SVT

What is SVT?

SVT stands for supraventricular tachycardia, which is an abnormality of the heart's electrical activity that can cause your heart to beat too fast. You may experience symptoms such as chest pain, dizziness, lightheadedness, shortness of breath, and palpitations. SVT can be episodic, meaning it can come and go, or it can be persistent, meaning the symptom will not go away.

Types of SVT

There are two types of SVT: paroxysmal SVT and persistent SVT. Paroxysmal SVT usually occurs suddenly and can last up to a few hours. Persistent SVT can last days or weeks and can require medical intervention to control it.

Symptoms of SVT

• Chest pain
• Dizziness
• Lightheadeness
• Shortness of breath
• Palpitations

Treatments for SVT

Treatments for SVT are focused on restoring your heart rhythm back to normal. Medications such as beta-blockers and calcium channel blockers can be used to slow your heart rate and can be taken orally or intravenously. Other, more invasive treatments such as ablation may be recommended for persistent or recurrent SVT.

Prevention of SVT

In order to prevent episodes of SVT, you should avoid any triggers such as caffeine, illegal drugs, certain medications, stress, and vigorous exercise. If you have persistent SVT, you should make sure to follow your doctor’s instructions to make sure that it is well managed.
