This comprehensive book replaces Dr. Friedman's well known Outline. Organization, completeness, and lucid presentation of often complex material makes this one of the best general electrocardiography texts. Its usefulness is amplified by unusually attractive typefaces and positioning of subheads.
Readers will be grateful to Dr. Friedman for his knack of clarifying without oversimplifying the arcana of electrocardiography. Interference-dissociation, for example, becomes easier to understand because the author successfully unpeels from it long-standing terminologic encrustations. Newly understood concepts like hemiblock are equally well presented, while appropriate suspicion is cast on disproved hyperintellectualizations (eg, certain criteria for "left atrial rhythm") and statistically shaky measurements like the Macruz index.
Dr. Friedman gives ample coverage to vectorcardiography and vector interpretation of the electrocardiogram, but avoids overselling them in clinical applications. Even the subspecialist will find his discussions of left and right ventricular hypertrophy clear and comprehensive with full attention to diagnostic pitfalls.
