What are the differences between “RVOT” Ventricular tachycardia and ARVD related VT *

Posted Nov 06 2012 12:40pm
A young man with   VT  (LBBB morphology ) and  apparently normal heart by   echocardiogram  is  a  real  diagnostic challenge .
Here is a comparison  of  the two  closely mimicking  entities. RVOT VT and ARVD .
(Caution : In  the traditional medical teaching system , we are often taught to differentiate  two closely related  entities.Our brain also loves to look things in either black or white . Realise , medical science always brings  surprises . There can be significant overlaps between the very entities we want to differentiate.Bear that in mind)

*RVOT- Right ventricular outflow tract. ARVD/ARVC -Arrhythmogenic  right ventricular dysplasia /cardiomyopathy
