6 Best Free ECG Viewer Software For Windows

Here is a list of Best Free ECG Viewer Software For Windows. Using these software, you can view patients’ ECG records. Most of these software support only one file format, but one software also supports multiple file formats. These ECG formats include aECG File (.xml), DICOM File (.dcm), ISHNE File (.ecg), MUSE-XML File (.xml), OmronECG File (.ecg), EKG files (.ekg), RAW files (.raw), etc.

You will also find some software which works as both ECG viewer and simulator. In these software, you can simulate the opened ECG graph. You can also vary the parameters of simulation, like scan time (in seconds), trigger level, etc.

My favorite ECG Viewer Software for Windows:

EDFBrowser is my favorite ECG Viewer software. It offers a lot of features by which you can customize the ECG signal of a patient. You can vary the amplitude and timescale of the ECG signal. EDFBrowser is not only an ECG viewer software but also a converter tool. It lets you convert various ECG formats into EDF/BDF.

EKG Viewer is another good software to view ECG files. It also lets you change the gain and timescale of a patient’s ECG. Besides this, it has a magnifying glass which helps you analyze the P, Q, R, S, and T waves of ECG.

You may also like some best free ECG Simulator, Hospital Management, and Dental Lab software for Windows.

EDFBrowser

• You can also change the timescale of an ECG as 12.5 mm/sec, 25 mm/sec, and 50 mm/sec.
• An ECG can be viewed as 12 Channel, 6 Channel+1, 3 Channel+1, and Beat Report.

The Measure tool lets you take the measurements on the ECG graph. You can take these measurements in any of the horizontal and vertical directions. The measurement summary shows width of the selected region on ECG graph (in msec), BPM, and height (in mm).

Glass is another useful tool available in the software. It acts as a magnifying glass and shows the magnified view of the region on which it is being hovered. After selecting this tool, press and hold the left click of your mouse to activate it on the graph. This tool is helpful in analyzing the P, Q, R, S, and T waves on the graph.

General features of this free ECG viewer software:

• You can change the background color.
• You can change the grid color and pattern.
• It lets you change the color, width, and style (ECG to be displayed as a solid line or dotted one) of the ECG pattern.
• You can also add comments to the patient’s ECG report.
• The ECG graph can be saved in JPG, PDF, DCM, and EKG formats.

NOTE: Even though the website has mentioned that the software is free for Bionet ECG Machine users, but I was able to download and use it.

EcgViewer

EcgViewer is another free ECG viewer software in this run-down. The default format to view an ECG file in this software is set to SCP-ECG, but you can change it in the settings menu. Other formats include MIT-BIH (Read Only), OMRON801 (Read Only), Philips XML (Read Only), and GE XML (Read Only). You can open multiple ECG files in this software and tile them horizontally or vertically.

An attachment icon is provided on the interface, clicking on which, you can add more information to the patient’s ECG file. This information includes referring physician’s name, name of the acquiring institute, systolic and diastolic blood pressure, diagnosis report summary, medical history of the patient, and free text column to add comments (if any).

You can also vary the amplitude scale and time scale of the ECG graph:

• Amplitude Scale: Four selections are provided which include 5 mm/mV, 10 mm/mV, 20 mm/mV, and 40 mm/mV.
• Time Scale: You can vary the time scale as 12.5 mm/sec, 25 mm/sec, 50 mm/sec, and 100 mm/sec.

Apart from the above-listed features, 6 different Leads formats are available including 6×2, 3×4, 12, 6, 3, and 1.

You can also save the record in SCP format at a different location on your PC.

C# ECG Toolkit

C# ECG Toolkit is another free software to view the recorded ECG files. It is a very useful software which supports multiple recorded ECG file formats. These ECG formats include aECG File (.xml), DICOM File (.dcm), ISHNE File (.ecg), MUSE-XML File (.xml), OmronECG File (.ecg), and SCP-ECG File (.scp).

After opening an ECG file, you will get the following options:

ECG Viewer

ECG Viewer is another free ECG viewer software for Windows. It is a DICOM viewer software, in which you can view the ECG files with .dcm extension. It is a straightforward software in which you can view and print the ECG patterns. In order to open an ECG graph of a patient, go to File > Open. The print option becomes available after opening an ECG file in the software.

In ECG Viewer, you can scan the ECG pattern by moving Red and Green lines over the pattern. As you start moving these lines on the ECG graph, it displays the respective amplitude (voltage) of the ECG signal in millivolt along with the time (in milliseconds).

FreeECG is a portable ECG viewer software for Windows. So, you can carry it in a portable device and use on the go.

FreeECG

FreeECG is another portable ECG viewer freeware for Windows. It is an ECG viewer and also an ECG simulator software, which simulates the opened ECG files. Only the ECG files with .ecg format are supported by this software.

For the traced ECG pattern, you can vary its refresh rate, trigger level, and scan time (in seconds). You can also enable or disable the sound of ECG pattern. However, this feature did not work while testing. Moreover, you can also record the ECG pattern to a custom .ecg file with an approximate file size (100KB/min).

You can play or pause the simulation anytime.
