Description
Electrocardiographs are medical instruments that measure the rhythm of heart contractions and the relative strength of different parts of the heart muscle. This portable electrocardiograph had been the property of Dr S. S. Suzman who worked in the Cardiographic Department of Guy’s Hospital during the 1940s. With a team of researchers, he studied and published on: cyanotic congenital heart disease in children; pericardial effusion, or an accumulation of fluid in the sac membrane that contains the heart; the narrowing of the aorta, or the left ventricle that distributes oxygenated blood to the body. The death of Dr S. S. Suzman was noted at the Forty-third Annual General Meeting of the British Cardiac Society held in Liverpool, 8–9 April 1965.
