A young female presenting with palpitation

0 2 443 8 months ago
A young female presents with palpitation and ECG shows a regular, narrow complex tachycardia at a rate of 190 bpm without preceding P waves. However, if you look very closely, there appears to be a negative (retrograde) P wave just after the terminus of the QRS in leads II, III and aVF and causing a “pseudo” S wave pattern. The most likely diagnosis, therefore, and is AV nodal reentrant tachycardia
