8/29/2023 0 Comments Heart arrhythmia![]() ![]() Risk factors for cardiac arrhythmias vary, depending on the particular type of rhythm disorder. Treatment usually involves implantation of a pacemaker, along with medication. Sick Sinus Rhythm (SSS) is not a disease but a group of signs or symptoms that show that the heart's natural electrical pacemaker, the sinus node, is not working properly. The heart’s electrical pathways may also be blocked by damaged heart muscle, such as after a myocardial infarction. If a life-threatening arrhythmia is seen the device treats it and stops it.īradycardia, or an abnormally slow heartbeat, may be caused by conditions such as sick sinus syndrome, in which the heart’s sinus node does not send electrical impulses through the heart properly. These devices are placed under the skin and continually monitor patients for life-threatening arrhythmias. Implantable defibrillators (ICDs) are often used for patients with ventricular tachycardia. Without prompt medical treatment, ventricular tachycardia may lead to ventricular fibrillation, a medical emergency that may lead to sudden death because the ventricles quiver chaotically and ineffectively instead of pumping blood. In ventricular tachycardia, abnormal electrical signals in the ventricles prevent them from filling and pumping blood efficiently. Catheter ablation is often very effective in curing SVTs. Medical treatment or cardioversion therapy may be required to return the heart to its normal rhythm. These are generally not life-threatening arrhythmias, but they can be quite irritating. In others, an extra electrical pathway between the atria and the ventricles allows signals to bypass their normal route through the heart, causing abnormally rapid heartbeats. Many involve a circular pathway in the atrioventricular (AV) node. Supraventricular (atrial) tachycardia (SVT) includes arrhythmias originating in the upper chambers of the heart. While atrial flutter may also lead to serious complications, curing the condition with ablation is possible in most individuals. In a small number of cases, atrial flutter results from ablation procedures for atrial fibrillation as the heart develops new electrical pathways to bypass the treated area. Treatments include anticoagulation and left atrial occlusion devices to prevent strokes, as well as antiarrhythmic drugs and ablation to prevent atrial fibrillation.Ītrial flutter is similar to AFib but the abnormal heartbeat is more regular and can persist for many days or even weeks. Atrial fibrillation may be temporary and even asymptomatic, but it can lead to serious complications such as stroke and heart failure. It is estimated to affect as many as one in every 10 people aged 65 and over. This change produces an irregular heartbeat, which is called an arrythmia.Ītrial fibrillation (AFib) is a rapid, irregular heartbeat caused by chaotic electrical impulses in the heart’s atrium. What is an arrythmia? The term "arrhythmia" refers to any change from the normal sequence of the heart’s electrical impulses. Our Heart Rhythm Management team is involved in numerous clinical trials of new treatments and devices, which means our patients have the first available access to novel technologies such as next-generation pacemakers, defibrillators, and ablation tools. We use advanced techniques such as pressure-sensitive catheters for heightened precision and cryoablation (freezing of excess heart cells). This allows patients to receive evaluation and treatments with minimal radiation exposure.Īt UT Southwestern, our specialists are experts in minimally invasive procedures that treat heart rhythm disorders, including catheter ablation. Our state-of-the-art ablation labs feature multiple three-dimensional electroanatomic mapping to provide detailed real-time visualization of arrhythmias during diagnostic and interventional procedures. Inpatient procedures, including ablations and device implantation, are performed at William P. We have a team of five attending physicians, four advanced practice providers, and more than eight nurses who see outpatients at our modern outpatient center on Inwood Road. ![]() Prepare for Your Procedure About Our ProgramĪt UT Southwestern Medical Center, our arrhythmia center is part of a comprehensive evaluation and treatment program. ![]()
