Modern EKG Machines
If you have ever had an electrocardiogram test performed,
you know how quick and easy of a test it is. It
wasn’t always this way however. The EKG machine
has evolved for over 100 years from a revolutionary
(yet primitive) machine to the technological
miracle that it is today. Read on for a brief history
of the EKG machine.
EKG
machines have come along time since the 1800’s.
Back in the day they used to be huge immobile machines
used to measure heart signals. Now, they are small
and lightweight, and can be transferred easily.
EKG machines
use electrodes that are attached to your body to
measure your heart signals and detect signs of trouble.
When EKG machines were first invented, electrodes
were not used. Instead, patients were required to
place their hands and feet into sodium chloride
baths, a conductive method for the faint electric
impulses found in the heart. Later, electrical wires
were used to transmit heart signals to the machine;
eventually the electrodes we use now replaced these
wires.
Today most patients lie on an examination table
for their EKG
exams. If you look at photographs from the late
1800s, the patients look as though they are strapped
into an electric chair. Modern methods have made
the procedure much more simple, safe, comfortable
and accurate.
Some doctors prefer that patients perform a stress
test. This occurs when the electrodes are attached
while the patient is performing moderate exercise.
Some patients may be asked to ride a stationary
bike or walk on a treadmill. Exercising while attached
to the EKG machine may often give the technician
or your doctor a better understanding of your heart-function
pattern during physical strain.
