EDITORS' INTRODUCTIONS
For some years I have wondered what it would be like to gather a small group of outstanding investigators and to place them in a room for a few days with nothing to do but talk to one another. Therefore, I was elated when Y oram Palti telephoned me two years ago with just this plan in mind. The format we agreed to was simple-to bring such a group of investigators to the Rappaport Institute of the Technion, to closet them in a conference room, and to set aside a period of time during which each could express his views about what he considered to be a critical aspect of his research. No slides would be permitted-only verbal communication and liberal use of a blackboard. Moreover, interruptions would not only be permitted but also encouraged; after each investigator began to talk, others in the group could interrupt at will. We felt that if the group dynamics worked out appropriately, then no one would be able to complete his planned remarks, but the resultant discussions would lead us to new insights and directions concerning research.
Since the order of the meeting was obviously based on chaos, we belived that some form of structure had to be imposed to maintain an overall focus. The first attempt at structure was the theme of the meeting itself: Lethal Arrhythmias in the Setting of Myocardial Ischemia and Infarction. Certainly, this is an important topic, but having settled on it, we decided to interpret it in the loosest possible sense. That is, rather than consider arrhythmias alone, we included a diversity of factors that might modulate them: neuroendocrine,

metabolic, and ionic. This approach, in turn, required the participation of a diversity of investigator interests and skills. Hence, we invited clinical and basic investigators whose research interests ranged from studies of membrane patches to studies of the patient. This diversity of interests concerned us. How often have we attended meetings where the clinical scientists talk only to each other, the basic scientists do the same, and there is a minimum of interaction? This concern led us to the second aspect of the structure; that is, all participants were requested to remain in the meeting room throughout the duration of the meeting. It is of interest that the request was followed, with a minimum of comings and goings, and clinically and basically oriented individuals found a variety of ground for common discussion. As for the third aspect of the structure, you are holding it in your hands. We believed that to prepare for the meeting, it would be helpful if each individual would write a position paper. We requested an essay, not highly illustrated or referenced, and not necessarily balanced in terms of one's field of research. Ideally, we wanted it to highlight exciting areas of investigation now occurring and to stress directions for future research. These papers were distributed to all participants, one month before the meeting, and provided an initial framework for the participants' consideration.
No tapes or other permanent records were made at the meeting, except for the continual taking of notes by all participants. Based on the discussions and ideas generated, as well as the active participation by all present, my prejudice is to think that the meeting was successful. This book, which contains only a fraction of the ideas stated, nonetheless, serves as an indicator and partial transcript of what transpired.
There are many people for me to thank: first of all my co-editor and co-director of the meeting, Y oram Palti, without whose interest the meeting could never have been conceived and carried out; second, the Rappaport family and the Technion, for their support of the meeting; third, Haia Ganzarski and Rina Banks, whose tireless administrative efforts were required to arrange arrival, departure, and all that occurred in between. Finally, and most important, I would like to thank the participants themselves, for their efforts in preparing for the meeting (including submitting their papers for this volume), for their willingness to share their ideas and fantasiesarmed only with blackboard and chalk-before a highly critical cohort of peers, and without whose abilities at communication and criticism there simply would have been no meeting.

The research program of the Rappaport Institute for Research in the Medical Sciences gives priority to the cardiovascular system. Since this area is staffed at the Institute by relatively young scientists, we asked Mike Rosen for assistance with its development. Mike provided us not only with developmental guidance, but also served as the driving force and spirit behind the organization of the second Rappaport Symposium, which was dedicated to Lethal Arrhythmias Resulting from Myocardial Ischemia and Infarction.
The symposium topic, which is of prime medical importance, is of special interest to our cardiovascular researchers, most of whom are concerned with cardiac electrophysiology and/or ischemia. I believe the panel of scientists that assembled here represented the ultimate researchers in their fields and were well balanced between clinical and basic sciences. With his charming but firm leadership, Mike managed to conduct the meetings to use the talents, experience, wisdom, and humor of the participants to the utmost. Thus, I feel that we have experienced a stimulating, informative, and at the same time, pleasant meeting.
I am taking this opportunity to thank the participants in the symposium for their scientific contributions and for the friendship they extended to us. I am sure that I speak for all of them when I thank the Institute staff that helped to organize the symposium. I especially want to thank the Meeting Secretary Haia Ganzarski who put forth tireless efforts, used good taste, and exhibited high spirits to ensure that every moment was an enjoyable one.

I hope that the meeting will encourage further interactions and cooperation among all the participants and will benefit each individual's scientific progress and the progress of the medical community as a whole.
Finally, we are grateful to the Rappaport Family for supporting this symposium among their many projects that support medical science in Israel and elsewhere.
