Procedures
Etheridge SP, Craig JE, Compton SJ. Amiodarone is safe and highly effective therapy for supraventricular tachycardia in infants. Am Heart J 2001; 141:105.
Therapy
This can help cure SVT. Your healthcare provider puts a thin, flexible tube (catheter) into a blood vessel in the groin. He or she then gently pushes it up into your heart. The area of your heart that causes your SVT is then either cauterized with heat or scarred with freezing energy.
Nutrition
Calcium channel or beta blockers can help correct heart rhythm. If you have SVT only 1 or 2 times a year, you may take beta-blockers or calcium channel medicines by mouth (orally) as needed. If your SVT is more frequent, you may need to take medicine every day. Some people may need to take several medicines to prevent episodes of SVT.

Clinics
- Supraventricular tachycardia (SVT) is the most common arrhythmia (abnormal heart rhythm) diagnosed in children. It is said to occur in up to 1 in 2500 children. While the problem is often congenital, meaning it is present at birth, the onset and severity of symptoms varies. Most of the time, the problem occurs in children with otherwi…
Diagnosis
- SVT is almost never life-threatening and treatment outcomes are excellent. It causes intermittent symptoms of heart racing and may cause chest pain, shortness of breath, lightheadedness, and/or fainting. The episodes may or may not be related to exercise. Although the set-up for SVT is often present at birth, the symptoms can start at any time. The episodes seem to occur more during infancy, then again at around 7 to 8 years of age, and then du…
Treatment
- Clinical features: As described above, infants may be diagnosed because of symptoms of congestive heart failure including poor feeding, unusual sleepiness, irritability, vomiting, rapid breathing, and/or pale skin color. In children, the problem is found because of symptoms of "heart racing" that may be associated with dizziness, lightheadedness, chest pain, shortness of breath, and/or fainting. Physical findings: Most of the time the physica…
Lifestyle and Home Remedies
- As stated above, the fast heart rate occurs intermittently and is rarely life-threatening. The episodes are started by extra, early heartbeats. Although these extra beats occur in all children and adults, they can be increased in frequency by caffeine and other stimulants such as decongestants found in cold and allergy medications or inhalers used to treat asthma. For this reason, people with SVT are often counseled to avoid caffeine in their die…
