Electrical Storm in Chagas Cardiomyopathy

This study of patients with Chagas heart disease (CHD) with an implantable cardioverter-defibrillator (ICD) for secondary prevention of sudden cardiac death sought to compare the characteristics of those with or without electrical storm (ES) during long-term follow-up. ES is a common problem in pati...

Description
Summary:This study of patients with Chagas heart disease (CHD) with an implantable cardioverter-defibrillator (ICD) for secondary prevention of sudden cardiac death sought to compare the characteristics of those with or without electrical storm (ES) during long-term follow-up. ES is a common problem in patients with CHD harboring an ICD, but data on clinical predictors and outcomes are limited. The authors retrospectively evaluated 110 patients with CHD with a mean follow-up of 1,949 ± 1,271 days. Demographic, clinical, arrhythmia characteristics, ICD treatment, and death data were collected. Descriptive statistics included mean ± SD and Fisher exact tests used for comparisons. A p value
