Why does the heart beat fast?

Increased heart rate is often the body's natural response to stressors such as anxiety, stress, exercise, and heart disease.

A rapid heart rate is when your heart beats more than 100 times per minute. There are a number of reasons why this may happen.

Do exercise

When exercising, the heart pumps blood faster to the muscles to maintain activity. Therefore, the heart beats faster but only temporarily. This is a good habit to help strengthen the heart muscle and the heart pump blood better. Everyone should exercise moderately so that the body can adapt and cardiovascular health gradually improves. Useful exercises include yoga, plank, walking, and jogging.

Caffeine

According to the US National Library of Medicine, after consumption, caffeine enters the bloodstream, stomach, and small intestine. It then begins to stimulate the central nervous system, specifically the receptors on the cells in the heart to increase the heart rate. This increases the rate of blood circulation and heart rate, which can increase by about three beats per minute. Increased heart rate can occur as early as 15 minutes after drinking coffee, and it takes about 6 hours for the body to eliminate caffeine.

This side effect rarely causes serious health problems. Caffeine does not cause chest pain in most people when consumed in safe amounts (no more than 400 mg of caffeine a day, equivalent to about 4 cups of coffee).

For people who are sensitive to caffeine, some other types of drinks such as soda, tea, and medications containing caffeine can aggravate rapid heart rate. Therefore, patients need to check the ingredients before using.

Medicine

Some prescription medications may contain stimulants such as caffeine or other ingredients that can sometimes cause heart palpitations. People who take psychiatric medications, beta blockers, or sympathomimetics and notice heart irregularities should talk to their doctor.

Obesity

Excess weight puts a lot of stress on the heart, which can sometimes cause heart palpitations. The heart of an overweight or obese person has to work harder to deliver blood and oxygen to vital organs.

Perturbation

The heart also beats faster when you are anxious, stressed or panicked. This condition increases adrenaline (a hormone based on sympathetic nerve activity) in the body. Anxiety, panic, stress can cause the heart to suddenly increase its rate or cause chest pain, which is sometimes mistaken for heart attack symptoms.

A rapid resting heart rate may be related to an underlying health condition such as an arrhythmia. Breathing exercises, relaxation, exercise, yoga, and a healthy diet may help. If the rapid heartbeat persists, the patient should see a doctor.
