The History of the EKG Machine

An EKG machine measures the electrical activity of the heart. It displays this activity by drawing waves on a piece of paper that is either displayed on a screen or drawn on a piece of paper that runs through a machine.
• Late 1700’s – The first step in the development of the modern electrocardiograph machine was the creation of a machine that could sense, but not measure, electric current. This machine was called a galvanometer.
• 1786 an Italian physician, Dr. Luigi Galvan, discovered that skeletal muscles worked by producing electric current. In
• 1842 Dr. Carlo Matteucci working at the University of Pisa discovered that there is an electrical current that comes with each heart beat in a frog.
• Mid 1800’s a machine called the “Rheotome” was invented that could now measure this electrical current.
• 1872 – further refinements to this Rheotome led to a machine devised by Gabrrile Lippman  of the “capillary electrometer”.
During this time, a British physiologist, Augustus Waller, was able to record the first human electrocardiogram that using this technology with electrodes placed on the chest and back of a patient. This demonstrated electric activity taking place before ventricular contraction. In
• 1893 – Dr. Wilhelm Einthoven, a Dutch physiologist,  refined the capillary electrometer to show five deflections in the electrical current passing through the heart. The five waves were initially called ABCDE, but were changed to PQRST after a mathematical correction was made to compensate for the inertia in the capillary tube. He used the phrase “electrocardiogram” for the first time at a meeting of Dutch physicians.  In
• 1901 – Dr. Eintoven he developed a string galvanometer, a more sensitive machine. He  was awarded the Nobel Prize in Medicine and Physiology for his invention of the electrocardiograph.
As time passed, the electrocardiograph machine became much smaller and much more accurate. In 1903 it weighed 600 pounds and by 1930 it weighed about 30 pounds. The importance of an electrocardiograph was recognized as being essential in diagnosing cardiac from non-cardiac pain and able to help diagnose a myocardial infarction or a heart attack. Today we use a 12 lead electrocardiogram as a major tool in diagnosing heart disease. The machine today weighs just a few pounds and is an essential tool in diagnosing diseases of the heart.

#TBT — The History of Magnetic Resonance Imaging or MRI

Physicians often send patients for Magnetic Resonance Imaging or MRI’s to help them diagnose certain medical conditions, but do you know what an MRI is?

mri-300x200In 1977 the first human scan was performed in a prototype MRI machine. An MRI is a computerized map of harmless radio signals emitted by the human body. MRI works by creating a strong magnetic field where protons in the nucleus of the hydrogen atoms are magnetized. It is excellent for viewing soft tissue and seeing any defects that may be present.

The rotating magnetic field was discovered by Nikola Tesla in 1882. This eventually led to the definition of the Tesla Unit which describes the strength of a magnetic field. MRI machines, which were developed almost a century later, are calibrated in Tesla Units. The stronger the magnetic field, the stronger the amount of radio signals that are given off by the body’s atoms. The stronger the radio signal will lead to a better quality of the MRI image.

Flushing Hospital Medical Center’s Department of Radiology offers a wide variety of state-of-the-art diagnostic and specialty services performed by Board Certified, Fellowship trained, Radiologists, and highly trained licensed and registered Technologists.To schedule an appointment for a MRI test or for more information about the MRI, please call 718-670-8851.

#TBT — The History of Eyeglasses

Over 60 percent of the adult population in the United States today wears eyeglasses. Modern day eyeglasses have their roots that date back more than 1000 years. In the middle ages Monks were known to use reading stones that were glass spheres, sometimes filled with water,  that were placed on top of objects in order to magnify them. The first documented use of eyeglasses was attributed to being developed in Italy.  In the 13th century Venetian glass blowers made the first solid glass lenses that were held by frames and that were a primitive version of modern day wearable eyeglasses.
In the 17th century eyeglasses started to be made that could correct vision. Glasses could be made with either concave lenses, for nearsightedness, or convex lenses for farsightedness. Benjamin Franklin invented bifocal lenses in 1784. Glass was the material used in the production of eyeglasses for centuries until the latter part of the 20th century when plastic became widely used in eyeglasses as it was lighter and safer than glass. Now many eyeglasses are being made from polycarbonate which is lighter still and more resilient to scratches.

#TBT FHMC Doctor Discovers First Outbreak of West Nile Virus in NYC

Dr. Deborah Asnis, Director of Infectious Disease at Flushing Hospital Medical Center, discovered the first outbreak of West Nile Virus in 1999.  After noticing uncommon symptoms among five of her admitted patients, she played the role of detective and used her knowledge as a doctor to identify the cause of these more than flu-like symptoms in her patients.

Thanks to Dr. Asnis, the city of New York has taken precautions against the spread of the West Nile Virus by spraying neighborhoods to prevent increased activity of infested mosquitoes and the spread of their larvae.

March is National Women’s History Month

Did you know that Flushing Hospital Medical Center was founded in 1884 by a group of community women who set up a room with one bed in a rented house? Today the hospital is a 293-bed voluntary, not-for-profit teaching hospital. The medical center, located in the city’s most culturally diverse borough, has served the health care needs of the community for more than a century, and has, over the years, become a solid and vital part of the infrastructure of the city itself.
