While availability of direct-to-consumer devices that enable the user to record heart rhythms continues to grow, use of the devices in clinical practice remains low. One reason for limited clinical use is that most devices allow the user to share an electrocardiogram (ECG) recording with their healthcare provider as an email attachment. It is impractical for busy clinicians to incorporate this raw data into normal workflows.

A small Cleveland Clinic study evaluated the use of the Kardia Mobile smartphone monitor coupled with the Kardia Pro (KP) platform for follow-up of patients following successful atrial fibrillation (AF) ablation. The KP platform utilizes artificial intelligence to triage preliminary interpretation of ECG tracings and route suspected abnormal recordings to the electrophysiologist’s in-basket. The study randomized 100 patients who presented three to four months after successful AF ablation into a self-monitoring group using the Kardia Mobile monitor, and a control group following normal standard of care. Healthcare utilization and anxiety were similar for the two groups, but more patients in the control group required additional ECGs or cardiac monitors compared to the self-monitoring group.

The study authors concluded that the KP platform can be effectively incorporated into the care of patients to assist in detection of AF recurrences. They noted:

The synergistic relationship between instantaneous interpretation via the automated algorithm, digital platform, patient, and healthcare provider is key for successful adoption of digital technology into busy clinical practices and will turn the technology into an asset rather than a burden and transform the relationship between the AF patient and the physician into a partnership rather than a unidirectional process.
