Supraventricular Tachycardia Symptoms

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
