Arrhythmias are abnormal heart rhythms that occur when the electrical signals that cause the heart to beat are not working properly. There are two main types of arrhythmias: tachycardia and bradycardia.
Tachycardia is an abnormally rapid heartbeat, usually defined as a heart rate greater than 100 beats per minute. It can be caused by a variety of factors including stress, physical exertion, or an underlying medical condition. Symptoms may include palpitations, chest pain, shortness of breath, lightheadedness, or fatigue. Treatment may include lifestyle changes, medications, or a procedure to restore a normal heart rhythm.
Bradycardia is an abnormally slow heart rate, usually defined as a heart rate less than 60 beats per minute. It can be caused by a variety of factors including aging, damage to the heart, or an underlying medical condition. Symptoms may include lightheadedness, fatigue, or shortness of breath. Treatment may include lifestyle changes, medications, or a pacemaker to restore a normal heart rhythm.
Both arrhythmias are serious medical conditions that require prompt medical attention. It is important to speak to a doctor if you experience any of the symptoms associated with arrhythmias.
