A new technique, utilizing a hydrogen-sensitive, platinum-tipped wire electrode introduced percutaneously by a no. 18 Cournand needle into the brachial vein and flow directed into the right heart chambers and pulmonary artery, has greatly simplified the detection of left-to-right intracardiac shunts. The electrode position is identified by intracavitary electrocardiographic monitoring. Electrical potential, created by contact of inhaled hydrogen with the platinum tip produces characteristic electrocardiographic deflections when left-to-right shunts are present.
Catheterizations in 182 patients have yielded 86 positive, 115 negative and 3 equivocal shunt curves. Fifty-three instances (45 positive and 8 negative) have been confirmed by cardiac catheterization and
