Review Case Reports
Arrythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) and cathecholaminergic polymorphic ventricular tachycardia (CPVT): A phenotypic spectrum seen in same patient.
ARVD/C and CPVT are rare inheritable sudden cardiac death syndromes predominantly expressed in younger individuals. ARVD/C is characterized by a progressive fibrofatty replacement of the myocardium that predisposes to ventricular tachycardia while CPVT is characterized by exercise induced bidirectional/polymorphic ventricular tachycardia (VT) and a structurally normal heart. A mutation in different genes causes these syndromes but recently, mutation in a common gene RYR2 has been associated with both disorders and it has been suggested that CPVT and ARVD/C represent a phenotypic spectrum. We present a case unique in expressing both these phenotypes.

Case Reports
Smartphone ECG aids real time diagnosis of palpitations in the competitive college athlete.
Rapidly detecting dangerous arrhythmias in a symptomatic athlete continues to be an elusive goal. The use of handheld smartphone electrocardiogram (ECG) monitors could represent a helpful tool connecting the athletic trainer to the cardiologist. ⋯ AliveCor monitoring has the potential to enhance evaluation of symptomatic athletes by allowing trainers and team physicians to make diagnosis in real-time and facilitate faster return to play.
