Varicella myocarditis presenting with unusual ventricular arrhythmias.
A 10-year-old boy with varicella developed syncopal episodes caused by runs of self-terminating ventricular tachycardia and ventricular fibrillation. These arrhythmias were thought to be caused by varicella myocarditis and were resistant to most common antiarrhythmic agents. Continuous electrocardiographic recording and analysis proved extremely useful in the management of this case. Mexiletine...
متن کاملMyocarditis Presenting with Ventricular Arrhythmias: Role of Electroanatomical Mapping-Guided Endomyocardial Biopsy in Differential Diagnosis
Myocarditis is defined as a disease characterized by myocardial inflammation associated with myocyte necrosis. It can be caused by infections, autoimmune response primarily affecting the myocardium or by systemic autoimmune or inflammatory disorders (Aretz et al., 1986). Viral infections are the most frequent cause and account for the vast majority of cases in North America and Europe (Cooper, ...
متن کاملIncidence, Risk Factors, and Outcome of Life-Threatening Ventricular Arrhythmias in Giant Cell Myocarditis.
BACKGROUND Ventricular tachyarrhythmias are characteristic of giant cell myocarditis, but their true incidence, predictors, and outcome are unknown. METHODS AND RESULTS Our work involved 51 patients with giant cell myocarditis (35 women) aged 52±12 years. Their medical records were reviewed for history, results of laboratory and imaging studies, and occurrence of serious cardiac events, inclu...
متن کاملIncidence, Risk Factors, and Outcome of Life-Threatening Ventricular Arrhythmias in Giant Cell Myocarditis
Idiopathic giant cell myocarditis (GCM) is a rare but serious heart muscle disease whose pathogenesis is insufficiently known but commonly attributed to T cell–mediated autoimmunity. The early international registry studies of the 1990s characterized GCM as a disease that mainly involves young and middle-aged individuals and is deadly to the extent that 50% of the diseased either die or undergo...
متن کاملVentricular Arrhythmias.
Ventricular tachycardia (VT) is the most common form of wide complex tachycardia and is associated with a high mortality rate. Electrocardiographic analysis remains paramount in diagnosis and helps to direct therapy. Antiarrhythmic agents, although effective in reducing arrhythmia burden, have never demonstrated a mortality benefit. The implantable cardioverter-defibrillator aids not only in th...
