![]() Sometimes, a heart doctor (cardiologist) uses the electrodes to stimulate the heart to beat at rates that may trigger - or stop - an arrhythmia. Once in place, the electrodes can map the spread of electrical impulses through the heart. In this test, also called an EP study, a doctor threads thin, flexible tubes (catheters) tipped with electrodes through the blood vessels to different areas within the heart. The doctor observes how your heart and the nervous system that controls it respond to the change in angle.Įlectrophysiological testing and mapping. The table is then tilted as if you were standing up. Your heart rate and blood pressure are monitored as you lie flat on a table. A doctor may recommend this test if you've had fainting spells. If you have difficulty exercising, a drug may be given to stimulate the heart in a way that's similar to exercise. During a stress test, the heart's activity is monitored while you ride on a stationary bicycle or walk on a treadmill. Some arrhythmias are triggered or worsened by exercise. If your doctor doesn't find an arrhythmia during those tests, he or she may try to trigger the arrhythmia with other tests, which may include: If symptoms are very infrequent, an event recorder may be implanted under the skin in the chest area to continually record the heart's electrical activity and detect irregular heart rhythms. In this noninvasive test, a hand-held device (transducer) placed on the chest uses sound waves to produce images of the heart's size, structure and motion. An event recorder may be worn for a longer period of time (up to 30 days or until you have an arrhythmia or typical symptoms). This wearable ECG device is used to detect sporadic arrhythmias. This portable ECG device can be worn for a day or more to record your heart's activity as you go about your routine. An ECG measures the timing and duration of each electrical phase in the heartbeat. ![]() During an ECG, sensors (electrodes) that can detect the electrical activity of the heart are attached to the chest and sometimes to the arms or legs. ![]() Sometimes, ectopic heartbeats may mean you are at increased risk for other serious abnormal heart rhythms, such as ventricular tachycardia.Tests to diagnose heart arrhythmias may include: The cause of the heartbeats, if discovered, may also need to be treated. The condition is only treated if your symptoms are severe or if the extra beats occur very often. Most ectopic heartbeats do not need to be treated. Exercise often helps people who are inactive. Limiting caffeine, alcohol, and tobacco may reduce the risk and frequency of ectopic heartbeats in certain people. Continuous ambulatory cardiac monitoring ( Holter monitor, patient-activated recording device, or implanted loop recorder).If the ectopic heartbeats do not occur very often, your doctor may not find them during a physical exam. Feeling like your heart stopped or skipped a beatĪ physical examination may show an occasional uneven pulse.Feeling your heart beat ( palpitations).Their causes should be investigated, although usually no treatment is needed. In adults, ectopic heartbeats are common. Most extra heartbeats in children are premature atrial contractions (PACs), which are almost always harmless. Ectopic heartbeats are rare in children without heart disease that was present at birth (congenital). Changes in the blood, such as a low potassium level ( hypokalemia)Įctopic beats may be caused or made worse by smoking, alcohol use, caffeine, medications such as stimulants, and some illicit drugs.Sometimes ectopic heartbeats are seen with: Premature ventricular contractions (PVC).The two most common types of ectopic heartbeats are: They often occur without a clear cause and are most often harmless. ![]() Ectopic heartbeats are small changes in an otherwise normal heartbeat that lead to extra or skipped heartbeats. ![]()
