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.
