At present, the CRMD electrode lead is generally implanted with the help of an X-ray device to determine the location of the electrode lead. Bedside operation may also be performed under electrocardiographic detection in emergency situations, but requires real-time monitoring of pacing threshold, pacing impedance, and P/R wave amplitude values.

As shown in fig. 1, the present application provides a heart rhythm management device programmer with measurement capability.

The heart rhythm management device program controller comprises a mainboard 100, a power supply module 200, a display touch module 300, a program control module 400, an electrocardio module 500 and a measurement module 600.

The alternating current 900 is converted into direct current through the power module 200 to supply power to the main board 100 of the heart rhythm management device program controller.

The display touch module 300 is connected to the main board 100, and the main board 100 sends the content to be displayed to the display touch module 300 through a program for displaying operations such as reading and querying. The content comprises contents such as intracavitary electrocardiogram, pacing threshold value, P wave amplitude value, R wave amplitude value, pacing impedance and the like.

Microcontroller 610 is configured to send a regular pacing pulse low voltage signal to pacing measurement circuit 620. Meanwhile, the microcontroller 610 may further receive an amplified signal of an original P wave or an amplified signal of an original R wave sent by the sensing and measuring circuit 630, then the microcontroller calculates an amplitude value of the original P wave or an amplitude value of the original R wave, and calculates a program method of a related amplitude according to the waveform of the P wave or the R wave, and detailed steps thereof are not elaborated in detail in this application.

The microcontroller 610 receives the voltage signal sent by the sensing and measuring circuit 630 and calculates the value of the current drawn through the myocardium. The voltage signal is the voltage generated by the myocardial current passing through the sensing and measuring circuit 630, because the current in the sensing and measuring circuit 630 has a fixed impedance through the flow path impedance measuring circuit 634, the microcontroller 610 can calculate the value of the current passing through the myocardium according to the voltage signal and the fixed impedance value.

The microcontroller 610 adjusts the output pacing pulse low voltage signal to a known value according to the pacing pulse amplitude to be output, and the microcontroller 610 can obtain the value of the pacing impedance according to the obtained current value passing through the myocardium and the pacing pulse low voltage.

The power isolation circuit 670 is configured to obtain power from the motherboard 100, provide the power to the measurement module 600, and isolate the power interface of the motherboard 100 from the power interface of the measurement module 600, so as to avoid noise interference on the measurement module 600 caused by the power system of the motherboard 100, and improve accuracy of monitoring data.

The communication interface circuit 680 is configured to exchange data between the motherboard 100 and the measurement module 600, the motherboard 100 transmits a measurement command through the communication interface circuit 680, and the microcontroller 610 controls the pacing measurement circuit 620 or the sensing measurement circuit 630 to perform a corresponding measurement action after receiving the measurement command. After the measurement is finished, the microcontroller 610 sends the measurement result to the motherboard 100 through the communication interface circuit 680. Meanwhile, the communication interface circuit 680 may isolate the communication interface of the motherboard 100 from the communication interface of the measurement module 600, so as to avoid noise interference caused by the communication interface of the motherboard 100 to the measurement module 600, and improve accuracy of monitoring data.

The pace measuring circuit 620 is configured to receive the regular pace pulse low voltage signal sent by the microcontroller 610, and then amplify and process the pace pulse low voltage signal into a pace pulse signal which can stimulate the heart of the human body through the electrode pad. In this process, the amplitude intensity of the pacing pulse low voltage signal sent by the microcontroller 610 is continuously adjusted, so as to give pacing pulse stimulation with different intensities to the heart until the heart is stimulated to successfully pace, and the display touch module 300 will generate a pacing electrocardiogram, so as to determine that the amplitude of the pacing pulse low voltage signal is the pacing threshold value to be measured.

The sensing and measuring circuit 630 collects original P-wave signals or original R-wave signals in various electrocardiosignals of different types in a cavity, amplifies the original P-wave signals or the original R-wave signals and sends the amplified signals to the microcontroller 610, the microcontroller 610 calculates the amplitude value of the original P-wave or the amplitude value of the original R-wave, and calculates the program method of the amplitude of the original wave according to the waveform of the P-wave or the R-wave and the related amplification coefficient, and the detailed steps are not elaborated in detail in the application.

The sensing measurement circuit 630 also includes an impedance measurement circuit 634. The impedance measurement circuit has a fixed impedance configured to send a voltage signal generated by the current through the myocardium during pulse delivery at the impedance measurement circuit 634 having the fixed impedance to the microcontroller 610, the microcontroller 610 calculating a value of current through the myocardium and a value of pacing impedance, according to the above.

In at least another embodiment, pace measurement circuit 620 includes a burst protection circuit 621 and a pulse output amplification circuit 622.

The surge protection circuit 621 consists of a monostable multivibrator and nor gate. Microcontroller 610 outputs a periodic pacing pulse low voltage signal according to a set fundamental frequency, with a width that is the set pulse width. The rising edge of the pulse triggers the monostable multivibrator to generate a high level pulse. The high level pulse and the low level pulse generated by the microcontroller 610 are logically operated by a nor gate and then sent to control the charging and discharging circuit 624. Limiting the frequency of the output pulses to within a prescribed range of values when the circuit fails can prevent an unexpectedly high pacing rate from occurring.

The pulse output amplification circuit 622 includes an operational amplifier 623 and a charge and discharge circuit 624. The microcontroller 610 outputs pacing pulse low voltage signals with different amplitudes according to the set different pacing amplitudes, and the low voltage signals are sent to the operational amplifier 623 and output to the charging and discharging circuit 624 after being amplified to the pacing voltage.

