The present invention relates to a device, system and method for detection of pulse and/or pulse-related information of a patient. To allow a single site solution, which is more robust to motion artefacts and arrhythmias, the device comprises an accelerometer signal input (51) configured to obtain an accelerometer signal acquired by an accelerometer sensor arranged at the patient's skin, a pulse signal input (52) configured to obtain a pulse-related signal of the patient, a patient information input (53) configured to obtain patient information, a model unit (54) configured to generate a model of accelerometer-based pulse palpation from the pulse-related signal using said patient information and context information indicating the context of the acquisition of the accelerometer signal, a feature extraction unit (56) configured to extract one or more features from the accelerometer signal using the generated model and/or from the pulse-related signal, and a detection unit (57) configured to detect the pulse and/or pulse-related information of the patient from the one or more extracted features.
