Rezension

`
This book is a must for those interested in this subject matter.
'

C. Visser, Dutch Magazine on Medicine,
20, 1990

`
It was a pleasure reviewing this publication ... of interest to internists and cardiac physiologists ... this is a very important book, related to a rapidly emerging exciting technique. Reading it was both intellectually and scientifically satisfying.
