8. How to use PMcardio

  • Updated

Using PMcardio does not require any special training other than the initial tutorial as well as the instructions for use (this document).

 

8.1. ECG digitization

8.1.1. Supported ECG formats and layouts

PMcardio supports the analysis of the ECG formats below. You can change your preference at any time by clicking the “Change Format” button in the top right corner of the screen (see section 8.4. step 2 - 4). Make sure that the selected format matches the lead layout of the ECG in front of you.

8.1.2. Digitization requirements

The following image formats of photos are supported:

  • JPEG
  • PNG

The ECG must meet the following requirements:

  • ECG recording must contain a mm-grid
  • the leads must be in a horizontal position on a photo
  • all base-leads must be of equal length, and must not represent less than 2500 ms or more than 10000 ms
  • all leads must be printed or displayed with the same voltage gain and paper speed across one ECG
  • the ECG must only include 12 leads that are related to one ECG, and no other measurements whatsoever, except the rhythm-leads
  • all leads/signals must not have empty parts, i.e. they are printed from start to finish
  • all leads/signals must have non-zero values, i.e. when a lead is not attached, diagnostics results might be affected
  • ECG leads must be represented on a bright background, the grid color must be distinguishable from the background and the leads printed with a dark color

8.1.3. Unsupported ECG formats and characteristics

  • Cabrera format
  • ECG recording does not contain a grid
  • grid is not present behind every recorded lead
  • grid is partially missing (printer error, faded ink, damaged paper, gaps in the grid, among others) or barely visible
  • grid has other granularity than 1 mm x 1 mm squares and has no/barely distinguishable lines forming 5 mm x 5 mm squares
  • any of the leads is shorter than 2500 ms or longer than 10000 ms
  • at least one lead has no activity measured or is missing
  • leads are partially missing on the photo for more than 5 mm
  • leads are barely visible
  • leads are crossing other leads for more than 5mm
  • leads are not printed alongside the horizontal grid lines
