Arrhythmia What is it? Your heart has a natural rhythm when it is functioning properly. When you have an arrhythmia, or heart rhythm disorder, it means there is something wrong with your heart’s natural rhythm. There are many varieties of heart rhythm disorders. Your heart may go too fast or too slow, or there may be some other irregularity in the pattern of your heartbeats. Heart rhythm disorders are caused by abnormal electrical activity in the heart. What are the symptoms? There are different symptoms associated with the various kinds of heart rhythm disorders. You may experience some of these symptoms, or none of them. Not all arrhythmias are accompanied by symptoms. Palpitations Rapid heartbeat Feeling that your heart skips beats Fainting Dizziness Lightheadedness Shortness of breath Discomfort in your chest Fatigue or weakness How is it treated? Remote monitoring. Advanced technologies help us to monitor your heart’s activity while you go about your daily activities. Medication. For many patients, medications may be all that is required to control a heart rhythm disorder. Atrial fibrillation ablation. In an ablation, a thin catheter is threaded through a blood vessel in the thigh and up to the heart. Abnormal electrical activity in the heart is blocked, or “ablated” with high-frequency electrical energy. After ablation, many patients never experience arrhythmia symptoms again. Implantable cardiac defibrillators. Certain heart rhythm disorders put patients at risk of their hearts suddenly stopping. An implantable defibrillator can reset the heart’s rhythm should this happen. Ventricular tachycardia ablation. Patients who suffer from fast heartbeats that cannot be managed with medication can often be helped through VT ablation. Pacemakers. If you suffer from bradycardia, or a heartbeat that is too slow, a pacemaker may be used to help your heart maintain a normal heart rate. What is URMC’s approach? URMC is a world leader in heart rhythm disorders. Doctors here lead research that has changed the way heart rhythm disorders are treated around the world. We offer the most advanced and effective heart rhythm treatments to our patients. We perform more treatments for heart rhythm disorders than any other hospital in the area. In many cases, the treatments we provide are not available anywhere else in the region. URMC Cardiology has two fully equipped labs for ablation and device implants. These labs are staffed by nurses and technicians who work exclusively on heart rhythm disorders. Our newest lab will provide robotic navigation for radiofrequency ablation, giving our patients even greater precision, safety and versatility. Who should I contact?
