4 causes of irregular heartbeat that lead to rapid heartbeat.

A rapid heartbeat is a condition where the heart suddenly beats harder, faster, or irregularly. Those affected may feel this abnormal heartbeat in their chest. Several problems can lead to this condition.

A rapid heartbeat can appear for a short time and then disappear quickly, or it can last longer. This condition may seem frightening, but it is mostly not serious, according to the health website Medical News Today (UK).

Anxiety disorders can cause an abnormally fast heartbeat.

Factors such as excessive exercise, dehydration, insufficient sleep, or excessive caffeine and alcohol consumption can lead to a rapid heartbeat. These are all lifestyle-related factors.

Common health problems that can cause a sudden increase in heart rate include:

Heart rhythm disorders

Normally, the heart beats regularly due to the functioning of the conduction system within the heart. When this system malfunctions, it can cause arrhythmias. Many arrhythmias are harmless. However, some others require examination and treatment, such as atrial fibrillation, bradycardia, and supraventricular tachycardia.

Side effects of the medication

Some medications can cause side effects such as an abnormally fast heartbeat. These include certain types in the groups used to treat asthma, high blood pressure, as well as antihistamines, antibiotics, antidepressants, and antifungals.

People who frequently experience palpitations or a feeling of irregular heartbeat may be experiencing side effects from medication. Patients should discuss this with their doctor to discuss medication changes if necessary.

Anxiety disorders

Anxiety disorders are one of the common causes of a rapid heartbeat. This is because anxiety stimulates the sympathetic nervous system, leading to reactions such as rapid heartbeat, rapid breathing, nervousness, tension, chest pain, sweating, and other symptoms.

Some relaxation techniques and exercises such as deep breathing, stretching, or meditation can help reduce anxiety symptoms. If a rapid heartbeat is persistent, recurring, or severely impacts your life, you should seek medical attention promptly.

Hormonal changes

Hormonal fluctuations in the body due to menstruation, pregnancy, or menopause can cause a sudden increase in heart rate and palpitations. Additionally, this condition can also be caused by hyperthyroidism, which causes the thyroid gland to overproduce hormones, according to Medical News Today .
