Strong Clinical Evidence Highly Recommended
94
Score

The AliveCor KardiaMobile Card (Model AC-021) is a revolutionary step in personal cardiac monitoring, distilling the technology of a single-lead EKG into a credit-card-sized form factor. The device uses Bluetooth Low Energy to transmit data to the Kardia app, providing users with an 'Instant Analysis' of their heart rhythm. It is specifically designed to detect Atrial Fibrillation, Bradycardia, Tachycardia, and Normal Sinus Rhythm. A standout technical feature is its IPX8 rating, ensuring protection against water immersion for up to an hour. While the device features a non-replaceable battery, its ultra-slim design and clinical validation make it a top-tier choice for those needing reliable rhythm tracking on the go. The system provides professional-grade rhythm strips that can be easily shared with healthcare providers via email or PDF, though a data connection is required for cloud synchronization.
