Paroxysmal supraventricular tachycardia (PSVT) can cause a number of symptoms, depending on your overall health and how fast your heart is beating. People with heart damage or other coexisting medical problems experience a greater degree of discomfort and complications than those who are healthy. Some people have no symptoms at all.
Symptoms can come on suddenly and may go away by themselves. They can last a few minutes or as long as 1-2 days. The rapid beating of the heart during PSVT can make your heart a less effective pump so that your body organs do not receive enough blood to work normally.
The following symptoms are typical with a rapid pulse of 140-250 beats per minute:
Palpitations - The sensation of your heart pounding in your chest
Dizziness, or light-headedness (near-faint), or fainting
Shortness of breath
Anxiety
Chest pain or tightness
Circulatory System
Circulatory System, or cardiovascular system, in humans, the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. Among its vital functions, the circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature.
