Abstract

Catheter ablation is a widely used treatment for atrial fibrillation. Gastric hypomotility due to periesophageal vagal plexus injury is a consequence of the extracardiac penetration of ablative energy. Some affected patients develop severe gastric dilatation requiring hospitalization. However, most previous reports have stated the cause of the subject's condition to be "unknown" or described the symptoms using obscure terms, such as "paralytic" or "gastroparesis." For example, one report stated that a few sites of severe gastric dilatation were secondary to "pyloric spasms;" however, no illustrations were provided in the paper. "Superior mesenteric artery syndrome" is a suspected cause of such dilatation.

Atrial Filbrillation

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

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.
