9 Possible Fast Heart Rate In Adults Causes

The list below shows results from the use of our quiz by Buoy users who experienced fast heart rate in adults. This list does not constitute medical advice and may not accurately represent what you have.

Atrial flutter

Atrial flutter is an arrhythmia, meaning the system that regulates the heartbeat is not working correctly. The upper two chambers of the heart – the atria – beat faster than the lower two chambers and end up quivering, or fluttering, rather than beating.

It can be caused by high blood pressure; coronary artery disease; alcoholism; hyperthyroidism; and a previous case of rheumatic fever, which damages the heart valves.

Symptoms include fast, regular pulse; weakness or faintness; shortness of breath; and sometimes chest pain.

Since the quivering, fluttering atria cannot properly pump out the blood, the blood can stagnate and clot. A clot that travels through the body can cause a stroke. Also, the stagnated blood can cause blood pressure to drop and heart failure can result.

Diagnostic tests may include physical examination; EKG (also known as ECG); x-ray; MRI; and/or long-term monitoring with the patient wearing a Holter monitor.

Treatment first consists of medication to slow the heart rate and prevent blood clots. Defibrillation, catheter ablation, and surgery may also be done, as well as treatment of any underlying disorders.
