Pattern recognition is an important learning tool in the interpretation of ECGs. Unfortunately, until faced with a patient with an arrhythmia or structural heart disease, pediatric practitioners generally receive limited exposure to ECGs. The ability to clearly distinguish an abnormal ECG pattern from a normal variant in an emergency situation is an essential skill, but one that many pediatricians feel ill-prepared to utilize confidently. In Pediatric ECG Interpretation: An Illustrative Guide, Drs. Deal, Johnsrude and Buck aim to address this issue by illustrating many of the ECG patterns a pediatric practitioner is likely to encounter. ECG illustrations with interpretations are presented in several categories: normal children of all ages, acquired abnormalities such as hypertrophy or electrolyte disorders, and common congenital heart disease lesions. Later sections cover bradycardia, supraventricular and ventricular arrhythmias, and a basic section on pacemaker ECGs. Simple techniques used to interpret mechanisms of arrhythmias are described as a resource for practitioners in cardiology, adult electrophysiology, or pediatrics who may not have a readily accessible resource for these ECG examples.
