From the Guidelines
Management for this patient should focus on addressing the supraventricular ectopy and associated symptoms, and I recommend starting with vagal maneuvers, such as the Valsalva maneuver, as the first-line intervention to terminate SVT episodes, as supported by the 2015 ACC/AHA/HRS guideline for the management of adult patients with supraventricular tachycardia 1.
Key Considerations
- The patient's underlying rhythm is sinus with an average rate of 86/Min, and rare supraventricular ectopy with short runs noted, which suggests that the patient may benefit from interventions aimed at reducing ectopy and preventing SVT episodes.
- The patient's symptoms, including burning, tingling, and sharp pain associated with sinus rhythm, may represent anxiety or heightened awareness of normal cardiac function, and could benefit from reassurance and possibly cognitive behavioral therapy.
Treatment Options
- Vagal maneuvers, such as the Valsalva maneuver, can be performed quickly and should be the first-line intervention to terminate SVT episodes, as recommended by the 2015 ACC/AHA/HRS guideline 1.
- If vagal maneuvers are unsuccessful, adenosine can be considered as both a therapeutic and diagnostic agent in narrow-complex tachyarrhythmias, as recommended by the 2015 ACC/AHA/HRS guideline 1.
- For hemodynamically stable patients, intravenous beta blockers, diltiazem, or verapamil may be reasonable for acute treatment, as recommended by the 2015 ACC/AHA/HRS guideline 1.
Monitoring and Follow-up
- The patient should be monitored for any changes in symptoms or ectopy, and follow-up appointments should be scheduled to assess the effectiveness of treatment and make any necessary adjustments.
- If medication therapy fails to control symptoms after 4-6 weeks of adequate dosing, referral to an electrophysiologist for consideration of catheter ablation would be appropriate.
From the Research
Management of Sinus Rhythm with Ectopy
The patient's underlying rhythm is sinus with an average rate of 86/Min, rare supraventricular ectopy, and short runs noted with the longest being 25 beats and a max rate of 143/Min. There are also rare ventricular ectopy and no significant pauses or high-grade AV blocks.
- The patient's symptoms include burning, tingling, sharp pain associated with sinus rhythm.
- Management of this condition may involve the use of antiarrhythmic drugs (AADs) to maintain sinus rhythm, reduce symptoms, and improve quality of life 2.
- AADs such as amiodarone, disopyramide, dofetilide, flecainide, propafenone, and sotalol have been shown to be effective in maintaining sinus rhythm, but they also have limitations, including proarrhythmic effects 2, 3.
- Beta-blockers, such as metoprolol, have also been shown to be effective in reducing the incidence of atrial fibrillation and improving symptoms 4, 5, 6.
- The choice of treatment should be individualized to the patient, taking into account the underlying rhythm, symptoms, and other factors, as well as the potential risks and benefits of each treatment option 2, 3.

- Beta-blockers, such as metoprolol, may be considered for reducing the incidence of atrial fibrillation and improving symptoms 4, 5, 6.
- Treatment should be guided by the patient's symptoms, underlying rhythm, and other factors, as well as the potential risks and benefits of each treatment option 2, 3.
