Amazingly, over a century after the first use of the electrocardiogram, new ECG patterns are being discovered. And in the last few decades, several new electrocardiographic phenomena and markers have emerged that are challenging to physicians and allied professionals who read and interpret ECGs such as early repolarization, ECGs of athletes, Brugada Syndrome, short and long QT syndrome, various channelopathies, and cardiomyopathies.

Internationally recognized experts discuss the most recent evidence-based information on these new observations, complemented with detailed ECG tracings, to provide essential guidance for the optimal interpretation of ECGs in the 21st century.
