Possibilities, limitations, and technique for the study of regional myocardial perfusion in man by Xenon-133.

abstract：:Although the existence of t-tubules in mammalian cardiac ventricular myocytes has been recognized for a long time, it now appears that their structure and function are more complex than previously believed. Recent work has provided evidence that many of the key proteins underlying excitation-contraction coupling are l...
