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 someone’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.
