Abstract
A method and system for pacing cardiac tissue is provided. An implantable medical device is implanted having an initial pacing function value based on a current cardiac rate of the cardiac tissue at implantation. A target pacing function value, a training increment and a training period are determined. The initial pacing function value is gradually increased to the target pacing function value by the training increment during the training period.

A method of pacing cardiac tissue using an implantable medical device, comprising:
- implanting the implantable medical device, the implantable medical device having an initial pacing function value based on a current cardiac rate of the cardiac tissue at implantation;
- determining a target pacing function value;
- determining a training increment;
- determining a training period;
- gradually increasing the initial pacing function value to the target pacing function value by to training increment during the training period;
- determining a duration of the training increment;
- increasing the initial pacing function value by the training increment to a first increased value;
- pacing the cardiac tissue at the first increased value for the duration of the training increment;
- and
- pacing the cardiac tissue at the target pacing function value when the first increased value is equal to the target pacing function value.
An implantable medical device, comprising:
- a processor;
- at least one pacing circuit operably connected to the processor wherein,
- a heart is paced at an initial pacing function value equal to a current cardiac rate of the heart when the device has been implanted in the heart and the initial pacing function value is gradually increased to a target pacing function value by a training increment over a training period;
- at least one pacing electrode for pacing the heart at a first increased value for a training increment duration when the initial pacing function value is increased to the first increased value by the training increment;
- and
- wherein the pacing electrode paces the cardiac tissue at the target pacing function value when the first increased value is equal to the target pacing function value.
A computer usable medium including a program for training a heart with an implantable medical device, comprising:
- computer program code that determines an initial pacing function value based on a current cardiac rate at implantation of the implantable medical device;
- computer program code that determines a target pacing function value;
- computer program code that determines a training increment;
- computer program code that determines a training period;
- and
- computer program code that gradually increases the initial pacing function value to the target pacing function value by the training increment during the training period.
