Changelog for BRAVEHEART v1.2.1

Contact us at braveheart.ecg@gmail.com with any questions or concerns.

New Additions:

  1. Rewrote code to calculate normal ranges for various VCG parameters to improve efficiency and readability. See user guide section 22 for further details.

  2. BRAVEHEART GUI now extracts information on race from XML/DICOM files for the purposes of calculating normal value ranges. If no information on race is available, BRAVEHEART assumes that the patient is white. The default race can be changed by editing line 3184 of braveheart_gui.m. BRAVEHEART Batch does not extract demographic information as this is only used for displaying normal ranges in the GUI.

  3. BRAVEHEART GUI now extracts information on age, sex, and race from DICOM files and HL7 XML files in addition to all other supported XML formats.

  4. GUI features for changing demographics have been changed. BRAVEHEART no longer assumes anything about missing values of age, race, sex, and BMI. If any of these values are missing, the appropriate normal ranges are calculated using margins. See user guide section 22 for further details.

  5. Added buttons to GUI section 6.6 to open the ECG file and to display select demographic data from XML files. See user guide section 12.7 for further information.

  6. If the load directory option is chosen when loading a directory, a counter is now displayed with the specific ECG number and the total number of ECGs that can be loaded using the next and previous ECG buttons. See user guide section 12.2 for further details.

  7. Added new variable VM_max_rpk_loc which returns the time (in ms) after QRS onset of the maximum R peak in lead VM. This corresponds to the time of maximal distance of the VCG loop from the origin. See user guide section 24.3 for further details.

  8. Added keyboard shortcuts for common actions within the BRAVEHEART GUI. See user guide section 26 for further details.

Bug Fixes:

  1. Fixed a bug that resulted in incorrect localization of the T wave maximum voltage value in there was very large ST segment deviation.

ECG Formats:

  1. Added ability to read Schiller XML format. See user guide section 23 for further details.

Changes to Mac Executable Installation:

  1. Installation of the Mac executable has been improved and significantly simplified. Installation no longer requires the .command script to copy .csv files to ~/home/BRAVHEART. The .csv files now reside in the directory where the executable is stored and they can be edited as needed from this location rather than ~/home/BRAVHEART. Installation instructions in user guide section 4 have been updated.
