John Hay (1873 – 1959) was an English physician.
Dr John Hay kymographically recorded simultaneous jugular venous and radial arterial pulses of a 65-year-old man with a slow pulse. He was the first to record a form of second degree atrioventricular (AV) block that is now better known as Mobitz type II AV block

Notable as the many academic distinctions were that came to him during his long life, his greatest achievement was the friendly warmth and youthful sincerity of his personality.Lancet 1959
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
1906 – Wenckebach ** acknowledged Hay’s report, and suggested that the pauses found in Hay’s patient were the result of both abnormal AV conduction and abnormal ventricular excitability. [Archiv für Physiologie 1906:332]
**Hay had also spent six month’s studying with Wenckebach at Freiburg.
