High altitude, indigenous origin, and continuous cardiac monitoring.
Tape monitoring of the electrocardiogram among ambulant individuals with and without cardiac disease has been practicable for some years now. It has, however, found greater acceptance and utilization in diagnosis, early detection of silent ischemic heart disease (17), and the evaluation of the effectiveness of different dysrhythmia treatment modalities than as a means to examine differences in cardiovascular response to environmentally stressful situations. This study illustrates its practicability under field conditions substantially more rigorous than in most prior uses, and its applicability to our further understanding of the cardiovascular changes associated with adaptation to the hypoxia of altitude.
