The Patient: This ECG was taken from a 73-year-old man with a history of heart failure with preserved ejection fraction, severe left ventricular hypertrophy, Type II diabetes, and stage 4 chronic kidney disease. He also suffered deep vein thrombosis and is on anticoagulation. He has a recent diagnosis of IgA myeloma.
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.
Teaching Axis Determination
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.
A laddergram is a diagram of conduction through the heart, presented in a minimum of three tiers, one for the atria, one for the AV junction, and one for the ventricles. Laddergrams are very useful for presenting and testing your theory of a dysrhythmia. Instructors often use them to illustrate complex dysrhythmia mechanisms.
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 a derived (i.e., EASI) 12-lead ECG donated to the ECG Guru by new member "chireu". The only history they were able to provide was one of possible atrial flutter but that was uncertain. How would you interpret this ECG?
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?
This is an ECG I performed on a 65-year old man about 5 years ago. He mentioned something to me about his past medical history before we got started but, in truth, I would have recognized it had he not told me beforehand. What did he tell me and what does this ECG reveal?
Patient data: 54-year old man who recently underwent a major cardiac procedure. At first glance, this ECG may not appear to be particularly unique but a closer inspection reveals something unusual going on here.
