Disclosed are wearable devices, such as rings and bracelets, for monitoring and diagnosing cardiovascular conditions of a wearer, along with related systems, algorithms and methods. The disclosed wearable devices can continuously monitor the wearer's cardiovascular status by measuring heart rate, motion, blood oxygenation, and/or other properties of the wearer. Disclosed wearable devices can further comprise three EKG electrodes, including a first electrode on the inner surface adapted to detect a signal from the finger/wrist, a second electrode on the outer surface adapted to detect a cardiovascular signal from a finger of the opposing hand, and a third electrode on the outer surface of the frame adapted to detect a cardiovascular signal from a EKG lead location on the wearer's chest or leg. The wearable devices can be linked wirelessly to a mobile device that the person can interact with, and can further be linked to other distributed system components and healthcare providers.

Wearable cardiac electrophysiology measurement devices, software, systems and methods

A method of reconstruction of the standard 12-lead surface EKG given values of the electrical potential from an implanted medical device is described. This implanted device can be oriented in an arbitrary fashion and reconstruction technique is obtained through physical measurement of the orientation of the implanted device or correlation with a standard 12-lead EKG obtained from the patient.
