Rate: ~150-160 bpm Regularity: Regular with one exception (3rd complex) P-waves: Potentially visible before the QRS in V5, likely retrograde in V1 and I PRi: either non-existent, associated WNL, or short-RP QRS: wide-wide ~180ms, V1-positive, IVCD appearance (I and V6 are inconsistent with RBBB)
Most likely rhythm: - Ventricular tachycardia with fusion beat
Others to consider: - Supraventricular tachycardia with pre-existing IVCD - Atrial flutter with pre-existing IVCD
Given patient's age, chief complaint, and findings on the ECG my field diagnosis would be one of VT. Likely I would give a trial of adenosine if stable, followed by procainamide if unchanged. If unstable, conscious sedation and elective synchronized cardioversion.
broad complex regular tachycardia. 1. VT with RBBB. LAH. 2. Other option - possible also SVT with aberrancy and RBBB. LAH.
always bit difficult to distinguish both. if IHD, wld be careful with adenosine. slow patient down first, otherwise, some synchronised electricity. Raf
