However, the amount of caffeine a person can consume without adverse effects depends on their caffeine sensitivity. Learn how alcohol affects the body here. Nicotine is a highly addictive chemical found in cigarettes. According to the AHA, nicotine can cause increased blood pressure and heart rate.
Illegal stimulants, such as cocaine and amphetamines, can cause a person to have a higher heart rate. Research from found that people who use cocaine were more likely to experience irregular or increased heart rates. Doctors sometimes use amphetamines to treat people who have ADHD or narcolepsy.
However, amphetamines can cause a series of side effects, including :. Learn more about amphetamines here. These medications include:. Find out more about the causes of heart palpitations here.
Bitter orange: People might use bitter orange for heartburn, nasal congestion, weight loss, appetite suppression or stimulation, and athletic performance. Certain studies state that it can cause rapid heartbeat; however, the results were inconclusive.
Valerian: Valerian is a supplement used for anxiety, insomnia, depression, premenstrual syndrome, headache, and menstrual issues. Side effects of taking valerian can include heart disturbances, such as a rapid heartbeat, headache, upset stomach, uneasiness, excitability, mental dullness, and insomnia.
Ginseng: Ginseng is promoted as a general tonic to improve wellbeing. However, ginseng has side effects that can include increased heartbeat, insomnia, menstrual problems, breast pain, headache, digestive problems, and high or low blood pressure. Learn which supplements can lower blood pressure here. A person who experiences an increased heart rate due to caffeine, alcohol, nicotine, or illegal stimulants should try reducing the amount they consume. If a person is dependent on a particular drug, they should consider speaking to a healthcare worker or counselor to discuss treatment options.
If a person has a rapid heart rate after taking certain medications or supplements, they can speak to their doctor to see if there is an alternative medication they can take.

The same study also found that the average heart rate increased throughout pregnancy. Additionally, once a person goes through menopause , they have an increased risk of coronary heart disease.
The British Heart Foundation notes that a person in the postmenopausal phase of their life may feel that their heart is racing. In his prime, champion cyclist Miguel Indurain had a resting heart rate of just 28 beats per minute. Stress, medications, and medical conditions also influence your resting heart rate. Results of observational research studies support a link between health and heart rate.
Researchers from Norway previously reported the results of a large study looking at changes in resting heart rate over 10 years. They recruited more than 29, people without any history or heart disease, high blood pressure , or any other type of cardiovascular disorder, and measured their resting heart rates when they started the study and again 10 years later.
This study was published in the Journal of the American Medical Association. Among the group whose heart rates stayed under 70 throughout the study, there were 8. The most common type of arrhythmia , atrial fibrillation , affects about 2. Atrial fibrillation occurs when the heart's upper chambers the atria begin to beat rapidly and irregularly. The condition itself isn't life-threatening, but it increases the risk for stroke by allowing blood to pool and clot in the atria — increasing risk fivefold, says Hugh Calkins, MD , an electrophysiologist and director of the Cardiac Arrhythmia Service at Johns Hopkins Medicine in Baltimore.
Atrial fibrillation risk is lower before age 50 but then steadily increases with age. Blood thinners and medication to steady the heart rate and rhythm are mainstays of treatment.
In some cases, a special procedure called an ablation , which purposely scars the defective part of the heart to prevent it from passing on unwanted signals, may be recommended. Tachycardia occurs when your heart suddenly starts beating very fast. If it happens as a result of exercise, excitement, or fever, it's usually not a cause for concern and doesn't need treatment.
But one type of arrhythmia called paroxysmal supraventricular tachycardia PSVT is more dangerous. It creates extra heartbeats because electrical signals that move from the heart's upper chambers to its lower chambers tend to loop back around to the upper chambers. Tachycardia is most common in children and young people, and is more common in women than men. Ventricular fibrillation is the most deadly type of arrhythmia. It occurs when the lower chambers of the heart the ventricles begin to quiver instead of pumping normally.
Because these chambers handle most of the heavy lifting for the circulatory system, ventricular fibrillation causes blood flow to very nearly cease. Ventricular fibrillation usually happens in people with some sort of underlying heart condition. Those at risk can be treated with medication or an implanted defibrillator that will shock the heart if it stops beating.
Most irregular heart rhythms involve extra or skipped beats.
