Tachycardia is caused by something that disrupts the normal electrical impulses that control the rate of your heart's pumping action. Many things can cause or contribute to problems with the heart's electrical system. These factors include:

Damage to heart tissues from heart disease
Abnormal electrical pathways in the heart present at birth (congenital)
Disease or congenital abnormality of the heart
Sudden stress, such as fright
High blood pressure
Drinking too much alcohol
Drinking too many caffeinated beverages
Medication side effects
Abuse of recreational drugs, such as cocaine
Imbalance of electrolytes, mineral-related substances necessary for conducting electrical impulses
Overactive thyroid (hyperthyroidism)

In some cases, the exact cause of tachycardia can't be determined.
