Key Differences Between Telemetry Devices and Holter Monitors

Cardiac monitoring is a complex but vital undertaking, involving checking the heart for issues and subsequently relaying of the captured data to the patient’s cardiologist for further evaluation and action. There are two different approaches to monitoring the heart: telemetry and Holter monitors. Both Holter monitors and mobile cardiac telemetry (MCT) help cardiologists monitor a patient’s electrocardiogram for an extended period by determining the cause of a transient event by recording the patient’s heart rate and rhythm during normal activity.

Though similar, Holter monitors and telemetry devices have distinct differences, especially in these areas:

Monitoring Duration

While telemetry devices are capable of monitoring the human heart for up to 30 days, Holter monitors are generally designed to function without interruption for 24–48 hours. MCT is more reliable in the long run because of this key difference. It can accurately capture variations in the activities of the heart that occur throughout the monitoring period.

Operations

Both types of devices vary greatly in the manner in which they capture and transmit data although they must be worn around the chest. Holter monitors must be removed for a healthcare professional to retrieve the captured data. Moreover, they may only be worn for a maximum of two weeks and have a much shorter monitoring duration. Telemetry devices transmit data instantaneously, negating the need to remove them an making them generally more convenient for patients.
