Abstract
A programmable cardiac tissue stimulator having a receiving coil and RF pulse width check/data separator (6) for receiving programming data, a communications State sequencer (8) for directing the sequence of command activities within the apparatus, command decode and address latch (12), memory (16, 18, 20, 22, 30, 40, 42) for storing the received programming data, pulse generator logic (24) for generating an output stimulation pulse according to a programmed stimulation scheme, a first timer (32), a second timer (34) and third timer (44) interactive with the pulse generator (24) and memory (16, 18, 20, 22, 30, 40, 42) for carrying out the timing functions of the pulse generator logic (24), a first sensor (46) for sensing electrical activity in the atrium, a second sensor (48) for sensing electrical activity in the ventricle, antitachycardia logic (50) for limiting the rate of natural stimulation of cardiac tissue, an output lead (54) to the atrium, an output lead (56) to the ventricle, and a control clock (28) for controlling timing within the apparatus.
