• Measurement of the ECG with MyRIO

  1 can connect us monitoring ECG electrodes to MyRIO using the analog inputs?

  2 and then using the software amplification instead of the amplifiers?

  3. What is the best approach to collect values PQRST?

  software: Labview 2014 with all modules

  1. it depends on the output voltage of the sensor there.

  2. you can amplify the signal in the software, but if the signal is too small, you may have a problem with the resolution, you would like to use the whole range of ADC in myRIO to see something useful.

  3. I suggest an analogue input for this device and ensure that the signal is either already at the maximum range of the ADC or pre amplify before the digital conversion.

• filter the peaks on the signal from ECG pulse!, help!

  Hello

  I have RCV of the ECG signal. I filtered the ECG signal and get the resource (interval between each pulse of ECG) records.

  

  The source of the signal have noise I use a threshold but sometimes spikes of failure. Like the previous capture. Normally, if you get a pic of fault detected, I'll try to find this index to add to the left or right of the peak, normally I add to the lower value. This works if it has only a bad impulse between 2 good.

  The problem come when I have more than a ridge between the two coupons.

  Also, when the impulse of R a loss threshold I have trying to find the index and get 2 new reading making division 2 peak value.

  I have attached the method I've used to adapt it. I only works if I have 1 Ridge added on real measures of R or pulse 1 loss R, when I have several pics no work.

  I would like to hear an idea to make it work better. I don't like the idea of removing the value interval, I have 2 hours of reading and if I remove the values I have lower data outoput is why I tried to summarize or division of values to get the correct reading without losing any data.

  Perhaps, there is any better filter for ECG of entry, so I have a R-own pulse and less noise between ECG pulses.

  Any advice is welcome.

  Best regards, Fred.

  Almost.  in the last step, you have extracted the real part of the complex waveform.  Instead, you must retrieve the extent.

  

  BTW, this idea isn't mine.  I got from this article

• Drivers for a portable ECG

  Hello

  My diploma project calls: "the ECG signal processing. I figured I have a portable ECG. What I want to know is: are there drivers for such a device?

  Thank you in advance.

  "I have a portable ECG", that's what you say. So since you haven't, start by doing a search on google for such devices and find one that meets your requirements and price. I also mentioned the Group biomedical as a more suitable place for your questions.

• signal ecg retrieval

  Hi all

  In fact, I sent the signal of DMM, is a dynamic data from the client to the server, and what was good, the signal is received by the server, as it is sent by the customer but now I need to send the customer ecg.vi ecg signal to server ecg.vi which are listed below, but received quite and trying to solve this problem , but I've missed so if anyone can help with this and I thank very you much.

  Note: I just changed in ecg customer .vi, DMM signal by the ecg only simulation and anything in the server.

  Other things you need to do.

  1. use the same port number in both programs.  Right now they are different.

  2. remove the function of waiting on the server.

  3 Autoscale X axes on the cards in both programs.  The server is another Beach, and it turns out more is done zoom look like a different signal.

  Hi again,

  Maybe... but lets try other things first... Try these things...

  In some cases, it was discovered that updates/install (from got AppWorld apps) require additional steps in order to install the update. If the update will not install, please try this:

  1. Homescreen > Options > Advanced Options > Applications > highlight the app > BBKey > delete
  2. AppWorld > MyWorld > Login > highlight the app (if she shows at all, in any State) > BBKey > delete
  3. Use your PC (via the mass storage Mode) or your BB (via Media > BBKey > Explore) and find all references (folders, files) to the app delete everything you find. Search the memory of your device and your press card as well.
  4. Use this link to user guide AppWorld for re - install the app - then predict a new activation/registration key

  Also, please try a hard reset: turn on, remove the back cover and remove the battery. Wait a minute, then replace the battery and cover. Power on and wait patiently through the long reboot - about 5 minutes. See if things return to functioning. Like all computing devices, BB suffers from memory leaks and others... with a hard reboot is the best remedy.

  In addition, you can try this sequence:

  (1) AppWorld remove your BB (Homescreen > Options > Advanced Options > Applications)-if she prays that you restart the BB to do.

  (2) a Batt Pull restart as described above.

  (3) get a new link and install a new copy of AppWorld

  • Yet once, if he asks to restart, do.

  (4) restart another Batt-sweater

  One of these will get I hope it will.

• Can labview take own ECG data and send it to a remote computer with Labview to be viewed graphically? I guess that's for the TCP/ip works?

  IM building a circuit with a series of filters and an anoolgue to digital converter I just need labview to take this data and send it to a remote server any so we can access it from another computer and then represented graphically in a waveform graph.

  Any advice?

  Thanks in advance!

  As a previous poster has mentioned, shared variables would be a good way to do this.  This link on the use of shared variables should help.

• text output and the music given the live signal

  Hi there, I do not know really what to call what I'm doing, but I'll give you an overview of what I intended.

