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.

本书提供了150幅12导连心电图（ECG）和心率条带，每一个都伴随着一个临床病史和问题。再建全部ECG并根据病史对其进行学习应当能够给出答案。在每个案例的后面，通过描述ECG的主要特征以及临床理解和一个“应该做什么”的章节，对其进行了解释。病例按照难度进行评级。

The electrocardiogram (ECG) can be a great leveller in medicine. It is common to see various combinations of medical students, nurses, junior doctors and specialists huddled around an ECG, debating what it shows.

* A new page size allows the presentation of the 12-lead ECGs across a single page for clarity. * Many of the new cases incorporate a selection of chest X-rays illustrating the different appearances that are associated with various cardiac conditions.
