BALDERRAMO, Domingo C.  e  CAEIRO, Andrés A.. Arrhythmogenic right ventricular dysplasia and sick sinus syndrome. Medicina (B. Aires) [online]. 2004, vol.64, n.5, pp.439-441. ISSN 0025-7680.

Arrhythmogenic right ventricular dysplasia (ARVD) involves primarily the right ventricle, and should be considered in young patients presenting with syncope, ventricular tachycardia, cardiac arrest or in adults patients with congestive heart failure. Atrial electrical abnormalities due to ARVD have been rarely described. We report a case of ARVD in a 60-year-old man who developed sick sinus syndrome during evolution (sinus node recovery time of 6113 mseg). Atrial arrhythmias may be explained by gradual replacement of right atrium myocytes by adipose tissue.
