<p>A neurostimulator (10) for stimulating the patient's vagus nerve (11) at or above the cardiac branch with an electrical pulse waveform at a stimulating rate sufficient to maintain the patient's heart beat at a rate well below the patient's normal resting heart rate, thereby allowing rest and recovery of the heart muscle, an increase in coronary blood flow, and/or growth of coronary capillaries. A metabolic need sensor detects the patient's current physical state and concomitantly supplies a control signal to the neurostimulator (10) to vary the stimulating rate. If rest is detected, the neurostimulator reduces the patient's heart rate below the patient's normal resting rate. If physical exertion is detected, the neurostimulator increases the patient's heart rate above the normal resting rate.</p> |
