O’Keefe ECG has been a great resource for me throughout my training. It does a wonderful job of testing residents’ and fellows’ knowledge of interpreting ECGs using real-life patient examples for a more realistic immersion, complemented by clear and concise explanations. This website is an invaluable resource for all residents. Thank you, Dr. O’Keefe!

Fantastic source for ECG review. Good for all levels of training! I especially like how easy it is to review the explanations on the different morphologies that present themselves on ECG. The interface is very professional and easy to use. Would highly recommend!

This website is a fantastic resource for learning ECGs. I got to know about this website from CV fellows at my hospital, and I feel this is a great learning tool for all IM and EM residents. The EKGs on the website are of high definition, which allows for clear image quality even when zooming in. The option to solve random ECGs or review the classic cases step-by-step makes this very unique. I am looking forward to more exciting updates on the websites.

Excellent online resource for trainees with over 300 practice ECGs. Works perfectly in tandem with the complete guide to ECGs book by Dr. O’Keefe. Highly recommended for fellows and residents interested in Cardiovascular Medicine.

O’Keefe ECG is a great online learning tool for ECGs. I have come across other ECG resources but this one is unique and better because of its interactive nature. The scoring system not only solidified fundamental ECG concepts but also familiarized me with the format of cardiology boards. After using this resource, I feel much more comfortable in commenting on ECGs in my everyday practice. Apart from cardiology fellows, I would recommend this resource to residents who have a special interest in cardiology.

O’Keefe ECG is a wonderful resource for studying and understanding EKG. It is a complete package and I have applied the knowledge I learned from this resource during my night rotations as an intern. Highly recommended for residents.

O’Keefe ECG is an excellent source that has helped me perfect my ECG reading skills. I’ve been told many times that the best way to learn ECGs is repeated exposure. This site offers exactly that with detailed explanations. As a medical student, the nuanced discussion of the various ECG abnormalities and rhythms has made me more comfortable reading ECGs on rounds. This is a great resource for anyone who wants interactive feedback integrated into their learning!

Excellent source of high yield ECGs for the boards. User friendly interface and representative of what to expect on test day. Explanations not only guide you as to the correct answer choices, but put it in clinical context. When I used ECGsource, it had some inaccurate information and issues with overcoding that became confusing. This is clear and accurate and a nice supplement to the O’Keefe ECG book.

There are (currently) many online resources to choose from, when deliberating on the most ideal study method for the ECG component of the CV Disease Boards. Dr. O’Keefe’s ECG assessment platform outshines all others – both in the meticulous style by which all ECG criteria are succinctly summarized but (also) by means of the diversity of the cases presented to the viewer. As a trainee, I have found this resource the most ideal for rapid-pace studying and am confident that this will provide me with the greatest potential to excel on the upcoming board examination. I would strongly encourage all CV Disease fellows as well as re-certifying health providers to sample this site.
