![]() 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. If you think you may have a medical emergency, call your physician or 911 immediately.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.

The reason for increased fremitus in a consolidated lung is the fact that the sound waves are transmitted with less decay in a solid or fluid medium (the consolidation) than in a gaseous medium (aerated lung). Tactile fremitus is pathologically increased over areas of consolidation and decreased or absent over areas of pleural effusion or pneumothorax (where there is liquid or air instead of usual lung). ![]() Pleural fremitus is a palpable vibration of the wall of the thorax caused by friction between the parietal and visceral pleura of the lungs.Tactile fremitus is normally more intense in the right second intercostal space, as well as in the interscapular region, as these areas are closest to the bronchial bifurcation. Go to your doctor to have him listen to your lungs with a stethascope. It is also possible that you have a lung infection and the gunk in you lungs (consolidation) actually rattles when you breathe. This is more likely to happen if you are tall. Hey there :o) Young, healthy men sometimes experience collapse in one or all lobes of the lung. ![]()
