Claim 1
Independent Claim
210 words
Apparatus for determining whether a programmable pacing generator has been successfully programmed, said pacing generator including memory means for receiving and storing signals indicative of the parameters and/or modes of operation to control the application of its stimulating pulses to a patient's heart, means responsive to the storage of the encoded signals within the memory means to provide an indication thereof, and generator means responsive to the indication for generating test pulses in addition to the stimulating pulses, indicative of the successful programming of said pacing generator, said apparatus comprising: (a) keyboard means for receiving and entering by operator manipulation parameters and/or modes of operation in which to program said pacing generator; (b) transmitter means responsive to the mode of operation and/or parameters entered via said keyboard means for encoding and transmitting corresponding signals to said pacing generator; (c) means coupled to the patient's body for sensing the patient's heart activity signals including the stimulating pulses and test pulses; and (d) means responsive to the transmission of the encoded signals to said pacing generator for initiating the detection of the characteristics of the test pulse and for determining whether the detected characteristics meet given criteria and if so, for providing a manifestation that said pacing generator has been successfully programmed.
Claim 2
Dependent Claim
210 words
Apparatus for determining whether a programmable pacing generator has been successfully programmed, said pacing generator including memory means for receiving and storing signals indicative of the parameters and/or modes of operation to control the application of its stimulating pulses to a patient's heart, means responsive to the storage of the encoded signals within the memory means to provide an indication thereof, and generator means responsive to the indication for generating test pulses in addition to the stimulating pulses, indicative of the successful programming of said pacing generator, said apparatus comprising: (a) keyboard means for receiving and entering by operator manipulation parameters and/or modes of operation in which to program said pacing generator; (b) transmitter means responsive to the mode of operation and/or parameters entered via said keyboard means for encoding and transmitting corresponding signals to said pacing generator; (c) means coupled to the patient's body for sensing the patient's heart activity signals including the stimulating pulses and test pulses; and (d) means responsive to the transmission of the encoded signals to said pacing generator for initiating the detection of the characteristics of the test pulse and for determining whether the detected characteristics meet given criteria and if so, for providing a manifestation that said pacing generator has been successfully programmed.
Claim 3
Dependent Claim
34 words
Apparatus as claimed in claim 1, wherein there is further included display means, responsive to the manifestation of said detection means for displaying a message indicating that said pacing generator has been successfully programmed.
Claim 4
Dependent Claim
63 words
Apparatus as claimed in claim 1, wherein said detection means detects and measures the pulse width of the test pulses and the interval of time between the stimulating pulses and the test pulses, and for comparing the measured pulse width and interval of the detected test pulses with a given set of criteria to determine whether the pacing generator has been successfully programmed.
Claim 5
Dependent Claim
17 words
Apparatus as claimed in claim 3, wherein there is included memory means for storing the given criteria.
Claim 6
Dependent Claim
28 words
Apparatus as claimed in claim 4, wherein said memory means stores pulse width limits of 1.1 milliseconds and 350 microseconds, and interval limits of 50 and 150 microseconds.
