Supraventricular tachycardia mnemonic

To remember about SVT, all you need to remember is the cause and you know the symptoms and treatment!

SVT occurs due to accessory conduction pathway through the AV node.

A - ABCD
Adenosine
Beta blockers
Calcium channel blockers
Digoxin

V - Vagal maneuvers
Valsalva
Ice immersion
Carotid massage

SVT: Start Vagal Treatment - - > If fails, use pharmacotherapy (ABCD drugs)

The P in Psvt reminds us that it presents with Palpitations in a hemodynamically stable patient (HR: 160-180/min)
*PSVT: Paroxysmal supraventricular tachycardia

Interesting fact: In an asthmatic patient with SVT, you can't give adenosine or beta blockers. The drug of choice in an asthmatic patient is therefore, diltiazem (A calcium channel blocker)

That's all!

  1. IN ALL SVT EXCEPT AVRT the TREATMENT is nodal block. IN AVRT DC SHOCK is treatment of choice. UNDER EMERGENCY WHEN IN DOUBT DC SHOCK (SYNCHRONISED) IS THE BEST TO TERMINATE ANY ARRHYTHMIA!
    In ABCD D stands also for DC SHOCK.

  3. yes...
    in the beginning is always the question? stable or not stable

    so

    Vagal --> A --> B (dont do if asthma) C D (only if heart failure patient) --> E (E for electrical cardioversion, which is of course synchronized)

    if unstable --> directly E
