IMPORTANT NOTE:

This Ramsey Electronics kit is NOT intended for any medical usage. It is simply

for experimenters and hobbyists who wish to observe an EKG waveform using

common components and commercially available sensors. Every reasonable

precaution was used in the design and manufacture of this product to make it

an accurate monitor, but you cannot draw any conclusions from the results (you

may, however, astound your physician with your knowledge of EKG operation).

Please leave any diagnosis of illness based on the analysis of EKG’s to health

care professionals using certified equipment.

Also, we realize that our customers are experimenters and on occasion have

modified our kits to suit their individual needs. PLEASE DO NOT MODIFY THIS

KIT IN ANY WAY as you will be hooking electrodes to the human body to

monitor the EKG waveform. DO NOT EVER use a battery eliminator connected

to 110 vac power.

INTRODUCTION

It has been said “What a piece of work is man”. The complexities of the human

body and our biological systems exceed the most complex machines that we

can produce. Our nervous system and synaptic processes are still not fully

understood by the most clever scientists.

Consider the heart muscle. This delicate and complex bit of tissue can be

likened to a simple pump. Now if we take the averages, this pump moves

roughly two and one-half ounces of liquid per heartbeat. If we assume an

average heart rate of 72 beats in a minute, our heart muscle moves over a

gallon per minute, about 1900 gallons a day, over 700,000 gallons per year. If

we carry this out over a lifetime, by the time we reach seventy years of age our

heart has pumped over 45 million gallons! Not bad for a half pound pump that

is the size of your fist!

Another fascinating feature of the heart muscle is its ability to continue to beat

automatically, day in and day out, for our entire life. The heart contains a built in

pacemaker that regulates the rhythm of the muscle. This can be adjusted by

the rest of our nervous system. All these nerves “firing” cause an electrical

output that we can actually measure. That is what brought about our Ramsey

ECG1 kit.

Ramsey Anatomy 101:

Let’s take a closer look at the heart muscle and its operation. The heart muscle

contains four individual chambers, with left and right atriums and ventricles that

contract when pushing blood throughout the body.
