Papers from Cardiostim ^88 (date and place of the symposium are unstated). The atrium has been the focus of increased interest in recent years because of numerous experimental studies that have brought a better understanding of the mechanisms of excitability, and because the atrium seems to be an excellent model for the study of the electrical organization of the heart. Contributors here discuss progress in experimental and clinical electrophysiology and clinical and drug management. Annotation copyright Book News, Inc. Portland, Or.
