![]() ![]() Look carefully for P-QRS complexes and peaked T waves.Transient and suggestive of reperfusion, avoid antiarrhythmics.Ventricular rhythm with rate of 100-120 bpm, may mimic VT. ![]() Accelerated Idioventricular Rhythm (AIVR).Safest to consider WCTs of uncertain origin as VT unless good evidence suggests a supraventricular origin, as the ECG cannot reliably distinguish between them.If previous ECGs show known BBB in sinus rhythm identical with that during the tachycardia, suggests SVT with aberrancy.SVT with aberrant conduction (BBB, WPW).However, P waves may be difficult to detect or distinguish from artifact The sinus node continues to initiate atrial contraction independent of ventricular activity (AV dissociation) and may produce a capture beat or fusion beats.Wide QRS complexes (>120 ms), that should not be too wide ( 30s.Monomorphic Ventricular Tachycardia (VT).Differential Dx for Regular Wide Complex Tachycardia ![]()
