Evolution of Mobile Cardiac Monitoring Device - The Holter Monitor

Posted on June 9, 2022

A Holter monitor is an ambulatory electrocardiographic system discovered in 1957. This device works on Galvanometer’s principle to record electrocardiographic signals from an individual who is going about his daily activities.

Adopting this device, later formed as a backbone of rhythm detection and analysis in Cardiac Electrophysiology. Refer our infographics to know more about the evolution of mobile cardiac monitoring devices.



A Holter monitor is a type of ambulatory electrocardiography device, a portable device for cardiac monitoring for at least 24 to 72 hours. The Holter’s most common use is for monitoring ECG heart activity.

1947 – Post world war II, Dr. Norman J. Holter formed the Holter Research Foundation.

1947 – The first broadcast of a radio electrocardiogram

1947– Holter wore 80- 85 pounds of equipment on his back while riding a stationary bicycle.

1962 – Manufacturing partnership with Bruce Del Mar (Del Mar Avionics)

1965 – The Holter Research Foundation sold their patents Del Mar Avionics

1968 – Creation of a “mini-monitor”, described by Holter as “size of a cigarette package.”

1969 – Commercial production of the Holter mini-monitor began

1988 – Development of Micro Potential Analysis software for the scanning process of ambulatory ECG data.

1991 – The development of software for the analysis of spectral turbulence in the recorded ambulatory ECG.

2001 – The development of the smallest solid-state digital Holter recorder, with full fidelity and multiday capacity.

2002 – Work began on the newest generation “Impresario” data reduction, display, and report generation system.

2002 – Holter Monitoring instrumentation system, For the 40‐year period, 1962 through 2002, totaling over 10,000 units!

2002 – Holter Monitoring recorder deliveries had by then reached 40,000–50,000 units!

2009 – The first ECG patch monitor was cleared by the U.S. Food and Drug Administration (FDA)

2009 – Advances in HIPAA-compliant telecommunication and data analytics enable secure transmission of full-disclosure in near real-time, directly to the physician’s tablet or smartphone.

2010 and later – The next-generation remote cardiac monitoring devices that use deep-learning and software as a service (SaaS) remote cardiac monitoring platforms.

2019 – The hospitals segment in the global Holter monitoring systems market was valued at US$ 529.0 Mn

2027 – It is expected to reach US$ 775.8 Mn by 2027 at a CAGR of 4.9% during the forecast period.
