Query: Heart Disease Review and Assessment

I took my review and assessment in 1998, when I was a resident of internal medicine and prepared for examination in Cardiovascular diseases. I'd have problems to answering the questions, but the answers, sometimes quite detailed was very important to understanding the subject. "Knowing the right answer is useless if you don't understand why it's the right answer". The time propoused for each question: 2 min and half wasn't enougth. I think that you will spend a lot of time to review this book. Take a special attention to part I in the examination of the patient, and if you have time look for the clinical cases.
