Cardiac pacemaker |
摘要 |
A cardiac pacemaker constructed for terminating tachyarrhythmias and including: an atrial electrode implantable in a patient's heart for supplying atrial stimulation pulses thereto and at which a pulse appears in response to each atrial contraction; a ventricular electrode implantable in the patient's heart for supplying ventricular stimulation pulses thereto, and at which a pulse appears in response to each ventricular contraction; separately switchable control paths connected to each electrode for causing one electrode to produce a stimulation pulse at a given time after the occurrence of a pulse on the other electrode; a first time delay unit connected to be actuated by signals derived from the heart behavior for supplying a stimulating pulse to the ventricular electrode at a time after the occurrence of a pulse on the atrial electrode, which is shorter than the physiological atrial-ventricular transfer time; and a second time delay unit connected to be actuated by signals derived from the heart behavior for supplying a stimulating pulse to the atrial electrode at a time after the occurrence of a pulse on the ventricular electrode which is shorter than a selected physiological period in the operation of the heart.
