1. A server, wherein the server is configured to:
receive information indicative of a photoplethysmographic signal detected by a first sensor of a wearable device, wherein the wearable device is associated with a user;
determine information related to a cardiovascular classifier based on the information indicative of the photoplethysmographic signal detected by the first sensor at the wearable device, wherein the cardiovascular classifier is configured to predict whether a cardiovascular event is occurring based on an electrocardiographic signal detected by a second sensor of the wearable device, wherein the cardiovascular classifier is derived from photoplethysmographic data but is adapted to predict an occurrence of the cardio vascular event based on electrocardiographic data; and
transmit the information related to the cardiovascular classifier to the wearable device so that the cardiovascular classifier is stored at and used by the wearable device to detect the occurrence of the cardiovascular event with the second sensor that is a different type of sensor than the first sensor from which the cardiovascular classifier was derived.
