (AF) ablation for pulmonary vein reconnection. In mapping of posterior wall of left upper pulmonary vein (LUPV) with HD grid, a new and unique multipolar mapping catheter, it demonstrated presence of local electrocardiogram signals (EGM). But during mapping with the Tacticath ablation catheter, these signals were not visible. Nevertheless, ablation at this point resulted in isolation of LUPV. The unique mapping technology offered by HD grid mapping catheter may enable us to discover local EGM not otherwise visible in conventional bipole parallel recordings, to have more accurate maps and deliver for effective therapies.

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.
