Heart treatment equipment for treating heart failure

A heart treatment equipment comprising:

• a right ventricle pulse generator for supplying a heart stimulation pulse to a first heart stimulating electrode provided in a right ventricle of the heart;
• a left ventricle pulse generator for supplying a heart stimulation pulse to a second heart stimulating electrode provided in a left ventricle of the heart;
• a nerve stimulator for supplying a nerve stimulating pulse for stimulating a vagus nerve to a nerve stimulating electrode;
• and
• a controller for selecting one of or both of said right ventricle pulse generator and said left ventricle pulse generator,
• wherein said controller selects both of said right ventricle pulse generator and said left ventricle pulse generator in response to a timing when said nerve stimulator generates a nerve stimulating pulse.

A heart treatment equipment comprising:

• a right ventricle pulse generator for supplying a heart stimulation pulse to a first heart stimulating electrode provided in a right ventricle of the heart;
• a left ventricle pulse generator for supplying a heart stimulation pulse to a second heart stimulating electrode provided in a left ventricle of the heart;
• an atrium event detector for detecting a contraction of an atrium;
• an atrioventricular delay time measuring portion for measuring a delay time for triggering the ventricle stimulation after a predetermined atrioventricular delay time in response to said atrium event detector;
• a heart rate monitor;
• and
• a controller for selecting one of or both of said right ventricle pulse generator and said left ventricle pulse generator in response to said heart rate monitor.

• and
• a controller for selecting one of or both of said right ventricle pulse generator and said left ventricle pulse generator,
• wherein said controller selects both of said right ventricle pulse generator and said left ventricle pulse generator when the interval of the triggers between the most recent ventricle stimulation and said ventricle stimulation is below a predetermined threshold value.
