Value of the signal-averaged electrocardiogram in arrhythmogenic right ventricular cardiomyopathy/dysplasia

Value of the signal-averaged electrocardiogram in arrhythmogenic right ventricular cardiomyopathy/dysplasia.

BACKGROUND Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an inherited disease that causes structural and functional abnormalities of the right ventricle (RV). The presence of late potentials as assessed by the signal-averaged electrocardiogram (SAECG) is a minor task force criterion. OBJECTIVE The purpose of this study was to examine the diagnostic and clinical value o...

Signal-averaged electrocardiogram in patients with arrhythmogenic right ventricular cardiomyopathy and ventricular arrhythmias.

OBJECTIVE The aim of the study was to assess the prevalence, sensitivity, specificity and predictive value of the signal-averaged ECG in patients with arrhythmogenic right ventricular cardiomyopathy and different forms of ventricular arrhythmias. METHODS The signal averaged ECG in 138 patients and 146 healthy subjects (control group), using a three bandpass filter system (25-250, 40-250, 80-2...

Diagnostic value of isoproterenol testing in arrhythmogenic right ventricular cardiomyopathy.

BACKGROUND Although the Task Force Criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) have recently been updated, the diagnosis remains challenging in the early stages. The aim of this study was to evaluate the diagnostic value of β-adrenergic stimulation in ARVC. METHODS AND RESULTS We evaluated 412 consecutive patients (213 men, age 41.5±16 years) referred for premature ven...

Correlation Between Signal-Averaged Electrocardiogram and the Histologic Evaluation of the Myocardial Substrate in Right Ventricular Outflow Tract Arrhythmias

Signal-averaged electrocardiogram in Ebstein's anomaly.

We sought to establish pathogenetic links between electrophysiology, histopathology, and ventricular tachyarrhythmias in patients with Ebstein's anomaly. The atrialized right ventricle (ARV) is the site of mechanically inducible ventricular tachyarrhythmias, but relations between the arrhythmogenic substrate, the type of tachyarrhythmias, and the trigger(s) have not been established. This study...
