What is an arrhythmia pulse?

An arrhythmia pulse is a heart rate that is too fast, too slow, or has an irregular rhythm. This can be caused by a variety of factors, including heart disease, thyroid problems, and certain medications. Arrhythmias can be serious, but they can also be treated. If you experience any symptoms of arrhythmia, such as chest pain, shortness of breath, or lightheadedness, it is important to see your doctor right away.
