Everything about Bernard Lown totally explained
Bernard Lown,
M.D. (born
June 7,
1921) is the original developer of the
defibrillator and is an internationally known
peace activist. He was awarded the 1985 Nobel Peace Prize for his work against nuclear proliferation.
Born in
Lithuania, he emigrated at age 13 with his parents to the US, initially to Maine shortly before the outbreak of World War II, and subsequently studied to become a specialist in
cardiology.
Education
Bernard Lown attended the
University of Maine in Orono and majored in Zoology. He graduated from the institution in 1942 and wrote an Honors Thesis entitled "Multiple Alleles in Sex Determination of the Parasitic Wasp, Harborbracon."
Development of the defibrillator
Up until the late 1950's,
fibrillation of the heart could be treated only by drug therapy. In 1956 American cardiologist
Paul Zoll published a paper describing resuscitation of open-heart surgery patients by means of a 110 volt alternating current electric shock (derived from a wall socket) and conducted to the sides of the exposed heart by metal plate "paddles". While being an advance in emergency resuscitation, the technique was later to be shown to be both damaging to the heart muscle and of unpredictable effectiveness in reverting ventricular fibrillation.
In 1959, Lown, aware of the Zoll paper and of the complications resulting from the alternating current method, commenced
animal research in an endeavour to define a less traumatic and more effective form of electric shock.
This work resulted in what became known as the "Lown waveform"; a single heavily damped
sinusoidal waveform with a half cycle time of approximately 5
milliseconds. The waveform was produced by charging a bank of
capacitors to about 1000 volts, then discharging the capacitors through an
inductor to deliver the waveform to the heart.
Following the research findings, Lown contacted engineer
Barouh Berkovits of the American Optical Company, who produced a clinical prototype defibrillator (often referred to as a "cardioverter") which became the basis for further technological evolution. The original machine, weighing some 60 lb (27 kg), delivered the Lown waveform at energy levels up to 100
joules for exposed heart application, and 200–400 joules for transthoracic application.
Peace activist
In 1960 he was one of the founders of
Physicians for Social Responsibility and later the co-founder of
International Physicians for the Prevention of Nuclear War. He also founded two organisations, SATELLIFE and ProCOR, which provide health information and assistance to developing countries.
International Physicians for the Prevention of Nuclear War was awarded the 1985 Nobel Peace Prize.
Bernard Lown is currently Professor of Cardiology Emeritus at the
Harvard School of Public Health. He and his wife Louise have three children.
