Abstract

A 2-year-old boy was diagnosed with TARP syndrome and underwent surgery for tetralogy of Fallot. He developed fever and had an acute abdomen. After 12 hours, atrial tachyarrhythmia (300 beats/min [bpm]) occurred. After nine administration of adenosine and two cardioversions, it relapsed promptly. Landiolol (10 μg/kg/min) was administered until the heart rate decreased to 270 bpm, and cardioversion was performed until sinus rhythm was normal. Exploratory laparotomy revealed small bowel volvulus. Systemic inflammation causing an acute abdomen may be associated with atrial tachyarrhythmia in postoperative tetralogy of Fallot. We speculated that landiolol lowered the defibrillation threshold of the atrium.

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.
