Who pioneered the first human electrocardiogram (ECG)?

Augustus

Desiré Waller

HH

The first electrocardiogram (ECG)

from the intact human heart was recorded with a mercury capillary electrometer by Augustus Waller in May 1887 at St. Mary's Hospital, London. The tracings were poor and

exhibited only 2 distorted deflections. Waller failed to see the potential importance of the ECG as a diagnostic

tool. Willem Einthoven perfected Waller's work and was awarded

the Nobel Prize in 1924.
