ABSTRACT:
The invention relates to a method and a device for improved imaging by means of ECG triggering. A first trigger time A and a second trigger time B, as well as a threshold value for the heart rate variability is determined with the method according to the invention. The heart rate variability is subsequently calculated. Trigger time A is used as long as the threshold value is exceeded. Trigger time B is used when the threshold value is reached or exceeded.
