Bradycardia refers to an abnormally slow heart rate that is less than 60 beats per minute. A normal heart beat lasts between 60 and 100 beats per minute. Bradycardia refers to a form of cardiac arrhythmia, an abnormality in heart rate. This can be caused by a problem in the sinus node or it can be related to some sort of a disturbance in the passage of heartbeat signals through the A-V node.
Bradycardia can develop in some people who have certain illnesses that are not related to the heart.
In most cases, bradycardia that occurs in healthy and well-trained athletes does not need to be treated. In fact, in most people with bradycardia, treatment is not required unless the patients have symptoms that are due to a slow heartbeat. Following are some conditions causing bradycardia that need treatment.
Those people who are suffering from frequent, severe symptoms of sinus-node dysfunction tend to have only one treatment option left for them, which is a permanent pacemaker. A pacemaker is a device that is implanted and generates electrical impulses so as to regularize the heartbeat.
This is a medical condition that is treated with replacement doses of the thyroid hormones. Synthetic forms of hormones that are available include levothyroxine, liotrix, liothyronine and thyroid extract.
In those people suffering from an A-V node problem, the passage of the heartbeat signals can be blocked to multiple degrees. While some patients with less severe degrees of A-V block do not need any treatment, others may have to be monitored with regular EKGs, especially if they do not have any symptoms and have a heart rate that is adequate for the performance of everyday activities. Those people who have severe form on A-V block, which is also referred to as third-degree A-V block can be treated with the use of a special dual-chambered permanent pacemaker; this pacemaker has one electrode in the atrium and the other in the ventricle.
A patient with Lyme disease can restore the normal rhythm of the heart with the help of antibiotics that heal the infection fast, enabling bradycardia to resolve.
Take note to call your doctor if the pulse is less than 60 beats per minute. It is especially important for you to report your health to your doctor when you experience dizziness, lack of energy, weakness or fainting spells.
