150 ECG Problems [PDF ebook] 

This book offers 150 12-lead ECGs and rhythm strips, each with a clinical case history and question. The full ECG is reproduced and a study of it with the case history should be enough to give an answer. On the back the case is examined, with a description of the main features of the ECG along with a clinical interpretation and a "what to do" section. The cases are graded in difficulty.The unique page size allows presentation of all 12-lead ECGs across a single page for clarity. Several of the cases incorporate chest X-rays and coronary angiograms illustrating the appearances that are associated with various cardiac conditions. All the cases are graded in difficulty and are cross-referenced to the new editions of ECG Made Easy and ECG in Practice for further information. For this Fourth Edition over 30 new ECGs have been included, mainly to provide clearer examples, though the book deliberately retains some technically poor records to maintain a ‘real-world’ perspective..
