Supraventricular Tachycardia (SVT) Treatment Mnemonic: “ABCDE”


The mnemonic “ABCDE” amazingly outlines a strategic treatment approach for supraventricular tachycardia (SVT). Each letter represents a distinct pharmacological and clinical intervention—Adenosine, Beta-blockers, Calcium channel antagonists, Digoxin, and Excitation (vagal stimulation)—which collectively guide medical professionals in efficiently managing SVT episodes. This medical mnemonic serves as a valuable memory tool for healthcare professionals to streamline therapeutic decisions, restore normal heart rhythm, and alleviate symptoms associated with SVT, thereby enhancing patient care and outcomes.

SVT Treatment Mnemonic

Letter Treatment Mechanism
A Adenosine Slows conduction through the AV node, terminating reentry circuits.
B Beta-blocker Reduces heart rate and contractility through beta-adrenergic blockade.
C Calcium channel antagonist Blocks calcium influx, slowing AV node conduction and reducing heart rate.
D Digoxin Increases vagal tone and slows AV conduction, reducing heart rate.
E Excitation (vagal stimulation) Activates the vagus nerve, leading to decreased heart rate and AV conduction.
