This ECG Guru website exists for the purpose of sharing teaching resources with anyone who teaches ECG or Cardiology classes.  It can be difficult to find non-copyrighted and free images to use in presentations.  Often, those resources that are available are too small to reproduce well for a handout or projector.  Our website seeks to fill this gap to make it easier for more people all over the world to receive ECG education.

Those of you who have followed the ECG Guru for a while are very familiar with the work of Dr. Ken Grauer, M.D.  He is a generous contributer to the ECG Guru website, and functions as our official Consulting Expert.  He has published many books and e-publications which are (in our opinion) some of the BEST ECG references available, and he has worked hard to keep them low priced to make them available to all of us.  He also offers seemingly endless ECG knowledge and insights for FREE, via this website, his own website, and social media.

If you are a teacher, watching a masterful teacher present your topic can help you develop your style, and increase your own knowledge of your subject.  We don't all have the opportunity to attend live classes by the real ECG Gurus of the world, but many of them are now making FREE video lectures available to all of us. Even if you are not an instructor, for many of us, hearing and seeing the presentation is a more effective way to learn than just reading.    

This is an ECG I performed a couple of years ago on an asymptomatic 83-year old man as an outpatient procedure. 

The computer interpreted this as:  "Marked sinus bradycardia [with] Frequent Premature ventricular complexes".  IS THE COMPUTER CORRECT?  Is there more than one plausible interpretation?  What is the differential diagnosis?
