Svt vs Vt

Regular broad complex tachycardias can be ventricular (VT) or supraventricular (SVT with aberrancy) in origin, and differentiation between the two will significantly influence management of your patients. Unfortunately, the electrocardiographic differentiation of VT from SVT with aberrancy is not always possible. Differential diagnosis of regular broad complex tachycardia Ventricular tachycardia (VT) Supraventricular tachycardia (SVT) with aberrant conduction due to bundle branch block SVT with any metabolic disturbance that slows supraventricular action potential propagation — hyperkalaemia, sodium channel blockade, severe acidosis Antidromic AVRT — re-entrant tachyarrhythmia seen in Wolff-Parkinson-White syndrome Accelerated idioventricular rhythm (AIVR) ECG features increasing the likelihood of VT Electrocardiographic features that increase the likelihood of VT include: ...

VT or not VT…that is the question Most of us know this question all to well. We are also probably familiar with the long list of ECG features “suggestive” of ventricular tachycardia (VT). Unfortunately, this list is not always intuitive, and can be difficult to recall and apply under pressure on the floor. How can we simplify things? I’ve spent the last few days coming up with a more easily applicable approach to this common dilemma. ...

Part four of a 5 part lecture series on ECG/EKG Interpretation on tachyarrhythmias with Dr Theo Sklavos and cardiologist A/Prof William Wang. This lecture series is aimed primarily at medical/nursing/paramedicine students and junior trainees, but will hopefully be useful as a refresher course for the more experienced.
