ECG Logger Viewer - Rythmic HOLTER application by AdNovea (c)2017-2021

---

ECG Logger is a Wearable Cardiac Monitor for Long-Term Data Acquisition and Analysis.

The ECG Logger project is aimed for providing a very low-cost open-source "Hardware and Software" for a Rhythmic Holter. The hardware has been made very simple and is based on an Arduino Nano micro-controller with three companion boards for the SD card mass-storage, the instrumentation differential amplifier and the Real time clock. It can help monitoring arrhythmia syndromes such as bradycardia, tachycardia, extra-systoles or pause. In no case it can be use to replace a professional medical examination.

• HARDWARE/FIRMWARE ECG Logger: - Device (Holter) is for recording ECG signals
  https://sourceforge.net/projects/ecg-logger

• APPLICATION SOFTWARE ECG Logger Viewer: - Companion application software is for programming and viewing the Holder records

WARNING: DO NOT connected hardware to sources powered by mains (e.g. PC, DC pack, etc.)

IMPORTANT: device USB connection issues

1. FIRST plugged the ECG Logger device to your PC.
2. Wait for the device blue LED to flash.
3. Start the ECG Logger Viewer application software.
4. Press "Search Holter device" button (Zoom lens icon).

INSTALLATION

• Windows 10: see documentation to set permisions on configuration file if needed.

REMOVAL

• Backup your data (default folder is %USERPROFILE%\Mes documents\ECG Logger)
• From "Control Panel", under "Programs and Features" select from the list, the program you want to uninstall by a click on it. At the top of the list, click the "Uninstall" button.

MVSE applications may sometimes not create correctly the uninstall list entry. To overcome such an issues and remove the ECG Logger Viewer application, delete the corresponding files located under * %USERPROFILE%\AppData\Local\Apps\2.0 folder.

REINSTALLATION / UPGRADE

Re-installation or upgrade may fail due to previous installation if not re-done exactly from the same drive (e.g. E: drive). If so, you must have first to remove the previous installation (see Removal above).
