Differential Diagnosis
The differential diagnosis for the ventricular tachycardia due to ARVD include:
- Congenital heart disease
- Acquired heart disease
- Miscellaneous
- Pre-excited AV re-entry tachycardia
- Idiopathic RVOT ventricular tachycardia
Differentiating ARVD/C from RVOT VT
Ventricular tachycardia associated with ARVD/C may be difficult to differentiate from RVOT VT. Electrocardiographic clues that support the diagnosis of ARVD/C include multifocal and/or polymorphic ventricular tachycardia (VT) originating from the right ventricle, T wave inversions in the right precordial leads, slurred upstroke (≥55 ms) of the S wave in V1 to V3 leads, and the presence of an epsilon wave.
Differentiating ARVD/C from Dialted Cardiomyopathy
ARVD is distinguished from dilated cardiomyopathy by the greater degree of arrhythmogenicity. In dilated cardiomyopathy, although ventricular arrhythmia commonly occurs, it is rare in the absence of significant ventricular dysfunction. In contrast, ARVD is significantly associated with ventricular arrhythmia even in the absence of ventricular dysfunction. Furthermore, sudden cardiac death is the first clinical manifestation of the disease in more than 50% of probands with ARVD. Additionally, regional ventricular involvement and the presence of ventricular aneurysm, which are hallmarks of ARVD/C, argue against the diagnosis of dilated cardiomyopathy.
