• #1 Arrhythmia: Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/16749-arrhythmia

  An arrhythmia is a heart rhythm that isnt normal. Your heart may be beating too fast when youre at rest or just not beating in a regular pattern, for example. […] An arrhythmia disrupts the way heartbeat signals normally travel through your heart. […] A healthcare provider can tell you which type of arrhythmia you have and what kind of treatment you need, if any. […] A healthcare provider can find an irregular heartbeat during an examination by taking your pulse and listening to your heart. […] After assessing your symptoms and performing a physical examination, they may order diagnostic tests to help confirm that you have an arrhythmia. This can also help find the cause. […] You may also want to see an electrophysiologist a cardiologist who has additional specialized training in the diagnosis and treatment of heart rhythm disorders.

  Sometimes, especially if you do not have any noticeable symptoms of an arrhythmia, your doctor may find out you have one during a routine screening or physical for a competitive sport. […] To diagnose an arrhythmia, your doctor will ask you about any symptoms, lifestyle habits, and other risk factors of arrhythmias. Your doctor will also do a physical exam, which may include these steps: Checking for swelling in your legs or feet, which could be a sign of an enlarged heart or heart failure. Checking your pulse to find out how fast your heart is beating. Listening to the rate and rhythm of your heartbeat. Listening to your heart for a heart murmur. Looking for signs of other diseases, such as thyroid disease, that could be causing arrhythmias. […] If you or your child has a high risk of arrhythmias, your doctor may screen you regularly with heart tests. These tests, described in the next section, can help your doctor check whether your heartbeat is too fast, too slow, or irregular, even if you do not have any symptoms. Some of these tests may look at the hearts structure and function or may determine if you have risk factors for developing an arrhythmia.

  To diagnose a heart arrhythmia, a healthcare professional examines you and asks about your medical history and symptoms. […] You may have tests to check your heart and to look for health conditions that can cause an irregular heartbeat. […] Tests to diagnose a heart arrhythmia may include: […] If an irregular heartbeat is not found during those tests, a healthcare professional may suggest more tests to try to trigger the arrhythmia. […] Electrophysiological (EP) testing and mapping. This test, also called an EP study, can confirm a diagnosis of tachycardia or find out where in the heart the faulty signaling occurs. An EP study is mostly used to diagnose isolated arrhythmias. […] Treatment for a heart arrhythmia depends on whether the heart is beating too fast or too slow. […] Heart arrhythmia treatment is usually only needed if the irregular heartbeat causes significant symptoms or puts you at risk of more-serious heart problems.

  An electrocardiogram (EKG or ECG) is the most common test for diagnosing arrhythmias. An EKG records your hearts electrical activity. Your doctor may do an EKG during a stress test, which records your hearts activity when it is working hard and beating fast. […] Your doctor may also do other tests to diagnose arrhythmias. Blood tests measure the level of certain substances in the blood, such as potassium or other electrolytes and thyroid hormone. Monitors for long-term recording include Holter monitors and implantable loop recorders. These record your heart rhythm while you do your normal activities. Holter monitors measure your heart rhythm using a device that is outside of your body and are usually used for short periods of time. For an implantable loop recorder, your doctor will place the device under your skin. The recorder transmits data to your doctors office. Implantable loop recorders may be worn for longer periods of time and may help your doctor figure out why you are having palpitations or fainting spells, especially if these symptoms do not happen very often. An electrophysiology study (EPS), which is performed by an EPS cardiologist, measures the electrical activity of your heart. The doctor threads a wire through a blood vessel to your heart. The wire electrically stimulates your heart and triggers any underlying arrhythmia if you have one. If you have another condition that may raise your risk, an EPS can help your doctor find out your risk of developing arrhythmias. An EPS also allows your doctor to test whether a treatment, such as medicine, will stop the problem. Tilt table testing may help find the cause of fainting spells. You lie on a table that moves from a lying-down position to an upright position. The change in position may cause you to faint. Your doctor watches your symptoms, heart rate, EKG reading, and blood pressure throughout the test. Genetic testing can check whether you have a type of arrhythmia that is caused by specific genes. This test is important when one or more of your close relatives has an arrhythmia caused by the same gene or had cardiac arrest. Heart imaging tests, such as computed tomography (CT) scans or cardiac magnetic resonance imaging (MRI), may check the structure of your heart chambers, show how well your heart is working, look for evidence of scar tissue in your heart muscle, or sometimes may look at your heart arteries.

A resting heart rate that is too fast above 100 beats per minute in adults is called tachycardia, and a resting heart rate that is too slow below 60 beats per minute is called bradycardia. Some types of arrhythmias have no symptoms. Symptoms, when present, may include palpitations or feeling a pause between heartbeats. In more serious cases, there may be lightheadedness, passing out, shortness of breath, chest pain, or decreased level of consciousness. While most cases of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. Others may result in sudden death.

  Arrhythmia entails a broad spectrum of disorders of heart rate and rhythm abnormalities. Arrhythmia is broadly categorized into bradyarrhythmias and tachyarrhythmia based on the heart rate. […] Patients with an arrhythmia may exhibit a broad spectrum of clinical presentation from being entirely asymptomatic to sudden cardiac arrest. […] In patients suspected of arrhythmias, an electrocardiogram (EKG) is the first step and will usually give the diagnosis. […] The following modalities can be used for diagnosing based on the frequency of the symptoms a patient has secondary to a suspected arrhythmia.
