![]() 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 medications can be very effective. Medications: Atrial Flutter can be treated with medication.This causes them to contract and pump blood to the 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 and reaches the Atrio-Ventricular (AV) node. It spreads throughout both the right and left atria causing them to contract evenly. All of this is appropriate.įrom the SA node, the electrical impulse is relayed along the heart’s conduction system. ![]() Certain medications may also slow the heart rate. When you rest or sleep your heart rate will slow down. If you are exercising, doing strenuous activity or are under a lot of stress, your heart may be faster. It provides the electrical spark that drives the heart to beat approximately 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 an electrical impulse to generate a heartbeat. Like any pump, the heart has an electrical system that controls how it functions. The lower chambers (the right and left ventricle) are the chambers responsible for pumping the blood out to the body via the arteries. The two upper chambers (the right and left atrium) and the chambers that receive blood as it returns from the body via the veins. The heart is a pump responsible for maintaining the blood supply to the body.