  I have a live ECG signal that I programmed to measure the heart rate (used a simulated below signal VI) and I want a pop-up message to display when the heart rate is more 100bpm. My problem is that it runs permanently if its more 100bpm, but I would like that it pop up once if 100bpm courses. I have the same problem with playback of music, I wish she could play > 100bpm and will stop when the heart rate is<>

  I am a very new labVIEW user and I have tried everything I can to sort this point, but I can't seem to find an answer. I would really like some help!

  Thank you

  Hi vcookie,

  When you need an example of VI for this function, you can create your own:

  -create a new VI

  -put the BooleanCrossingPtByPt on the BD

  -control of the wire at its entrance and an indicator of its release

  -take some time a loop around with a stop button and a delay of 100 ms

  -run the VI

  Now, whenever you change the Boolean value entered the indicator will show TRUE just for switching event: this function works just like the help of LabVIEW to explain it!

• How does the Daubechies Wavelet - 4 VI actually work?

  Hello

  I'm a student working on my final year project, one of the objectives is to detect the peaks of the ECG (R - pics) signals using the Daubechies Wavelet - 4 VI in LabVIEW. I am current using 2013 LabVIEW student edition (6 months trail), if that makes a difference.

  I'm quite confused on the wavelet of Daubechies-4 works:

  (1) levels how it decompose the signal in?

  (2) is there a way to adjust the level of decomposition?

  (3) are already applied in the VI filters or do I really need to design a filter myself?

  (4) what is the main difference between a Db4 PtByPt and a normal Db4 transformation in terms of LabVIEW?

  (5) Finally, how the VI actually superimposed on the signal Wavelet? Should the entire signal into account or should I take each pulse into consideration when the superposition of the wavelet?

  Thanks in advance for the answers.

  Kind regards

  Karine

  Hi Karine,.

  I was absent for the whole of last week, so I only read your answer today.

  The Wavelet Transform Daubechies4.vi you mentioned is indeed already included in LabVIEW (minimum full version, which is what offers Student Edition). From what I see, it's a very simple implementation of the transformation that the VI I mentioned in my post above. To better understand how it works, read first to the top of its help file (use ctrl + h), then open the VI by double-clicking on it to see the block diagram. From there, you will see that this VI essentially multiplication of matrix of coefficients db4 to the signal. That being said, we can go back to your questions:

  1. level of decomposition

  We see on the block diagram it's code to be a number such as recursively signal can be decomposed again by 2, for example signal length of 8 will have 2 iterations. You can change this setting by simply copying the pattern-block away and customize your VI, as long as you know what you are doing.

  2. the filters

  These are already applied in the VI as coefficients has explained in the help file and as seen in the block diagram.

  3 difference with his release Point by Point (PtByPt)

  They work in a similar way, but the calculation is done differently. The normal version uses the analysis based on the Bay and so buffering, then the analysis point by point is a new paradigm where input-output analysis is done continuously in real time. This is necessary for the deterministic real-time high-speed systems. If you open the VI, you can see that at the heart of it, it uses normal Wavelet VI for the análsis but bounded by a few functions to handle the case point by point. For more details, see the help of LabVIEW (ctrl +?) and read the analysis Point by Point.

  Finally, the Wavelet Transform Daubechies4.vi takes the entire signal into account, as can be seen in its block diagram.

  I hope this helps.

  Kind regards

• Example of signals with a filter anti-aliasing

  I use PCI-6259 6221 PCI and USB 6221 cards in different configurations. As I understand it, is that the anti-aliasing filter on all of these cards is fixed to pass to the frequencies of 1 MHz. If I'm a signal from a RG58U BNC cable that is supposed to contain higher frequency of 1 kHz sampling, but there is noise of high frequency present there. A sampling of the signal to 2 kHz would be enough to acquire the signal correctly, or these high frequencies would affect the components of low frequency on sampling?

  I read about too much sampling that allows you to use digital filters (I'm guessing that software filter can be used) If you sample the data at a higher rate. You should always use the anti-aliasing filter, but the required parameters are more relaxed. Would this work in my case? The anti-aliasing filter on my cards has a very high bandwidth, so I don't know how much I need to do to acquire the signal correctly oversampling. Is there an equation?

  Also, if the analog inputs for data acquisition cards are generated by a filter (for example when recording ECG or EEG) which allows you to specify a bandwidth frequency, I still need a filter anti-aliasing? Would be the distance between the amplifier and the DAQ card much a difference when it comes to the generation of noise on the cable?

  In general, I try just to see if my current collection method at the rate of Nyquish with the maps I have is good or not. I just save the data without even using any digital filtering (software).

  That's right - if you go down to 10kS/s then the temporal resolution and minimum pulse detection would 100us.  If it is a just sampling rate or not depends on your requirements for the accuracy of timing and jitter.  In other words, if it's OK that your pulse Detection could could delay until 100us then a 10kS/s sampling frequency should be OK.
