This test is performed on patients who have infrequent symptoms ( at least once every two weeks) that may be related to some sort of heart beat irregularity. The device is worn like a Holter monitor except it is worn for 2 weeks (OHIP rules not ours). The device is continually recording and deleting information about your heart rhythm. If an event occurs the patient must activate the device by pressing a button. The device will then record the heart rhythm for the 30 seconds before ativation and the 15 seconds after activation. This information is then stored. The device will stor 5-6 episodes and then will alert the patient tha it is full. The information is then downloaded to the Kingston Heart Clinic by telephone. You will be supplied with batteries and electrodes. The electrodes are changed daily. The batteries are changed when the device instructs you to do so.
