![]() 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. If your doctor thinks you may have one of these conditions, your doctor may give you an EKG, a chest X-ray, or an echocardiogram (echo test) to diagnose what’s wrong.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. problems with your heart’s valves or muscles.Sometimes a fast or irregular heartbeat can be a sign of a serious heart condition. Heart Diseases That Can Cause a Racing Heart If you notice that your heart is racing a lot and you’re not exercising or stressed (for example), then you should think strongly about seeing a doctor. Recording when your heart rate goes up can help your doctor better pinpoint what’s causing it. You can also try keeping a diary of your symptoms and write down what you were doing before you started to notice your heart was beating fast. If you notice that your heart is beating faster than normal, look for obvious explanations first: illegal drugs like ecstasy, methamphetamines, or cocaine.too much alcohol, caffeine, or nicotine.stress, fear, anxiety, or panic attacks. ![]() ![]() Many everyday situations that aren’t related to heart problems can cause your heart to race. Not all cases of a racing heartbeat are dangerous. Fast heartbeats can last for seconds to hours. ![]() When your heart beats more than 100 times each minute, that’s considered high (called tachycardia in the medical world). Normal hearts beat 60-100 times every minute. ![]()
