How exactly does the EKG machine work?

Answer 1

<>An EKG (or ECG) takes sequential readings of the electrical signal generated by the heart. It does so using a series of electrodes: 1 is placed on each limb and readings are taken from arm to arm and arm to leg (a total of 6 readings). 5 electrodes are placed across the chest and each of those readings recorded. The 12 readings (a 12-lead EKG) give different views of the electrical conductivity of the heart and can be interpreted by a trained reader to divulge a number of different problems.

Answer 2

An electrocardiogram (ECG or EKG) is the pattern of the electrical changes in many cells caused by waves of depolarization and repolarization in the heart. Moving charges in the heart produce current movement throughout the body fluids. There are three things the doctor will look at when looking at an ECG, a P wave = atrial depolarization, the QRS complex = ventricular depolarization (masks atrial repolarization) and the T wave = ventricular repolarization. A ECG is useful in diagnosing defects in impulse propagation, but gives no information about mechanical defects (ex. valve problems). If your having heart palpatations, then there will be a problem with the electrical activity of the heart, which is read on an ECG.

Answer 3

EKG-ELECTROCARDOIGRAM

The EKG machine records the electrical inpulses of the heart. Your heart "runs" on electric. Magnesium, potassium, cloride, etc., make up the chemicals used to cause an electrical charge. Thus if your potassium is low, etc., you could have fluttering of the heart, etc., A simple blood test for "electrolytes" tells how everything is running and if the levels are good. On a hot day you sweat a lot and loose a lot of fluids and sometimes get dizzy, this is why everyone tells you to drink plenty of fluids, gatorade, etc.

Anyway, the electrical impulses are recorded onto special graphing paper that looks something like a ricther scale for earthquakes. Depending on how far apart the "waves" of the heart are, they give a record of the condition, strength, etc., of your heart. One can even tell WHERE a heart attack has happened in the heart and how long ago it happened. Hope this helps.

Answer 4

The machine is used to record the electrical activities of the heart.
There's electrical activities in heart conducting fibres and heart muscles.
The machine reocrd the amplified (by the machine) electrical activities of heart which travel from the heart through the chest wall muscles which finally reach the skin.(which is recorded by electrodes on the skin)
To make conduction better, use the water-based gel in between the electrodes and skin.
There's 3 electrodes in the limbs and 6 electrodese on chest wall which are used to record the electrical waves.
As the electrical activities is created by positive and negatives ions in the blood, changes in electorlytes cause changes in ECG/EKG as well. And the muscular activities of the chest wall can effect the ECG/EKG record, as the waves from heart travel through muscles of the chest wall.
