About the Developers of AfibAlert®

Lohman Technologies

Jack Lohman founded Cardiac Evaluation Center (CEC) in 1978 as a Holter scanning service, which grew as a pioneer in the industry through continuous dedication to improve cardiac monitoring technology. In 2004, Lohman Technologies was founded by the Lohman family in Sussex, Wisconsin as a vehicle for the Lohman family to carry on the tradition they established with CEC as innovators driven to improve the means in which patients with heart arrhythmias can be remotely monitored and diagnosed.


Lohman Technologies mission is to continually improve and provide mobile cardiac monitoring to bring peace of mind to heart arrhythmia patients and enhance the quality of care provided by physicians and healthcare organizations.

What patients and physicians are saying:

"It is the right kind of solution for patients, because it's a lifetime solution and Afib is a lifetime condition. I'm very impressed by the device."
Dr. Hugh Calkins, MD, Director, Cardiac Arrhythmia Service, Professor of Medicine
"I wish I had had it years ago, so I wouldn't have visited the ER so often…"
Frank (patient)
"The algorithm for detecting atrial fibrillation is extremely accurate. Another benefit to me has been the quality of the strips recorded compared to other single lead heart rhythm monitors. These high quality recordings are useful in identifying and monitoring other conditions as well as afib recurrence."
Robert Baker, MD, FACC, Nevada Cardiology Associates
"I have had the monitor for several years and have to tell you that this unit has saved my wife and I many days of anxiety and stress in knowing that I was not in Afib…"
Sherman (patient)
"The AfibAlert is beneficial in the clinical research arena to monitor for recurrence of atrial fibrillation after ablation. The quality of the ECGs it captures is excellent. In addition, patients find it extremely easy to use which yields high compliance"
John N. Catanzaro, MD, Assistant Professor of Medicine, University of Florida Health - Jacksonville
"I've had my AfibAlert for about nine months (Afib, for four years). It is easy to use and has taught me a lot about my particular Afib patterns. My meds were keeping my heart rate down most of the time and so I thought I wasn't fibrillating unless I had one of the big, obvious episodes; the monitor taught me that I was fibrillating quite often at low heart rates, too. I'm not sure I would ever have figured this out by myself. I only wish I had discovered AfibAlert a year or two earlier."
