Detailed Description
In order to describe the technical contents, the achieved objects and effects of the present invention in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
Referring to fig. 1, a cardiac pacemaker postoperative follow-up data remote processing system includes a pacemaker 2, a pacing electrode lead 3, a fixed electrode, a forwarding device 4 and a cloud 5;
The fixed electrode is implanted into the body of the patient 1, the pacemaker comprises a battery and a circuit board, a first data transmission module and a controller are arranged on the circuit board, the battery is connected with the pacemaker through a circuit board, a pacing electrode lead, and the controller obtains the myocardial impedance measured in real time through the fixed electrode;
the forwarding device comprises a second data transmission module;
the cloud end is provided with a third data transmission module and a medical record library, wherein the first data transmission module is in data connection with the third data transmission module through the second data transmission module;
The cloud establishes myocardial impedance fluctuation rate Z detection algorithm:
Z=×Norm(HR(t));Norm(HR(t))=;
Wherein, For the myocardial impedance at time t acquired by the fixed electrode,Is a time window; Myocardial impedance measured for reverse time difference, i.e Myocardial impedance measured at time, norm (HR (t)) is heart rate normalization factor, HR (t) is heart rate at time t,A resting heart rate for the patient;
the cloud end calls patient medical records in the medical record library, and if the patient has emphysema, the cloud end establishes a respiratory correction myocardial impedance fluctuation rate Detection algorithm:=;
Wherein, A baseline value for patient respiration, obtained at a first follow-up visit after patient surgery; for real-time respiratory amplitude, chest wall impedance fluctuation calculation is synchronously acquired through a fixed electrode;
Cloud end judgment of myocardial impedance fluctuation rate Z orIf the data is active within the preset range, the data is not active, if the data is not active, a warning is sent out, and meanwhile warning information is sent out to the forwarding device through the third data transmission module.
From the above description, it can be seen that by establishing a myocardial impedance fluctuation rate detection algorithm through cloud, the myocardial impedance fluctuation rate is converted from the existing absolute time dimension to the heartbeat cycle dimension, and simultaneously, a heart rate normalization factor is introduced to peel off the interference of heart rate variation on the impedance, so as to avoid the influence of shortening the heartbeat cycle, and further, the influence of different heart rates is comparable, unnecessary clinical intervention is triggered due to the influence of motion, and simultaneously, a respiratory correction myocardial impedance fluctuation rate is further introduced, and the pulmonary impedance is reduced due to the reduction of the pulmonary impedance caused by the increase of the air content of pulmonary tissue of a emphysema patient, so that the thoracic impedance near the right ventricle of the fixed electrode is diluted, and the correction is required, and the respiratory amplitude is larger, so that the heart rate is improvedThe greater the effect of Z, the more true myocardial impedance changes are restored by inverse scaling.
Further, the cloud judges any two continuous myocardial impedance fluctuation ratesZ or any two consecutive respiration corrected myocardial impedance fluctuation ratesIf not, if yes, sending out a warning, and simultaneously sending out warning information to the forwarding device through the third data transmission module.
From the above description, it is known that by making a judgment of the slope, since the electrode is dislocated without falling down, it is a process that if the slope exceeds a preset value, it means that the fixed electrode may be displaced.
Further, the baseline value of the patient's breathUpdates are made at the time of patient visits to the hospital.
From the above description, it is known that the lung impedance decreases year by year due to the progress of emphysema, or emphysema changes with treatment, and thus periodic update is also required.
Further, the saidThe patient medical records in the medical record library are called through the cloud to obtain the medical records, if no record exists in the medical recordsWill thenSet to 60.

Further, if the patient HR (t) is greater than 100 times/min for more than 10 minutes, the maximum value of the preset range is automatically up-regulated by 20%.
From the above description, it can be seen that by automatically up-regulating the maximum value of the preset range, an alarm can be prevented from being triggered by an excessively conservative strategy during exercise.
Further, if the patient HR (t) is less than 100 times/min and lasts for 10 minutes or more, the maximum value of the preset range is restored to the original value.
Further, if the patient HR (t) is less than 50 times/min for more than 10 minutes, the maximum value of the preset range is down-regulated.
From the above description, it is seen that by patients having HR (t) less than 50 times/min, the patient is considered to be bedridden for a long period of time, avoiding bradycardia to mask impedance anomalies.
Further, the saidThe value is 300.
From the above description, it is apparent that byThe value is 300, namely 300 seconds and 5 minutes, and the detection is not excessively frequent in a period of usually 5 minutes, and whether the myocardial impedance fluctuation rate is detected for one period for a long enough time is problematic or not can be ensured, so that the detection error or the excessive sensitivity is easy to occur due to the fact that the detection is too short.
Further, the forwarding device is a mobile phone and/or an electronic watch.
From the above description, it is known that by using a mobile phone and/or an electronic watch, since the mobile phone and the electronic watch are very popular devices, a warning can be conveniently prompted to a patient through the mobile phone or the bracelet.
Further, the controller detects the battery power through the circuit board, and if the battery power is lower than a preset value, the controller sends out a warning of insufficient power to the second data transmission module through the first data transmission module.

If the patient HR (t) is less than 100 times/min and lasts for more than 10 minutes, the maximum value of the preset range is restored to the original value.
If the patient HR (t) is less than 50 times/min for more than 10 minutes, the maximum value of the preset range is down-regulated.
The saidThe value is 300.
The forwarding device is a mobile phone and/or an electronic watch.
The controller detects the battery electric quantity through the circuit board, and if the battery electric quantity is lower than a preset value, the controller sends out a warning of insufficient electric quantity to the second data transmission module through the first data transmission module.
