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. |
Happy learning, folks! 🙂
