While the heart has its own Pacemaker that can regulate the heart rate, disorders can disrupt this function. Under these circumstances, a pacemaker can help set right the problem. Pacemakers are devices that maintain a suitable heart rate and rhythm by sending electrical impulses to the heart muscles.
Generally, pacemakers are implanted under the skin of the chest. This involves a minor surgical procedure. Pacemakers work with two parts; the leads and the pulse generator. While the battery and a tiny computer are placed in the pulse generator, the leads are threaded through the veins into the heart and implanted into the heart muscle. This helps regulate both the activity of the heart muscles and the heart’s electrical activities.
You cardiac doctor will program the minimum heart rate. If your heart rate drops below that set rate, your pacemaker generates (fires) an electrical impulse that passes to the heart muscle. Through this, heart muscles contract, creating a heartbeat. The kind of pacemaker used depends on the condition that you suffer from.
Pacemakers are widely used to treat problems like bradyarrhythmias. This is a condition where slow heart rhythms arise in the heart’s electrical conduction system (such as the SA node, AV node, or HIS-Purkinje system). Also, conditions like fainting spells (syncope), congestive heart failure, and hypertrophic cardiomyopathy (heart muscle disease) could be treated through pacemakers.
Your doctor can suggest the best type of pacemaker for you. It is recommended that if you undergo a thorough examination and then choose the right type. Take care of your heart, stay healthy!
