Holter and Event Monitors are devices that record a person’s heartbeat while they carry out their normal daily routine. They are used to detect abnormal heart rhythms, evaluate abnormal symptoms such as chest pain, dizziness, or fainting, and to monitor how current treatments are working and how they may be affecting the patient’s heart.
An Event Monitor only records your heartbeat when activated by the patient pressing a button, or when they have a qualifying event. For example, the monitors can be programmed to automatically record slow or fast heartbeats. This device is worn for a longer time period than a Holter Monitor, ranging from two weeks to over one month.
