Ischemic changes in exercise ECG in a hypertensive subject acutely exposed to high altitude Possible role of a high-altitude induced imbalance in myocardial oxygen supply-demand

Abstract

In the 1930–1940s Levy and coworkers administered low oxygen tension (thus simulating exposure to an altitude of about 5000 m) while monitoring ECG, in order to demonstrate coronary inadequacy resulting from imbalance between myocardial oxygen supply and demand in hypoxic conditions...
