The Electrocardiograph (EKG or ECG) was said to be created in 1877 by Augustus Waller. This medical breakthrough records and interprets the electrical activity of the heart muscles and measures the rate and regularity of the heartbeat. With each heartbeat, an electrical current pumps through the organ. This pulse makes the heart contract and push blood to the rest of the body.
Electrodes are strategically placed on the skin of the chest, legs and arms. The skin has to be clean and in some cases any hair on the skin may need to be clipped or shaven. The standard number of electrodes used for a diagnostic test is 12-15. Although for basic monitoring sometimes as little as 3 are needed. Through the electrodes, the EKG records each of the heart’s electrical pulses. Each pulsation is transmitted to the skin when nerve centers sense the contraction and relaxation of the heart muscle.
An accurate EKG reading is taken through a sequence of three waves named P, QRS, and T. The P wave, a short, low amplitude wave, marks the impulse of the heart’s atria, which receives blood from the veins. The high amplitude QRS wave measures the ventricular activity and the slow forming T wave shows ventricular renewal.
An EKG is painless. The test examines outgoing electrical impulses and therefore does not create an electrical shock. Before taking an EKG test, inform your doctor of any medications you may be taking. It is also recommended that patients do not drink cold water immediately prior to an exam because it may cause changes in the T wave.
The electrocardiograph can be used while the patient is either laying still on a table or during an exercise electrocardiography, which examines the heart while under stress. The patient undergoes a series of physical tests, such as running on a treadmill, to evaluate the heart’s response with the increase demand for oxygen. If there are any abnormalities in any of the waves’ duration, amplitude or direction, doctors will then use other tests and clinical observations to conclude a diagnosis. The EKG is very helpful in determining whether or not chest pain or palpitations is an indication of heart disease.
