From the Guidelines
Metoprolol is a recommended oral treatment option for supraventricular tachycardia (SVT) as stated in the 2015 ACC/AHA/HRS guideline for the management of adult patients with supraventricular tachycardia 1. The typical starting dose for adults is 25-50 mg twice daily, which can be titrated up to 100-200 mg daily based on response and tolerability.
- Key points to consider when using metoprolol for SVT include:
- Monitoring for potential side effects including bradycardia, hypotension, fatigue, and bronchospasm
- Cautious use in patients with asthma, COPD, heart failure, or diabetes
- Gradual tapering of the medication to avoid rebound tachycardia or other withdrawal symptoms
- According to the guideline, oral beta blockers, such as metoprolol, are useful for ongoing management in patients with symptomatic SVT who do not have ventricular pre-excitation during sinus rhythm 1.
- The guideline also notes that evidence for beta blockers is limited, but one small study found that propranolol, a beta blocker, was effective in reducing the number of episodes and duration of SVT 1.
- Additionally, the 2010 American Heart Association guidelines for cardiopulmonary resuscitation and emergency cardiovascular care recommend the use of beta blockers, such as metoprolol, for the treatment of supraventricular tachyarrhythmias 1.
- It is essential to weigh the benefits and risks of metoprolol treatment for SVT, considering the individual patient's medical history, comorbidities, and potential interactions with other medications.
- Overall, metoprolol is a viable treatment option for SVT, and its use should be guided by the latest clinical guidelines and evidence-based practice 1.

From the Research
SVT Treatment with Metoprolol Oral
- Metoprolol is a beta blocker that can be used to treat supraventricular tachycardia (SVT) 2, 3, 4
- It can be used acutely or as long-term therapy to control heart rate and prevent symptoms of SVT 2
- The use of metoprolol for SVT treatment is supported by studies that demonstrate its effectiveness in reducing symptoms and improving quality of life 3, 4
- However, the choice of treatment for SVT depends on various factors, including the frequency and severity of symptoms, patient preference, and underlying heart disease 3, 4
Alternative Treatment Options
- Vagal maneuvers, such as the modified Valsalva maneuver, can be used as a first-line treatment for SVT 5, 6
- Adenosine is also effective in terminating SVT episodes, especially when vagal maneuvers are unsuccessful 2, 3, 4
- Calcium channel blockers, such as diltiazem or verapamil, can be used as an alternative to beta blockers like metoprolol 2, 3
- Catheter ablation is a curative treatment option for patients with recurrent or severe SVT symptoms 2, 3
Special Considerations
- Patients with SVT should be referred to a heart rhythm specialist for further evaluation and management 3
- Treatment of SVT in special populations, such as pregnant women or patients with underlying heart disease, requires careful consideration of the potential risks and benefits of different treatment options 4
