ABSTRACT:
In a method and apparatus for stimulating and/or diagnosing the heart, a voltage is applied to the heart over at least a selected portion of the heart during an activation interval with a rise and fall, with the voltage having a first derivative with an absolute value that is less than the value of the derivative which, for a patient in question, would trigger the patient's heartbeat, and with a duration from beginning to end of each applied voltage signal of at least 30 ms.
