1. A medical system, comprising at least
an implantable medical device, and
a multi-axis accelerometer comprised by the implantable medical device for measuring an acceleration of the implantable medical device along a plurality of vectors, wherein the multi-axis accelerometer is configured to provide for each vector a signal indicative of the acceleration of the implantable medical device in the direction of the respective vector,
wherein the medical system is configured to assess said signals to automatically select or propose a vector of said plurality of vectors that comprises the best alignment with a pre-defined vector,
wherein the medical system or the implantable medical device is configured to collect data from each of the multiple accelerometer vectors in a sequential fashion so as to cycle through each vector one after the other.
