CARDIOLOGY - ECG LIBRARY
Case 31
30M Palpitations and SOB - Dx + supporting features
Expected Response
Rhythm irregularly irregular – atrial fibrillation
Ventricular rate variable – approx. 200-250/min – very fast
Left ward axis of broad complexes
2 types QRS complex – narrow and broad (mostly) – represent different pathways of activation of ventricles – narrow through AV node, broad through accessory pathway
Hence AF with rapid ventricular response in pt with accessory pathway (WPW)
Delta wave seen best in V4
