Medical Eponyms
Second-degree Atrioventricular block:

1906 – Hay kymographically recorded simultaneous jugular venous and radial arterial pulses of a 65-year-old man with a slow pulse. He observed that the a-to-c intervals of the jugular venous waves remained constant until an a wave occurred that was not followed by the c wave or a radial pulse. The pause was equal to 2 atrial pulse-wave intervals

1924Woldemar Mobitz reported ECG correlations of the abnormal jugular wave findings as originally described by Wenkebach and Hay, and classified the AV block into two types


Controversies
  • Regarding date of death: 21st March 1959 (Munks Roll); 23rd April 1959 (Lancet) and 21st April 1959 (Clinical cardiology)
  • Rare, unfounded claims by compatriots of Hay suggest he discovered both type I and II second-degree AV block
