ECG features suggesting VT:
• AV dissociation
• qR pattern in lead aVR with q wave >40ms
• Taller left rabbit ear

this arrhythmia is an example of idiopathic fascicular Ventricular tachycardia which is characterized by features of VT and the followings:
• QRS duration 100 – 140 ms. this is narrower than other forms of VT
• Short RS interval (onset of R to nadir of S wave) of 60-80 ms. the RS interval is usually > 100 ms in other types of VT
• RBBB Pattern
• Axis deviation depending on anatomical site of re-entry circuit
