It is also necessary to record ECG signals during the critical periods, for example, when the patient is having symptoms of a heart attack, or is feeling uneasy. Each recorded signal is considered to be an event. These events may be easily monitored and stored by a cardiac event recorder. A Cardiac Event Recorder is a device, which records ECG signals of a patient during the critical periods, for a specific time interval. The recorded events can then be observed or analyzed on a personal computer to determine the cause of uneasiness. The advantage of this system is that the patient can control the device and it maintains a history of his heart condition. This portable device accepts inputs from patients body through standard ECG electrodes and logs them on its onboard memory for 1-minute interval (30 seconds before and 30 seconds after the switch is pressed by the patient). A maximum of64/127 such events can be recorded. Each event can be displayed on a PC in Graphical format.                          Instead of using a magnetic tape, as was the practice so far, this device employs semiconductor memory. It is powered by rechargeable batteries and can monitor the events for a period of 24 hours.
