this book has been reduced to a level that non-specialists can easily digest. We've removed most of the mystery surrounding the techniques, medication, and equipment involved in diagnosing arrhythmias. What's left is an enjoyable (some say "fun to read") booklet that is essential for better diagnosis and treatment. The book covers the three most common tachycardias: narrow complex regular, narrow complex irregular, and wide complex. The last section illustrates a series of patient cases with their attendant rhythm strips. You are asked to review the facts and make a diagnosis.
