For Termination of paroxysmal supraventricular tachycardia:?

1. adenosine (Adenocard)
2. digoxin (Lanoxin, Lanoxicaps)
3.scopolamine
4. valsalva maneuver
5. esmolol (Brevibloc)
??

  #2

valsalva first :arrow: adenosine :arrow: digitalis :arrow: esmolol

  #3

1,2,4
esmolol-don't know

  #4

idiopathic is correct n even esmolol is right

  #5

esmolol is a fast-acting, short lived b-blocker indicated for IV use...it is the MC one used in this situation, but only after the others.

  #6

before giving digoxin ... the new medicine on the market after trying adenocard (adenosine) at 6mg, 12 mg, 12 mg is then to put the person on a cardizem (diltizem) drip ... usually give a 20mg bolus followed at a 10mg/hr dose. Have to watch the person for the underlieing rhythm ... ie does the person have a-fib/a-flutter under the SVT that is causing the fast ectopic rhythm.

another question ... what is the reflex that can be initiated other than the Valsalva manuever?

  #7

reflex brady due to increase in intraAbd pressure, increase in arterial pressure, carotid sinus and aortic knuckle sensors respond.

[left]Drug of Choice for Paroxysmal Supraventricular Tachycardia is Adenosine. It blocks conduction through the AV Node, and is also useful for preventing AV Node arrhythmias. It does so by affecting K+ and Ca2+ current. Most likely increasing K+ efflux leading to hyperpolarization.[/left] [left]Source - Lilly Cardio Pathophysiology[/left]
