Hi, thank you for your question. Fast heart beat is also known as tachycardia. Tachycardia occurs when something disrupts the normal electrical impulses that control your heart rate.
There are many causes and risk factors to a fast heart rate, such as congenital heart disease, anaemia, hyperthyroidism, low or high blood pressure, smoking, psychological stress or anxiety, exercise, drinking too much caffeinated drinks or alcohol, side effects of medications, use of recreational drugs and family history tachycardia.

Tachycardia can lead to other complications depending on its severity, such as heart failure, heart attack, stroke, fainting spells or sudden death. To prevent tachycardia, it is important to maintain a healthy lifestyle to lower your risk of developing heart disease. You should eat a healthy diet.
