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.
Cardiosense
Cardiosense is a Chicago-based health-tech company building an AI platform that turns raw physiological signals into clinical intelligence for heart failure. Its FDA-cleared CardioTag wearable simultaneously captures ECG, PPG and seismocardiogram (SCG) signals, and its machine-learning algorithms estimate pulmonary capillary wedge pressure (PCWP) - a key measure of cardiac filling pressure - noninvasively, so clinicians can spot a worsening heart before it lands a patient in the hospital.
