What is supraventricular tachycardia?
If your heart rate suddenly or unexpectedly goes high without any episode of anxiety or when you are at rest, it might be a cause of concern. and should be consulted with the doctor immediately, as it can be an episode of supraventricular tachycardia (SVT).
The term contains Latin roots. Supraventricular means ‘above the ventricles’ which are the lower two sections of your heart. Tachycardia means ‘fast heart rate’. It is an umbrella term that covers arrhythmias, or abnormal heart rhythms, that occur from an electrical glitch or disrupt the upper chambers of the heart, including atrial flutter. This abnormal electrical signal intervenes with your heart’s natural pacemaker, also known as the sinoatrial node (SA node), causing a jump in the heart rate. A period of SVT may be unexpected and short-lived and some people who acquire this abnormally rapid heartbeat might not show any alarming signals.
For others, however, SVT can happen often and continue. People with SVT may also exhibit some alarming symptoms including palpitations, dizziness, chest pain, fatigue, shortness of breath, anxiety, sweating, and feeling faint.

SVT can happen to anyone regardless of age and gender and there’s no concrete cause for its onset. It can occur in your teens or early 20s. Sometimes you are born with abnormal electrical circuits in your heart. Damaged electrical circuits can also develop out of scar tissue neglected after surgery. Your heart rate is more likely to go faster if you drink too much alcohol and caffeine, smoke, are under a lot of stress or very tired, take certain antibiotics such as asthma drugs or herbal diet remedies, or consume illegal drugs, such as cocaine, ecstasy, etc.
Most of the people who get SVT particularly with rare episodes do not need any medication or procedures to control the condition. In some circumstances, you can just do certain lifestyle modifications that can assist you to get a heartbeat with a uniform and constant rhythm.
