Pharmacology in the Catheterization Laboratory

This timely reference summarizes the use, risks, dosages, interactions, and alternatives for all drugs commonly used in the catheterization laboratory. For ease of use, each chapter opens with a summary and includes cases and illustrations. Ron Waksman, MD, FACC.
