Supraventricular Tachycardia (SVT): ECG Interpretation Cheat Sheet
Supraventricular tachycardia, commonly abbreviated as SVT, refers to a group of fast heart rhythms that arise above the ventricles. These rhythms usually originate from the atria, the AV node, or an accessory pathway involving tissue outside the normal conduction system. On ECG, SVT most often appears as a regular narrow-complex tachycardia with a rapid ventricular…

VT vs. SVT with Aberration: ECG Interpretation Cheat Sheet
Wide-complex tachycardia is one of the most important ECG patterns to recognize quickly. The key clinical question is simple: is this ventricular tachycardia, or is it supraventricular tachycardia with aberrant conduction? In practice, the safest rule is this: a regular wide-complex tachycardia should be treated as VT until proven otherwise, especially in an older patient…
