Your doctor also may ask you to undergo a stress electrocardiogram, also known as a treadmill test, to measure how well your heart can handle different types of exercise.Graham Adsit, MD, electrophysiologist, explains what an arrhythmia is and describes the symptoms of an irregular heartbeat. In general, if an activity makes you feel dizzy, lightheaded, or severely short of breath, you should stop the activity and seek medical attention.ĭepending on the type of arrhythmia you have and whether you have other heart conditions, a pacemaker or a defibrillator, you may have to avoid certain activities like contact sports. If you have an arrhythmia, speak with your doctor about what amount and what type of exercise is right and safe for you. Patients often develop a fear of exertion in order to prevent triggers sometimes, this can be taken to an extreme that results in a decline of the person’s psychological and physiological health. Can I exercise if I have an irregular heartbeat?Įxercise - even something as simple as walking - is an important part of staying healthy and preserving a sense of well-being. In rare cases, heart surgery may also be an option for some patients. That electrical current re-establishes, or resets, the heart’s normal rhythm.Ĭatheter ablation is a minimally invasive procedure that involves pinpointing, then destroying, the tissue causing the arrhythmia with extreme cold or heat energy. Cardioversion is frequently used to treat AFib it involves delivering electrical current to the heart through electrodes on the chest. Slow heartbeats are often treated with pacemakers, while fast heartbeats can be treated several ways.
How do we treat arrhythmias?ĭepending on the type of arrhythmia, we use medications, implantable devices like pacemakers, cardioversion or ablation to get the heart beating normally again. Often, this is fully reversible by correcting the electrical problem. Fast heart rhythms and heart rates can actually create heart failure. There’s also greater recognition now that an arrhythmia, if untreated and long-lasting, can itself lead to heart failure. An irregular heartbeat can be a symptom of an underlying problem like heart disease. If you lose consciousness, that's something that needs to be evaluated by a doctor.
A real warning sign for an arrhythmia, however, is fainting. If you feel an occasional skip in your heart -called a heart palpitation - often it’s something innocent and benign. So everything from feeling nothing to fatigue, shortness of breath, heart pounding and fainting is the spectrum of what we see with arrhythmias. Fatigue and poor exercise tolerance are common symptoms of many arrhythmias. Some patients can be desensitized to abnormal heart rhythms. If your heart rate is too fast, it can feel like your heart is racing or pounding in the chest. It depends on the arrhythmia: If your heart rate is too slow, you can feel tired, dizzy or even faint. There are many different causes, so that's why it’s important to get an accurate diagnosis by seeing a heart rhythm specialist. They can be worsened by lifestyle choices - things like smoking, excessive alcohol consumption, recreational drug use, obesity or stress. Arrhythmias are also associated with the natural aging of the heart and its electrical system.
What causes arrhythmias?Īrrhythmias can be caused by pre-existing conditions like coronary artery disease, diabetes, sleep apnea, heart failure or high blood pressure. AFib also can promote the development of, or exacerbate, congestive heart failure. AFib can make the heart prone to blood clots because its organized contractions have gone astray, increasing the risk for stroke. Atrial fibrillation (AFib), the most common abnormal heart rhythm disturbance across the globe, is characterized by fast, irregular heartbeats that start in the upper heart chambers. These type of arrhythmias include paroxysmal supraventricular tachycardia (PSVT), atrial flutter and ventricular tachycardia. Occasionally, the heart’s electrical signals get caught in a little short-circuit loop. Sometimes, it's just a single skipped beat, but arrhythmias can last minutes, hours, days and possibly years. Heart arrhythmias are caused by electrical problems. Remember that a heart arrhythmia is different from a heart attack. Heart arrhythmias occur when the heart beats too quickly, too slowly or irregularly. In particular, we specialize in catheter ablation, which offers the possibility to cure common heart conditions. At the University of Chicago Medicine Center for Arrhythmia Care, our team concentrates on advanced therapies for complex arrhythmias, namely atrial fibrillation and ventricular tachycardia.
