This is a vintage collection of electrocardiograms, which ought to be enjoyed by all who interpret electrocardiograms.
References here are few.
Emphasis is on the electrocardiographic tracing with the idea that having seen one, readers will make the diagnosis the next time. The book reviewed here has electrocardiographic examples of some very complex and interesting cardiac arrhythmias. It is a focused text and well worthwhile. Because arrhythmias can present in so many different forms, the only way to be certain of an interpretation is to understand the underlying ECG mechanism of the arrhythmia . Unfortunately, standard teaching methods can seem to divorce the theoretical knowledge required for diagnosis from the hands-on reading of ECGs.
