Right ventricular mechanical dispersion is related to malignant arrhythmias: a study of patients with arrhythmogenic right ventricular cardiomyopathy and subclinical right ventricular dysfunction.
AIMS We evaluated if right ventricular (RV) mechanical dispersion by strain was related to ventricular arrhythmias (VT/VF) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and if mechanical dispersion was increased in so far asymptomatic mutation carriers. METHODS AND RESULTS We included 69 patients, 42 had symptomatic ARVC and 27 were mutation positive asymptomatic fam...
متن کاملArrhythmogenic Right Ventricular Cardiomyopathy
Arrythmogenic right ventricular (RV) cardiomyopathy (ARVC) is a cardiomyopathy characterized pathologically by fibrofatty replacement primarily of the RV and clinically by life-threatening ventricular arrhythmias in apparently healthy young people. The prevalence of the disease has been estimated at 1 in 5,000 individuals, although this estimate will likely increase as awareness of the conditio...
متن کاملArrhythmogenic right ventricular cardiomyopathy.
Arrhythmogenic right ventricular cardiomyopathy (ARVC) has evolved from postmortem pathology at to a diagnosable clinical condition, and holds promise for definitive genetic diagnosis. Its prevalence is between 1/1,000 and 1/5,000, with 10% of deaths occurring before age 19 and 50% before age 35. When analyzed against age-specific norms, the electrocardiography (ECG) and signal-averaged ECG (SA...
متن کاملVentricular Arrhythmias in Arrhythmogenic Right Ventricular Dysplasia
Ventricular arrhythmias due to ARVD and right ventricular outflow tract arrhythmia (RVOTA) share the same left bundle branch block pattern with inferior axis on the ECG. The former has a more malignant course while the latter has a better prognosis and is more amenable to radiofrequency catheter ablation. Hence differentiating them is of utmost clinical importance in the management of these pat...
متن کاملElectrocardiographic comparison of ventricular arrhythmias in patients with arrhythmogenic right ventricular cardiomyopathy and right ventricular outflow tract tachycardia.
OBJECTIVES The purpose of this study was to evaluate whether electrocardiographic characteristics of ventricular arrhythmias distinguish patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) from those with right ventricular outflow tract tachycardia (RVOT-VT). BACKGROUND Ventricular arrhythmias in RVOT-VT and ARVD/C-VT patients can share a left bundle branch block/...
