Why is Holter Monitor may be needed?
Holter monitoring is used to determine how the heart responds to normal activity and to determine if symptoms (palpitations, dizziness, fainting) correlate with any abnormalities. Abnormal results may include various arrhythmias (premature, atrial or ventricular contractions, paroxysmal supraventricular tachycardia,multifocal atrial tachycardia, bradycardia or pausesatrial fibrillation/flutter, and ventricular tachycardia.
How is the test done
A technician attaches several electrodes to your chest so your heart’s electrical activity can be monitored. That information is recorded by a small device that is worn on a belt or shoulder strap. At the end of the testing period—typically one to two days—you return the monitor so the data recorded can be analyzed. This test is painless.Some people may need to have their chest shaved so the electrodes can stick. You must keep the monitor close to your body. This may make sleeping difficult for some people. You should continue your normal activities while wearing the monitor.
Preparing For the Test
There is no special preparation for the test. Tell your doctor is you have an allergy to tapes or other adhesives.
Because this device cannot be immersed in water, showering or bathing prior to the test is suggested.
