Tachycardia is a condition that makes your heart beat more than 100 times per minute; it increased heart rate greater than 100 beats per minute.

Your heart rate is controlled by electrical signals sent to heart tissues. Tachycardia occurs when an irregularity in the heart produces fast electrical signals that quicken the heart rate, which is normally about 60 to 100 beats a minute at rest.

Cause- It is caused by something that disrupts the normal electrical impulses that control the rate of your heart’s pumping action.

  • Physiological – Exercise, Emotion, Excitement etc.
  • Pathological – Anxiety, Fever, Pregnant, Anaemia, Heart failure, etc.

Tachycardia is when the heart beats quicker than normal; symptoms include:

  • breathlessness (dyspnea)
  • dizziness
  • syncope (fainting, or nearly fainting)
  • fluttering in the chest
  • chest pain
  • lightheadedness
  • sudden weakness


The most efficient technique to avert tachycardia is to maintain a healthy heart and decrease your risk of developing heart disease. If you previously have heart disease, observe it and follow your treatment plan to lower your tachycardia risk. Take the following steps:

  • Exercise and eat a healthy diet.
  • Maintain a healthy weight.
  • Keep blood pressure and cholesterol levels under control.
  • Stop smoking.
  • Don’t use recreational drugs.
  • Limit caffeine.
  • Control stress.
