AliveCor
AliveCor is a Mountain View, California digital health company that pioneered the personal, FDA-cleared electrocardiogram (ECG). Its Kardia line of pocket-sized devices lets people record a medical-grade ECG on a smartphone in about 30 seconds, while AI algorithms screen for atrial fibrillation and other arrhythmias. Combining hardware, a subscription care service, and enterprise cardiology programs, AliveCor has recorded well over 160 million ECGs for millions of users and works with clinicians, employers, health systems, and pharmaceutical researchers.
Wearlinq
Wearlinq is a San Francisco healthtech company building eWave, described as the first continuous, wireless, FDA 510(k)-cleared 6-lead ECG cardiac monitor. About the size of a coin and worn on a skin-like adhesive patch, eWave pairs with a patient's own smartphone, runs 5+ days between charges in an AirPods-style case, and streams near-real-time data so clinicians get hospital-grade multi-lead visibility without the bulk of a wired Holter monitor. The company also operates an IDTF (independent diagnostic testing facility) staffed by certified cardiographic technicians who turn around STAT reports, closing the loop from device to diagnosis.
