AfibAlert used to monitor patients in Johns Hopkins study

The Johns Hopkins Hospital Electrophysiology Division conducted a clinical study using MRI to Evaluate Radiofrequency, Cryothermal, and Laser Left Atrial Lesion Formation in Patients with Atrial Fibrillation.  Patients were monitored for recurrence of atrial fibrillation after catheter ablation. The researchers used the AfibAlert monitoring due to its high accuracy and ease of use for patients.

The aim of the study was to evaluate three different catheter ablation energy modalities (radiofrequency , cryothermal and Laser) with respect to lesion formation over time via MRI preprocedure 24 hours post procedure and at 3 months. This was then correlated to clinical outcome which was defined as recurrence of atrial fibrillation.

Dr. John N. Catanzaro, Assistant Professor of Medicine and Associate Program Director of the Clinical Cardiac Electrophysiology Fellowship at the University of Florida Health – Jacksonville described the overall experience with the AfibAlert. He stated, “Our main goal was to find a monitoring device that was accurate, easy to use and reliable for patients to monitor their atrial fibrillation symptoms on their own and be able to continue to enjoy activities of daily living without interruption.”

Outpatient monitoring for atrial fibrillation is vital given that the pathophysiology of the disease is one that evolves. The recurrence of atrial fibrillation can lead to a decreased quality of life and carries with it a risk of stroke. Patients can develop “silent” atrial fibrillation (without symptoms).

“Accurate and easy to use monitoring for recurrence of atrial fibrillation can aid in diagnosis.  This in turn can lead to earlier clinical intervention and improved quality of life for the patient.,” Dr. Catanzaro stated.
