Evaluation and Treatment of Sick Sinus Syndrome

WebMay 10, 2024 · The heart's rhythm is controlled by a tiny structure called the sinus node, which is located near the top of the heart's right atrium. The sinus node generates the electrical signal that initiates the heartbeat and controls the heart rate. The steady heartbeat originating from this node is called sinus rhythm. WebBigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat.Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat, or normal heartbeat.The two beats are figuratively similar to two twins (hence bi-+ gemini).For example, in ventricular bigeminy, a … durham nc bid opportunities

Bradycardia (Slow Heart Rate): Causes, Symptoms, Treatment

WebDescription. Sick sinus syndrome (also known as sinus node dysfunction) is a group of related heart conditions that can affect how the heart beats. "Sick sinus" refers to the sino-atrial (SA) node, which is an area of specialized cells in the heart that functions as a natural pacemaker. The SA node generates electrical impulses that start each ... WebSick sinus syndrome (SSS) is a relatively uncommon heart rhythm disorder. SSS is not a specific disease, but rather a group of signs or symptoms that indicate the sinus node, the heart's natural pacemaker, is not functioning properly. A person with SSS may have a heart rhythm that is too slow (bradycardia), too fast (tachycardia), or one that ... WebWhat Happens With a Normal Sinus Rhythm?
