Heart ablation for a flutter11/4/2023 Because of the risk that atrial flutter may return with the above treatments, most patients with atrial flutter will require blood thinning medication to prevent blood clots forming. In addition, most patients will also require a medicine to try to prevent the flutter coming back. With this approach the possibility of the flutter returning remains present (approximately 50% of patients will have another episode of atrial flutter over the next year). You receive a short general anaesthetic and the shock reverts the rhythm to normal in almost all cases. When the heart is in flutter it can be reverted to the normal rhythm with a “shock on the chest”. If you elect to take medication, your doctor will discuss the different options and the possible side effects of these medications. In others however, the medications are ineffective and may produce side effects. In some people these medicines can be very effective. Atrial flutter can be treated with medication.What treatments are available for atrial flutter? One of the major reasons to cure atrial flutter is to prevent this risk of stroke. This can rarely cause blood clots and possibly stroke. This leads to slow blood flow in both of these upper chambers (the left and right atrium). The short circuit results in ineffective pumping of the upper chambers.In some people it can also cause dizzyness and chest pain. This produces palpitations, shortness of breath, and tiredness. The short circuit drives the pumping chambers very rapidly and sometimes erratically.This rapid short circuit has several consequences: A short-circuit develops in the right atrium as show in the diagram below.Ītrial Flutter is due to a short circuit in one of the upper chambers of your heart termed the right atrium. In some hearts, an abnormal heart rhythm develops when an electrical impulse either starts from a different location, other than the SA node, or follows a route (or pathway) that is not normally present. This causes them to contract and pump blood to the lungs and body. The impulse spreads through the AV node and down into the lower chambers or ventricles of the heart. It is therefore the only way in which an electrical impulse can reach the pumping chambers (the ventricles). This is a very important structure in the heart because it is the only electrical connection between the top chambers and the bottom chambers. When the impulse spreads over the right atrium it reaches the atrio-ventricular (AV) node. It spreads throughout both the right and left atria causing them to contract evenly. If you take certain medications, your heart rate may be slower.įrom the Sinus Node, the electrical impulse is relayed along the heart’s conduction system. When you rest or sleep your heart rate will slow down. If you are exercising, doing strenuous work or are under stress, your heart rate will be faster. The SA node gives off electrical impulses to generate a heartbeat in the range of 60 to 100 times per minute. The SA node is the natural pacemaker of the heart. Normally this electrical impulse begins in the upper right chamber of the heart (in the right atrium) in a place called the sino-atrial (SA) node. In order for the heart to do its work (pumping blood throughout the body), it needs a sort of spark plug or electrical impulse to generate a heartbeat.
