Patent ID: 8774897

Claim:
A handheld system for detecting atrial fibrillation, comprising: a Valentine heart-shaped cordless body having multiple electrodes on both faces thereof, so that either face can be pressed against a human chest to make electrical contact; a processing unit, inside said cordless body, which is operatively connected to receive signals from said electrodes, and which is configured to determine from said signals whether atrial fibrillation is occurring; and at least two indicators on each face of said cordless body which are not displays; wherein said processing unit is configured to activate a first one of said indicators when said processing unit determines that atrial fibrillation is NOT occurring, and is configured to active a second one of said indicators when said processing unit determines that atrial fibrillation IS occurring, and wherein said Valentine heart shape of said body provides a culture-specific indication of an operationally-correct position and orientation for placement of said body, on a subject's chest and over the subject's heart with said Valentine heart shape facing upward, and whereby front/back orientation is made irrelevant to placing said body in said operationally-correct position.
