Interpret this ECG

A 27-year-old male is presented with nausea, fatigue, tiredness & one episode of vomiting. His past medical history of fibromyalgia and is on medication for the same. Her BP is low as 80/50 mmHg; heart rate was 60 beats/min; temperature was 35.1 °C, respiration was 18 breaths/min; and oxygen saturation was 99%. ECG is attached. What is your opinion?


This is a broad complex rhythm First question is to ask is - Is the rhythm regular? Answer is no Rhythm is not regular, there is wide variation in RR internal as seen in long lead There are very few rhythm are not regular - most common is atrial fibrillation which is irregularly irregular So certainly this ECG is of atrial fibrillation Now - are P waves seen? There are no P waves seen - this again confirms diagnosis of atrial fibrillation Now there is something happening to QRS complexes, they are wide Lead V1 shows a positive deflection - so it is right bundle branch block Because this is never possible in left bundle branch block. In left bundle branch block lead V1 has negative and wide deflection that is deep S wave Therefore, in this case, this patient is having right bundle Diagnosis Atrial fibrillation with right bundle branch block
