using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle (heartbeat).

Changes in

the normal ECG pattern occur in numerous cardiac abnormalities, including cardiac rhythm disturbances inadequate coronary artery blood flow and electrolyte disturbances (such as hypoalemia and hyperalemia).

An electrocardiogram

(ECG) is a simple test that can be used to check your heart's rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats.

represents the depolarization of the ventricles; and the T wave, which represents the repolarization of the ventricles.

the body surface. Any pair of electrodes can measure the electrical potential

difference between the two corresponding locations of attachment. Such a pair forms a lead. However, "leads" can also be formed between a physical electrode and a virtual electrode, known as the Wilson's central terminal, whose potential is defined as the average potential measured by three limb electrodes that are attached to the right arm, the left arm, and the left foot, respectively.

due to work done by the heart by pumping blood through the circulatory system. Used without further specification, "blood pressure" usually refers to the pressure in large arteries of the systemic circulation.

numbers.
The first number, called systolic blood pressure, measures the pressure

in your blood vessels when your heart beats.
The second number, called diastolic blood pressure, measures the pressure in your blood vessels when your heart rests between beats.
If the measurement reads 120 systolic and 80 diastolic, you would say, “120 over 80,” or write, “120/80 mmHg.”

as BP!!!!!

as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is

persistently elevated. High blood pressure typically does not cause symptoms. Long-term high blood pressure, however, is a major risk factor for coronary artery disease, stroke, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia
