Bradycardia = too slow A of less than 60 beats per minute (BPM) in adults is called bradycardia. What\’s too slow for you may depend on your age and physical condition. Physically active adults (and athletes) often have a resting heart rate slower than 60 BPM but it doesn\’t cause problems and is normal for them. Your heart rate may fall below 60 BPM during deep sleep. Elderly people are more prone to problems with a slow heart rate. Causes of bradycardia Problems with the sinoatrial (SA) node, sometimes called the heart\’s natural pacemaker
Symptoms of bradycardia In extreme cases, cardiac arrest may occur.
Complications of bradycardia Severe, prolonged untreated bradycardia can cause: Treatment of the underlying medical cause Can usually be corrected with an Some medications can cause a slow heartbeat, in this case, medication may be adjusted. This content was last reviewed September 2016. Bradycardia is a slow or irregular heart rhythm, usually fewer than 60 beats per minute. At this rate, the heart is not able to pump enough oxygen-rich blood to your body during normal activity or exercise.
As a result, you may feel dizzy or have chronic lack of energy, shortness of breath, or even fainting spells. Bradycardia can occur for several reasons. Common causes of bradycardia include: Congenital heart disease (i. e. , condition you were born with) Sick sinus syndrome, also called sinus node dysfunction (the hearts natural pacemaker not functioning correctly) When your heart beats too slowly you may experience various symptoms. These symptoms including dizziness, fainting, chronic lack of energy, and shortness of breath, help your doctor access the severity of your heart condition and determine the appropriate treatment for you.
The treatment strategy for bradycardia is dependent on what is causing the slower than normal heart rate as well as the patients symptoms. If another medical problem, such as hypothyroidism, is causing a slow heart rate, treating it may indirectly affect bradycardia. Treating these problems with new medicines, or adjusting the doses of the medicines you are currently taking, may restore a normal heartbeat.
If the damage within the hearts electrical system is causing a slow heart rate, you may be eligible for an implantable heart device called a pacemaker. Pacemakers are small devices that are implanted under the skin, most often below your collarbone on the left or right side of your chest, to help restore the hearts rhythm. By sending tiny electrical signals to the heart to increase the heart rate, a pacemaker can relieve the symptoms of bradycardia.
