Dr John Hay (1873-1959) portrait Hay block

John Hay (1873-1959) was an English physician and cardiologist.

Hay was a pioneer cardiologist, best known for his early description of what is now termed Mobitz type II second-degree atrioventricular (AV) block. Born in Birkenhead, England, he was educated at the Liverpool Institute and University College Liverpool, then a constituent of the Victoria University of Manchester. After obtaining his medical qualifications in 1895–96 and an MD in 1901, Hay embarked on a distinguished clinical and academic career.

In 1906, Hay published a seminal case report in The Lancet describing a form of AV block characterised by intermittent dropped ventricular beats with constant conduction intervals—a phenomenon now recognised as type II second-degree AV block. This work, achieved without electrocardiography but using kymographic tracings of arterial and jugular pulses, was later acknowledged by Wenckebach (1906) and validated by Mobitz in 1924. Hay also provided one of the earliest pathological correlations in AV conduction block (1905), and published widely on arrhythmias, paroxysmal tachycardia, and coronary thrombosis.

Throughout his career, Hay held numerous influential roles. He was assistant physician and later full physician to the Liverpool Royal Infirmary, founded its first heart department, and served with distinction in the RAMC during the First World War. He became Professor of Medicine at the University of Liverpool (1924–1934), served on the Council of the Royal College of Physicians, and was a founding member—and later chairman—of both the Cardiac Club and its successor, the British Cardiac Society. His Bradshaw (1923), St. Cyres (1933), and Strickland Goodall (1936) lectures reflected his enduring influence on British cardiology.

Beyond medicine, Hay was a skilled violinist, artist, and beekeeper, known for his charisma, warmth, and extraordinary teaching. His artistic talents found expression in watercolours, caricatures, and hand-drawn Christmas cards. After retirement, he lived in the Lake District, where he remained intellectually and socially active until his death at Bowness-on-Windermere in 1959.

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

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.

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
