Cardiac arrest in an adolescent with Uhl’s anomaly: Two unusual cardiac arrhythmia mechanisms
نویسندگان
چکیده
Introduction Uhl’s disease is a rare congenital cardiac anomaly characterized by partial or complete absence of the right ventricular free wall myocardium, which is replaced by fibroelastic and adipose tissue. Complications that result can be divided into either right ventricular dysfunction with congestive heart failure, or arrhythmias. While ventricular arrhythmias predominate, there are case reports of atrial flutter, intra-atrial reentry tachycardia, atrioventricular (AV) block, and bilateral bundle branch block. Sudden cardiac death has been reported in patients with Uhl’s anomaly. Herein we report an adolescent patient with out-ofhospital cardiac arrest with 2 unusual arrhythmia mechanisms. What are the mechanisms for these 2 arrhythmias?

Objective: Survival-to-discharge rates following in-hospital cardiac arrest (IHCA) patients remain significantly low. The use of initial documented cardiac rhythm as predictor of Survival-to-discharge is still unclear. This study aimed to assess whether the initial documented rhythm can be used as a predictor of survival-to-discharge following IHCA in an emergency department of the tertiary car...

Misuse of stimulants similar to amphetamine is a universal problem. These stimulants cause many complications in their abusers. However, myocardial infarction is rarely reported as a complication of amphetamine abuse. Herein, we report a man aged 42 years presented at the Emergency Department with the chief complaint of acute dyspnea following ice inhalation without history of dyspnea. Within t...
