Ambulatory ECG / Holter Monitor
This involves the application of three ECG electrodes and a monitor to capture every single electrical impulse whilst the device is worn.
A patient dairy is issued to document daily activities for greater understanding of heart rate response. Any 'event key' can be pressed by the patient to mark a symptom on the recorded ECG.
The monitor has greatest application in identifying arrhythmias as most patients will present with palpitations or syncope (black-outs).
Appropriate pacemaker use and atrial fibrillation rate control are other examples of ECG monitor application. Depending on the frequency of the patient's symptoms, monitors can be applied for 24, 48, 72 hrs or a week. There is no risk associated with the procedure. No preparation by the patient is required.
