Supraventricular Tachycardia
Key Points
Key Points
- The writing committee generated a clinical practice guideline that provides for high-quality, evidence-based decision making for patients with SVT.
- The “2015 ACC/AHA/HRS Guideline for the Management of Adult Patients with Supraventricular Tachycardia” replaces the “2003 ACC/AHA/ESC Guidelines for the Management of Patients with Supraventricular Arrhythmias”. It utilizes new knowledge from clinical trials, treatments and drugs, and updates or replaces recommendations.
- Atrial fibrillation is not included in this guideline.
- Shared decision making is stressed in the document with attention to the patient’s preferences and treatment goals and their individual situations.
- The best available evidence indicates that the prevalence of SVT in the general population is 2.29 per 1,000 persons, and the incidence of PSVT is estimated to be 36 per 100,000 persons per year.
- Women have twice the risk of men of developing PSVT. Individuals >65 years of age have >5 times the risk of younger persons of developing PSVT.
- SVT has an impact on quality of life, which varies according to the frequency of episodes, the duration of SVT, and whether symptoms occur not only with exercise but also AT rest.
- While drug therapy is largely unchanged from 2003, there is one exception. Ivabradine is a new class of drug that has unique properties for reduction of the heart rate. The guideline provides new recommendations for use of ivabradine for ongoing management in patients with inappropriate sinus tachycardia.
- Ablation techniques have improved, including techniques to minimize radiation exposure. As such, catheter ablation may be reasonable in pregnant patients with highly symptomatic, recurrent, drug-refractory SVT with efforts toward minimizing radiation exposure.
- This guideline also provides new recommendations for the management of patients with asymptomatic WPW pattern, based on a systematic review of the evidence.
