AV nodal ablation

We all know about the functioning of the heart. We learned in our school days, on different parts of our circulatory system, their role in the supply of blood and also on the arteries, veins and capillaries. But we are not aware of the electrical system which plays a vital role in the function of the heart to pump. In this topic, let us know on the functioning of the heart and also on the electrical system, coordinated with the functioning of the heart. The normal heart has four chambers, two above and two below. The two upper Chambers are called Atria and the two lower chambers are known as the ventricles. The Atria receive blood from the body and lungs. After collecting the blood, these other sends blood through the heart valves to the ventricles. The ventricles are filled with blood from upper Chambers contract, about a quarter of a second and pumps blood back to the lungs and body. The pumping function of the heart is coordinated by an electrical system. In a normal heart functioning, electrical impulses travel from the Atria to the ventricles. This electrical impulse is coordinated with the pumping function of the heart and pumping of blood to the lungs and body. The malfunction of this electric system results of irregular heartbeats, associated with symptoms of irregular blood pumping and other coordinated with the body's circulatory system. AV nodal ablation (ANA) is the treatment for patients with irregular heartbeats. In this treatment, changes the AV node-ventricular node lobbies, the electrical path that connects the rooms above the bottom Chambers of the heart to restore normal heart rhythm. AV nodal ablation procedureinvolves, AV node for freeze lock the electrical conduction through the heart region. During a typical AV node ablation, a Permanent pacemaker is attached to the chest. This pace maker works as an artificial electrical system, which adjusts the pulse rate in the lower chambers of the heart (the ventricles) to match natural wrist in the upper Chambers of the heart (the Atria). Signs and symptoms This is an accident that increases with age. Some people have no symptoms at all. The symptoms are usually associated with a rapid heartbeat. · Edema, especially in the feet and ankles. · May cause dizziness or fainting. · Weakness. · Lack of energy. · Shortness of breath and chest pain. Differential diagnosis · Wall movement. · Dilation. · Size of left and right atrium. · Radiograph of a patient's chest to control cardiac edges. · ECG-electrocardiogram. Treatment · In most cases, this risk can be treated with medications. A person with a rapid heartbeat will need medications to regulate heart rate and blood thinners to prevent strokes. · In some cases, this risk can be treated with a pacemaker mediated tachycardia (PMT).
