Optimized vector selection for a multi-axis accelerometer in an implantable medical device

A method for automatically selecting or proposing a vector of several vectors of a multi-axis accelerometer of an implantable medical device, wherein the accelerometer is configured to measure an acceleration of the implantable medical device along said vectors, and wherein the method comprises the steps of:

• collecting data when a patient's body is oriented in alignment with a pre-defined vector, wherein the data collected from each of the accelerometer's vectors is collected in a sequential fashion by cycling through each vector one after the other and the data is indicative of the magnitude of a static acceleration of the implantable medical device in the direction of the pre-defined vector, and
• automatically selecting or proposing a vector of said several vectors that is the one associated with the signal having the largest amplitude among the signals.
