Bradycardia

What is heart block ?

Heart block occurs when there is a partial or complete block of the heart’s electrical pathways between the atrium and the ventricles, resulting in a slow, unreliable heart rhythm. Symptoms are lightheadedness, Syncope, shortness of breath. Treatment: Implantation of a pacemaker is often recommended to prevent a slow heart rate that would cause symptoms.

What is Sick Sinus Syndrome?

Sick Sinus Syndrome is a failure of the heart’s natural pacemaker, the sinus node, which controls the rhythmic contractions of the heart. As a result, the heart beats slow and irregular. Sometimes the rate changes back and forth between a slow rate (bradycardia) and a fast rate (tachycardia). Symptoms are palpitations, lightheadedness and shortness of breath. Treatment: In most cases when the heart rate is too slow or too high, a pacemaker is recommended to control the heart rate.

How Is Bradycardia Treated?

bradycardia is most commonly treated with a pacemaker. A pacemaker alters the heart rate to help meet your body”s needs. The pacemaker provides signals much like the heart”s normal signals. Depending on your particular situation, a pacemaker may: Replace S-A node signals that are delayed or get lost on the pathway between the upper and lower heart Help maintain a normal timing sequence between the upper and lower heart Make sure the critical lower chambers of the heart always contract at an adequate rate

How is bradycardia diagnosed?

To diagnose bradycardia, your doctor will typically use an electrocardiogram (ECG) test. This is a painless test using electrode patches on your skin that shows how electrical signals travel through your heart and prints them out on paper. Your doctor can tell what kind of rhythm you have by looking at the printed pattern of your heartbeat.

What causes bradycardia?

bradycardia may be caused by a problem with your heart”s natural pacemaker (S-A node) or a problem with your heart”s electrical pathways.

What Is Bradycardia?

A normal heart typically beats 60 to 80 times a minute. At this rate, the heart pumps about 5 liters of blood throughout your body per minute. However, if the signal rate is too slow, the chambers of your heart do not contract often enough to supply the proper amount of blood and oxygen to your body. This condition is called bradycardia. bradycardia can affect the very young to the very old, though it is most commonly diagnosed among the elderly. More than 600,000 people worldwide receive treatment each year for bradycardia.
