This post is here just because I happened to watch the EACVI video on speckle tracking. I don’t recommend it.
Primary care clinicians need to know what speckle tracking is as your echo reports from your echo lab should now contain an evaluation of the Global Longitudinal Strain For Left Ventriclular Function.

I just wanted to have an idea of what speckle tracking is and here is what I found:
Here is a YouTube video from 123sonography.com which is an introduction to the terminology.
Published on Oct 30, 2018Learn why you should use Speckle Tracking Imaging and where you can apply it in your practice. Find out what key experts in the field think about deformation imaging and what it will bring in the future. If you like the way we teach, sign-up for more free lectures on: https://www.123sonography.com/ultraso… The Speckle Tracking MasterClass will teach you this important modality of echocardiography. You will gain a deep knowledge of strain rate imaging and where it can be applied to use it in your clinical practice right away.
And finally, here is a link to the website, Strain rate imaging.
Myocardial deformation imaging by ultrasound / echocardiography
Tissue Doppler and Speckle tracking by Asbjørn Støylen, Professor, Dr. med.Website updated December 2018.
The next video, below, is not that helpful to me as a primary care POCUS heart practioner. I watched it as it was one of the first videos to come up on my YouTube search.
The first 31 minutes of the webinar discusses the technical aspects of speckle tracking.
At 31:00 the webinar starts a clinical discussion of speckle tracking, longitudinal strain.
Dr.Edvarsen states that we should now report global longitudinal strain as a part of our complete echo report.
Dr. Edvarsen presents a list of papers from 2015 to 2017 that includes recommendations for the use of strain:
