L: orthodromic; R: antidromic
Why is adenosine contraindicated in antidromic WPW
adenosine can enhance anterograde conduction through the accessory pathway, leading to degeneration of the rhythm into ventricular tachycardia or ventricular fibrillation.
what does orthodromic mean
electrical impulse goes through the AV node into the ventricle and returns to atria via the accessory pathway.