The microcontroller 610 and the running protection circuit 621 act together with the charging and discharging circuit 633, and according to the frequency of the pacing pulse sent by the microcontroller, the capacitor bank device of the charging and discharging circuit 633 outputs the pacing voltage pulse, and the charging is to charge the capacitor bank device. When the frequency is abnormal, the rush protection circuit 621 will affect and limit the discharging frequency of the charging/discharging circuit 633, and the specific method is detailed as described above. In this embodiment, when the load impedance varies in the range of 200 to 1000 ohms, the pulse output amplifying circuit 622 can operate normally without affecting the amplitude of the pulse output.

As described above, the pacing threshold is determined and measured by varying the amplitude of the pacing pulse low voltage signal output by microcontroller 610, again by observing an electrocardiogram.

In at least another embodiment, the sensing measurement circuit 630 includes sensing and P/R wave amplitude measurement circuitry 631. The sensing and P/R wave amplitude measuring circuit comprises an electrocardio amplifying circuit 632 and an electrocardio filtering circuit 633, and is used for sensing, identifying and measuring the self-pulsation of the heart.

The electrocardiograph filtering circuit 632 is designed with a suitable band-pass filter according to different distributions of QRS complex, P wave, T wave and the like in the electrocardiograph spectrum in the cavity, so as to filter out P wave and R wave which need to be monitored. Because the cardiac electrical signal amplitude of the heart itself is very low, the P-wave and the R-wave must be amplified by the electrical amplifying circuit 632, the processed amplified signal is sent to an ADC (Analog-to-Digital Converter) of the microcontroller 610, and the microcontroller 610 controls the delivery of pacing pulses according to the set sensing sensitivity. When measuring the amplitude value of the P/R wave, the controller 610 calculates the amplitude value of the P/R wave by collecting the ADC value of the electrocardiographic signal and the related amplification factor, and the steps of the calculation procedure are not elaborated in detail in this application.

In at least one other embodiment, the microcontroller 610 primarily includes a DAC (Digital-to-analog converter), an ADC, a reference level, a timer, a GPIO (General-purpose input/output: port expander), a RAM, and a FLASH.

The DAC outputs pacing pulse low voltage signals of different amplitudes according to the set different pacing amplitudes, the maximum output voltage of which does not exceed the reference voltage or the supply voltage of the microcontroller 610, and the pacing pulses need to be adjusted to a maximum output amplitude much larger than this, so that the signals need to be amplified by the operational amplifier 623 in the pulse output amplifying circuit 622.

The electrocardiosignals of the electrocardiosignals are processed by the sensing and P/R wave amplitude measuring circuit 630 and then sent to an ADC of the microcontroller 610, the microcontroller 610 controls the sending of pacing pulses according to the set sensing sensitivity, and the ADC is also used for measuring the P/R wave amplitude and acquiring parameters of the pacing impedance value.

According to the pulse rules of the microcontroller 610, the ADC sends a regular pacing pulse low voltage signal to the pacing measurement circuit 620 to produce a final pacing pulse signal.

The sensing and measuring circuit 630 collects original P-wave signals or original R-wave signals in various electrocardiosignals of different types in a cavity, amplifies the original P-wave signals or the original R-wave signals and sends the amplified signals to the ADC, and the microcontroller 610 calculates an amplitude value of the original P-wave or an amplitude value of the original R-wave and calculates the amplitude of the original wave according to the waveform of the P-wave or the R-wave and a related amplification coefficient.

The ADC receives the voltage signal sent by the sensing and measuring circuit 630 and calculates and obtains the current value through the myocardium. The voltage signal is the voltage generated by the myocardial current passing through the sensing and measuring circuit 630, because the current in the sensing and measuring circuit 630 has a fixed impedance through the flow path impedance measuring circuit 634, the microcontroller 610 can calculate the value of the current passing through the myocardium according to the voltage signal and the fixed impedance value.

The reference level provides an accurate reference level for the DAC, the ADC and the electrocardio filter circuit in the perception measurement circuit, and the reference level is set to restrict the output of the voltage of each component.

The timer is used to control the frequency of the pulse output, the pulse width, the refractory period, and to determine the interference interval.

The GPIO is used to control the on and off of the burst protection circuit 621, control the output pulse of the pacing measurement circuit 620, and sense the on and off of the measurement circuit 630.

The RAM is used for storing program operation parameters and temporary variables.

If a patient with the CRMD needs to defibrillate with an external defibrillator, the defibrillation protection circuit 620 can protect the defibrillator from damage caused by defibrillation voltage not exceeding 5 kV.

In at least another embodiment, the measurement module 600 further comprises an EMI (Electromagnetic Interference) filter device interacting with the pacing measurement circuit 620 and the sensing measurement circuit 630, and the EMI filter device filters the high frequency Interference signal, the spike pulse signal, and the electrostatic pulse signal, so as to prevent Interference in the detection of the pacing threshold and the P/R amplitude during the monitoring process, and improve the accuracy of the detection. The power module 200 charges the battery 700 by converting the ac power 900 to dc power, and the battery 700 supplies power to the system when the cardiac rhythm management device programmer is unable to access the ac power 900 and the battery 700 has sufficient power. In some implementations, the battery is an energy storage battery. A battery is a rechargeable storage device for electrical energy, typically based on an electrochemical system, by which electrical energy is converted into chemical (stored) energy during charging and back into electrical energy during discharging.
