In December 2025, a case report detailed how a 70-year-old man in New York City identified complete heart block after his smart mattress recorded a significant dip in his heart rate. The patient sought medical care after experiencing new shortness of breath, leading to his eventual diagnosis.
Why it matters
The case highlights the increasing clinical potential for consumer smart devices to act as early warning systems for life-threatening cardiac conditions. By identifying physiological shifts in the home, such technologies can prompt critical interventions before symptoms become severe.
A 70-year-old patient recorded an overnight heart rate of 42 beats per minute, significantly lower than his established baseline of 78 beats per minute. This discrepancy, tracked via ballistocardiography, prompted further diagnostic testing.
The players
Weill Cornell Medicine
This is a comprehensive academic medical center in New York City that integrates medical education, research, and clinical care.
NewYork-Presbyterian Hospital
This is a major nonprofit academic medical center and hospital system based in New York City.
The details
Sensors in the mattress detected body vibrations to estimate the patient's heart rate, which he confirmed using a smartwatch and blood pressure monitor. Following an electrocardiogram, doctors at Weill Cornell Medicine and NewYork-Presbyterian Hospital treated his complete heart block by implanting a dual-chamber leadless pacemaker.
Timeline
July 2023 saw the FDA approve the first dual-chamber leadless pacemaker system.
December 2025 marked the publication of the case report in the New England Journal of Medicine.
Health Landscape
This case demonstrates the practical clinical application of the dual-chamber leadless pacemaker system following its FDA approval in July 2023. It reflects a broader trend of integrating consumer-grade smart sensors with advanced, minimally invasive cardiac devices.
Patients using smart home monitoring devices should follow up with a physician if they detect consistent abnormalities or experience new symptoms like shortness of breath. This case confirms that data from smart mattresses can provide actionable evidence to assist doctors in diagnosing significant cardiac conditions.
The takeaway
Smart home devices can serve as critical indicators for cardiac health by catching anomalies that might otherwise go unnoticed. Residents should ensure that data from these tools are validated by medical professionals if physical symptoms arise.
