Developer Response
Thanks for your feedback and sorry for this delay, but good news is we now have introduced a new Pro + Family Sharing purchase option in the app that you can share with your family members.
Fix the lead configuration!
_______ _______
Clinicians are used to looking at leads in a standard configuration where we come to recognize patterns of lead combinations representing various territories. This program would great if not flawed by presenting the leads in a non standard order. This makes it annoying to use. I'll wait to make good use of it when this is fixed. Until then I'll keep looking for a better program.UPDATE: it looks like efforts to permit 3x4 display have been implemented but when exporting the ecg it reverts to the non-standard format. Getting better! Added a star!
Developer Response
Thanks for the feedback, and we will look into the exported lead configuration issue and have it fixed in the next release.
new HRV is amazing
Samurai888
Update- HRV has been included and poincare plot as a bonus, there’s no other app that takes the RR data from the Apple Watch ECG directly to do this, all while fully showing all the data used. Excellent development of this app!!
Developer Response
Thanks for your feedback. That’s a great idea and definitely something we can do! Update: Thank you for such a positive review that is exactly what keeps us going forward.
Format
djparamedic
Unsure of why the format on the Home Screen shows the ecg results? Why wouldn’t it be listed as age gender brief details if there known. And then allow us the option to play and quiz the ecg… what’s the point in taking a quiz on a strip that’s labeled afib rvr lvh lae etc ? Is there a way to hide all of that information so I can review the ecg’s without seeing that first? If not this isn’t a very good testing tool.
Same ECG Pro you know and trust.
Under the hood, ECG Pro has been completely rebuilt on a modern foundation, setting the stage for some exciting new features coming soon. Stay tuned.
As always, thank you for learning with ECG Pro.
