In antidromic AVRT anterograde conduction occurs via the accessory pathway with retrograde conduction via the AV node.
Stable patients may respond to drug therapy including amiodarone, procainamide or ibutilide, but may require DC cardioversion.
In a haemodynamically unstable patient urgent synchronised DC cardioversion is required.
If in doubt treat as VT !

There is a regular, broad complex tachycardia at ~187 bpm; All QRS complexes are preceded by P waves with abnormal axis (Negative P in D1). These findings suggest atrial tachycardia. Note that one P wave is dropped in chest leads and made the rhythm irregular.
Other ECG findings:
Left anterior hemiblock
Ventricular conduction delay
