A cardiac event monitor is a device used to record the heart's electrical activity (ECG) and keeps track of the heartbeat and rhythm. Cardiac event monitors are used when there is a need for long-term monitoring of symptoms that do not happen daily. Important heart health data can be tracked, recorded, and sent to patients’ doctors using a cardiac monitoring gadget, which reduces the need for frequent visits to the doctor's office, allowing the care team to monitor patients’ heart health from a distance.
