Why the study?
Do specific electrocardiographic patterns help differentiate arrhythmogenic right ventricular dysplasia/cardiomyopathy from idiopathic right ventricular outflow tract ventricular tachycardia?

Specific baseline and arrhythmia ECG characteristics, such as prolonged QRS in lead I and multiple VT morphologies, are crucial for differentiating ARVD/C from benign RVOT-VT.
Ventricular arrhythmias in patients with ARVD/C are common. Differentiation between idiopathic ventricular tachycardia and arrhythmogenic right ventricular dysplasia is of utmost importance. Baseline sinus rhythm electrocardiography as well as electrocardiographic differences during ventricular arrhythmias (VT or PVCs) can be helpful in differentiating the two disease states. The pathological fibrofatty myocyte replacement in ARVD/C as well as ventricular arrhythmia origin are likely responsible for these differences.

Hoffmayer et al. (2012) conducted a review in Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) and Right ventricular outflow tract ventricular tachycardia (RVOT-VT). Electrocardiographic characteristics vs. RVOT-VT was evaluated.
