This ECG is from an 80-year-old lady who has collapsed or had sycopal episodes several times. The ECG comes from a Holter monitor. She has arterial hypertension and coronary artery disease. The ECG shows a second-degree, Mobitz Type II AV block. In both types of AVB, the PP intervals are usually the same.

Welcome to Dr. Andreas Roeschl, who is a cardiologist and ECG instructor in Germany.  He will have a recurring blog on the Guru, contributing his knowledge about ECG and teaching, along with ECGs from his collection.  His ECGs are digitized and beautiful quality for reproduction, and his contributions will be a great asset to any student or teacher of ECG.  Dr. Ken Grauer and I want you to feel free to ask us and Dr. Roeschl any questions you have about ECG or teaching ECG.  That is the mission of this website - to make it easier for instructors to teach.

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.
