Adenosine is recommended for acute treatment in patients with regular SVT. (“pill-in-the-pocket”) acute doses of oral beta blockers, diltiazem, or verapamil

Administered by intravenous injection, a 6 mg dose of adenosine is successful in reverting SVT in 75% of patients, and a 12 mg dose is successful in more than 90% of patients.26 If adenosine therapy is unsuccessful, intravenous boluses of either verapamil or diltiazem usually terminate tachycardia,27, 28 but carry the risk of potentiating hypotension and bradycardia. This video demonstrates the treatment of a patient with supraventricular tachycardia (SVT) using adenosine. Supraventricular Tachycardia (SVT) can be a very rewarding condition to treat! It is generally easy to diagnose and can be very satisfying to treat.

21 22 Calan SR (verapamil): “I used Verapamil for 5 years to treat supraventricular tachycardia (SVT). With each visit to the doctor, they increased my dosage. I started out taking 30mg once a day, and ended with 180mg once a day. For the most part, my symptoms were never controlled. Verapamil: 2.5 to 5 mg IV over 2 minutes; repeat with 5 to 10 mg every 15 to 30 minutes to a maximum dose of 20 to 30 mg Esmolol (Brevibloc), metoprolol II; beta blocker Efficacy of verapamil was 90.5%. The mean dose of the drug used was 5.89 mg S.D + 1.92. Overall, efficacy of verapamil (90.5%) was statistically greater than adenosine (79.0%), p value of 0.021.

Occurs in ~ 15% of all pediatric cases. [Lewis, 2017; Paul, 1997] Current guidelines from American Heart Association: [de Caen, 2010] 1st dose of Adenosine – 0.1 mg/kg (or 6 mg for adult sized humans) 2nd dose of Adenosine – 0.2 mg/kg (or 12 mg for Furthermore, in our case, a higher dose of Verapamil had terminated a sustained SVT unresponsive to the first-line therapy of adenosine, electrical cardio version, and intravenous amiodarone. After Verapamil therapy, intermittent recurrent episodes of SVT were terminated rapidly by adenosine injection and oral amiodarone with a difference in the unresponsiveness for all of therapies before new to verapamil therapy, an initial daily dose of VERPAMIL SR 120mg daily may be appropriate.

For the most part, my symptoms were never controlled.

Verapamil. Diltiazem and the SVT persisted up to two doses of verapamil (2.5–5mg) intravenous over 2 Mar 2021 For immediate release formulations, initiate a dose of 240 to 480 mg daily in 3 to 4 divided doses; the maximum daily dose should be 480 mg/day. 7 Dec 2011 In most patients, the drug of choice for acute therapy is either adenosine or verapamil. The use of intravenous adenosine or the calcium channel supraventricular tachycardia (SVT) due to to AVNRT and AVRT are terminated by a 12 mg dose of comparing verapamil, digoxin and propanolol failed to.

Supraventricular tachycardia: ECG findings. 1.

At 240 mg, I experienced severe palpitations which woke me up at night, caused shortness of breath, and fullness in my neck. When I decreased the dose to 120 mg, the palpitations resolved. We evaluated the efficacy of single oral dose combining 20 mg pindolol and 120 mg verapamil in termination of paroxysmal supraventricular tachycardia (SVT) in 12 patients with recurrent symptomatic tachycardia. All had electrically inducible SVT lasting longer than 30 minutes.

Supraventricular Tachycardia (SVT) can be a very rewarding condition to treat! It is generally easy to diagnose and can be very satisfying to treat. When treating it, we also get to use one of the “coolest” medicines (ok, it isn’t quite as cool as Ketamine): Adenosine.Unfortunately, sometimes SVT can be recalcitrant (like a teenager) and won’t respond to the 1st dose of Adenosine.
