Supraventricular Tachycardia: Causes, Signs and Treatment

1. Introduction

Supraventricular tachycardia (SVT) is one of the most common types of arrhythmia, a form of irregular heart rhythm. It affects a person's heart rate, and is caused by a rapid or abnormally rapid heart rate, which is usually over 100 beats per minute. It's usually harmless and won't cause serious harm, but it can affect how well the heart pumps blood to other parts of the body.

2. Causes

The exact cause of supraventricular tachycardia is unknown, but it can be triggered by certain things, such as exercise, emotional stress, and stimulant drugs. In some cases, the triggers can be difficult to identify.

SVT can also be caused by other health conditions. Examples include hypothyroidism, sleep apnea, congestive heart failure, hypotension, and heart valve problems. Certain medical procedures and medications can also increase the risk of the condition, such as digitalis and isoproterenol.

3. Symptoms

There can be a range of symptoms associated with SVT, depending on the type and severity. Common symptoms include light-headedness, palpitations, a feeling of fluttering in the chest, difficulty breathing, and chest pain.

In extreme cases, supraventricular tachycardia can lead to shortness of breath,
