A 46 years old male came with a history of palpitation for the last 6 months. ECG during tachycardia is shown below.
ECG (Click on the image to enlarge it)
ECG is showing narrow QRS complex, regular tachycardia @ 200 beats per minute, normal axis, no P wave seen, no ST-T wave changes seen.
Diagnosis of the ECG Narrow QRS regular tachycardia (Short RP tachycardia)
Differential diagnosis Atrioventricular nodal reentrant tachycardia(AVNRT) or Atrioventricular reentrant tachycardia (AVRT) or Atrial tachycardia (AT).
Patient was given carotid massage, following which his tachycardia subsided. Post tachycardia ECG is shown below.
ECG is showing sinus rhythm @115 beats per minute, normal axis, PR interval of 160 msec, there are no other ST- T wave changes.
Patient underwent Electrophysiological study which showed AVNRT with dual AV nodal physiology with a Slow-fast pathway. The patient underwent successful radiofrequency ablation and later was discharged in stable condition.
Let's discuss how to approach in a patient with narrow QRS complex tachycardia
Thank you
