Clinical Diagnosis

Pulmonary Embolism

Sinus tachycardia (most common finding)
S1Q3T3 pattern – McGinn-White Sign

Arrhythmogenic right ventricular dysplasia

– Presence of Epsilon wave after the QRS in lead V1-V3

– T wave inversion in right precordial leads V1-3 in the absence of RBBB

– Widened QRS in leads V1-V3 (> 110ms)

– Prolonged S wave upstroke of 55ms in V1-3

– NSVT or VT of LBBB morphology (RVOT VT)
