Symptoms of angina pectoris have been observed also in association with obvious vasomotor phenomena in the extremities, without demonstrable disease of the heart. Dr. J. Pal,1 as a result of clinical studies, considers the phenomena in the peripheral vessels as an integral part of the attack of true angina, which he includes among the vascular crises. He recognizes two typical varieties, namely, the pectoral and the abdominal.
