In this course, we will teach you how to identify the clinical syndrome of paroxysmal SVT (pSVT). We explain the pathogenesis of the two common arrhythmias underlying this clinical syndrome; AVNRT and AVRT. You will learn how the underlying pathogenic mechanisms in these conditions result in identifiable diagnostic findings on the ECG. You will learn the definition and significance of the terms AV node dependent tachycardia and AV node independent tachycardia. We explain the mechanism underlying the efficacy of adenosine in the management of AV node dependent tachycardia. You will learn how to identify the ‘Wolf Parkinson White (WPW) pattern’ on the ECG and how this relates to the ‘WPW syndrome’. We discuss the nature of pre-excitation due to accessory pathways and the findings produced by this phenomenon on the ECG readout.
