How to interpret the ECG: A systematic approach
A systematic approach to ECG interpretation: an efficient and safe method The ECG must always be interpreted systematically. Failure to perform a systematic interpretation of the ECG may be detrimental. The interpretation algorithm presented below is easy to follow and it can be carried out by anyone. The reader will gradually notice that ECG interpretation is markedly facilitated by using an algorithm, as it minimizes the risk of missing important abnormalities and also speeds up the interpretation. Note that this chapter is preceded by an extensive discussion in the chapter Characteristics and Definitions of the Normal ECG and the accompanying Pocket Guide to ECG Interpretation . 1. Rhythm Assess ventricular (RR intervals) and atrial (PP intervals) rate and rhythm: Is ventricular rhythm regular? What is the ventricular rate (beats/min)? Is atrial rhythm regular? What is the atrial rate (beats/min)? P-waves should precede every QRS complex and the P-wave should be positive in lead II. Common…
