    Abstract: The present invention relates to a method for creating hemodynamic sensor signal templates using an implantable medical device being connectable to a patient. A heart activity of a patient is sensed in order to identify a paced or sensed sequence of events of a heart cycle; hemodynamic sensor signals for consecutive heart cycles is sensed; and the sensed hemodynamic sensor signals for consecutive heart cycles is stored. Furthermore, sensed sensor signals are classified on basis of at least one predetermined heart event sequence condition and, for example, a template may be created using said classified sensor signals. The invention also relates to an implantable medical device for creating hemodynamic sensor signal templates, a computer program product, and a computer readable medium comprising instructions for bringing a computer to perform the method.
