After setting out basic aspects of electrocardiography (ECG), Wang (cardiovascular medicine, U. of Minnesota-Minneapolis) presents and identifies typical examples of nearly all ECG entities commonly encountered in daily cardiology practice. The point is to help instill pattern recognition, point out salient features, and explain the logic behind ECG manifestations. Among the topics are a systematic approach to interpreting the ECG, intraventricular conduction defect, atrial tachycardia, electronic pacemaker, and the differential diagnosis of various wave patterns.
