Where can I find the software and manual? All the software and manual are stored inside the SD card, which is located inside the battery compartment. Insert the SD card into the included USB adapter, insert the adapter in an USB port on your computer and copy the files in the SD card to your local drive. Install ECG Viewer from your local drive.
Save a copy of the software on your hard disk as the files in the SD card may be deleted accidentally.
How to read the data stored in DiCare-m1C? All the data files inside DiCare m1C are saved in the SD card. Insert the SD card into your computer's SD card reader before starting the software; otherwise the software would not be able to access the SD card. An alternative is to copy the data files to your local hard drive first. This is probably a better approach to manage your data.
Does the software work on Windows 7 and 8? We have installed the software in Win7 and Win8 machines and were able to access data stored in the local and network drives.
What is the purpose of the low-pass filter? The low-pass filter is to reduce the high frequency noise in the signal. If you are taking measurements using the electrodes on the device, one can reduce the ripples on the output by lowering the cut-off frequency for the low-pass filter.
You can try different cut-off frequencies to see which one gives you the best result. Select the highest cut-off frequency that gives good result as too low a frequency would distort the output.
What is the purpose of the high-pass filter? The high-pass filter reduces the low frequency noise in the signal. If the output drifts slowly up and down, increase the high-pass cut-off frequency may help.
You can try different cut-off frequencies to see which one gives you the best result. Select the lowest cut-off frequency that gives good result as too high a frequency may distort the output.
The high-pass and low-pass filters together form a band-pass filter. The idea is to keep the band wide enough to keep the useful information while eliminating the noise. Some experiments are required to get the best possible result.
When installing the software, several error / warning messages pop up. Ignore the messages to complete the installation. It appeared that the software expected to find a ECG data file in a specific folder and displayed the warning when the data file was unavailable.
I got an error message when opening a data file in an external drive. Plug in the drive prior to start up the software or copy the data file to a local hard drive and try again.
What is a "P-QRS-T category"? Each EKG cycle consists of 5 waves called P, Q, R, S, and T. Within a file, cycles with similar patterns are grouped together to form a category. If a file has 3 categories, one only need to examine 3 different patterns
What is the P-QRS-T analysis region? This region is for more detailed analysis of a P-QRS-T category. The P-QRS-T category selection bar on the left is for selecting the category for investigation.
In the diagram below, category 1 is being selected. 18/27 indicates that there are a total of 27 ECG waves in the file and 18 of them belong to category 1. The category selection bar shows that there are 8 categories in the entire file.
The waveform displayed is the stacking and magnifying of all the waveforms of the selected P-QRS-T category.
The graph on the lower right is the joint RR interval histogram. It is composed of every adjacent RR intervals plotted against each other. It reflects the variation of adjacent RR intervals. The more condensed or lined up the data points are, the more regular the heart rate is and the better the sinus node (SAN) is in control. A dispersed pattern would be a sign of trouble.
