Wearable devices for cardiac arrhythmia detection: a new contender?

Area of Science:

• Cardiology
• Biomedical Engineering
• Digital Health

Background:

• Consumer smart devices and wearable technology are increasingly used for health monitoring.
• These devices enable non-invasive, ambulatory assessment of cardiac indices like heart rate and rhythm.
• Existing research highlights both the benefits and limitations of these technologies in detecting cardiac arrhythmias.

Purpose of the Study:

• To review the utility and deficiencies of consumer smart devices and wearables in cardiac monitoring.
• To address the implications of large-scale biometric data generation from these devices.
• To emphasize the need for improved clinician understanding in managing conditions like subclinical atrial fibrillation.

Main Methods:

• Literature review of studies on smart devices and wearables for cardiac assessment.
• Analysis of the potential impact of consumer-generated biometric data on healthcare.
• Discussion of clinical management strategies in light of technological advancements.

Main Results:

• Smart devices and wearables provide accessible, continuous cardiac data.
• Deficiencies exist in current devices for definitive arrhythmia diagnosis.
• Vast data generation may lead to over-investigation for conditions like subclinical atrial fibrillation.

Conclusions:

• Clinician education on smart device capabilities and limitations is crucial.
• Understanding this evolving field is vital for appropriate patient management and resource allocation.
• Further research is needed to optimize the use of wearable technology in cardiology.
