The correct answer is “C”
Antidromic AVRT

There is a regular, broad complex tachycardia at ~150 bpm; this rhythm is distinguished from VT by the presence of followings:

• Delta waves (best seen in leads D2, aVF, V3 and V4)
• Retrograde p waves with an RP interval>70ms (best seen in inferior leads D2, V4 and V5)
• electrical alternans
• ST elevation in aVR and ST depressions in most leads (not a specific finding)
