It is theoretically possible now, with clunky technology that is not wrist-worn. Development of a 12-Lead ECG Signal Processing Algorithm Using NI LabVIEW® and NI ELVIS: https://ieeexplore.ieee.org/document/8574627 https://ieeexplore.ieee.org/document/8574627 You would most likely need a 12 lead ECG/EKG too, to detect it accurately.
