Is Mechanical Dispersion a Raven of Ventricular Arrhythmias?

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...

Mechanical dispersion by strain echocardiography: a predictor of ventricular arrhythmias in subjects with lamin A/C mutations.

of redundant collateral vessels. No pre-operative cardiac catheterization was performed. The 3D print model was available in the cardiac catheterization laboratory during percutaneous coiling of 2 of 3 known aortopulmonary collaterals. The third was found to be atretic as shown in Figures 1E and 1F. This process helped focus catheter-based intervention and reduced the amount of fluoroscopy time...

Dispersion of ventricular repolarisation: a marker of ventricular arrhythmias in patients with previous myocardial infarction.

OBJECTIVE To examine whether, in coronary patients after myocardial infarction, the dispersion of ventricular repolarisation measured through QT and JT intervals from a surface electrocardiogram could allow separation of those with ventricular tachyarrhythmias (VT) complicating their myocardial infarct from those without. DESIGN A retrospective comparative study. SETTING University hospital...

Ventricular 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...
