Displaying RR-intervals

Hello! I am from Russia. Sorry for my English. I'm developing a device that records and analyzes heart rhythm man. At this stage of development, I created a VI that allows you to view the ECG in real time. And now I want to create in the VI window that displays the duration of RR-intervals. Need to be displayed on the vertical axis the duration of RR - interval, and the horizontal axis of the serial number of the RR-interval. I know that in the Biomedical Startup Kit has already created such a function. But I would like to create this window in my VI. If someone has this VI, please send it. Below is attached, written by me in my ECG VI.

You posted a text file not your VI. So we can not help you until you post your program. Be also aware of that we may help you. But you must show some efffort in the problem solving. Go to help in the toolbar. Then search for peak. Locate the "Peak Detection and Display.vi" That should give you a good start



Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

For the background I have an example of ECG Hate Rate Monitor. But now register themselves on the ECG Hate Rate display shows about 400 BPM. This can not be. I ask your assistance conditional. ADC sampling frequency - 530 Hz.

You have made your programming quite messy. To me it looks like you just have added functions found here and there but without thinking about what they do and how they work. Programming is attention to details. You have a flaw in how you store your data. But I managed to clean up your data.

I made something quick and dirty with your data. Take some time and look at your data. And ask your self. How can I change the settings to improve my analysis. It may just as simple as that. So let us start in that end.

I cleaned up my little VI, and now a window of RR-intervals displays the correct values. The problem was adding an item "Waveform build" to search for the peaks. Now I need to statistically process the results of RR-intervals. If possible, please send the original VI, which made statistical analysis of RR-intervals, for example, AR Spectrum Measures, Poincare plot, statistics (as is done in Biomedical Startup Kit)

Hi Kvanto,

Why not directly use Biomedical Startup Kit VIs?

Thanks!
