What is SVT?
Supraventricular tachycardia (SVT) is a type of abnormally fast heartbeat that starts in the upper chambers of the heart. It is caused by an electrical problem in the heart that results in the heart beating too quickly. It usually causes a rapid heartbeat and can lead to palpitations, dizziness, chest pain, and shortness of breath. Although it is usually not serious, it can be uncomfortable and can lead to other health problems if not treated.
Types of SVT
There are two types of SVT: atrial fibrillation (AFib) and paroxysmal supraventricular tachycardia (PSVT). AFib is the most common type of SVT, and it is caused by an electrical impulse that causes the upper chambers of the heart to beat rapidly. PSVT is caused by a different type of electrical impulse that causes the heart to beat rapidly in a regular pattern. Both types of SVT can be treated with medications, lifestyle changes, or procedures.
Medications for SVT
Medications are the most common type of treatment for SVT. Beta-blockers, calcium channel blockers, and digoxin are the most commonly prescribed medications. These medications work by slowing down the electrical signals in the heart and preventing them from triggering an abnormal heartbeat. However, these medications may not be suitable for everyone and can have side effects such as fatigue, dizziness, and nausea.
Lifestyle Changes for SVT
Making lifestyle changes can also help to reduce the symptoms of SVT. Avoiding caffeine, alcohol, and nicotine can help to reduce the risk of triggering an abnormal heart rhythm. Regular exercise can also help to reduce the risk of developing SVT. Regular exercise helps to keep the heart healthy and can reduce the risk of developing arrhythmias.
Procedures for SVT
If medications or lifestyle changes are not effective in treating SVT, then a procedure may be needed. Procedures such as catheter ablation or pacemaker implantation can be used to treat SVT. Catheter ablation involves using a catheter to create a small burn on the heart to destroy or block the electrical signals that cause SVT. Pacemaker implantation is a procedure in which a pacemaker is implanted to help regulate the heart rate. Both of these procedures are usually successful in treating SVT.
Tips to Manage SVT
In addition to medications, lifestyle changes, and procedures, there are other ways to manage SVT. Learning to recognize the symptoms of SVT and how to respond to them can help to reduce the risk of an episode. It is also important to avoid triggers such as caffeine, alcohol, and nicotine. Finally, it is important to practice relaxation techniques such as deep breathing and yoga to help reduce stress and lower the risk of an episode.
When to See a Doctor
SVT can be a serious condition if it is left untreated. If you experience any symptoms of SVT, it is important to see a doctor as soon as possible. Your doctor can help you find the best treatment option for your condition. They can also monitor your condition and make sure that you are managing your SVT effectively.
