ECG/Blood Pressure/Pulse

ECG

Stands for electrocardiogram

PR interval

The time from the beginning of the P wave (atrial depolarzation) to the beginning of the QRS complex (ventricular depolarization)

PR segment

The portion of the ECG from the end of the P wave to the beginning of the QRS complex

QRS segment

A combination of the Q wave, R wave, and S wave and they represent ventricular depolarization

ST segment

The time between the end of the ventricular depolarzation and beginning of ventricular repolarzation on the ECG ( end of QRS to the start of T wave)

QT interval

Represents the duration of the ventricular action potential

T wave

represents the repolarzation or relaxation of the ventriculars

Depolarization

the process by which the membrane potential becomes less negative and creates the generation of an action potential

Repolarzation

occurs after contraction when K+ ions flow out of the cells, which returns to resting state

Blood pressure

The force of your blood pushing against the walls of your arteries

Systole

The phase of the heartbeat when the heart muscle contracts and pumps from the chambers into the arteries

Diastole

the phase of the heartbeat when the heart muscles relaxes and allows the chamber to fill with blood

Korotkoff sounds

the series of sounds made by the blood rushing through an artery - the sounds doctors listen to take blood pressure

Pulse

the number of times the heart beats within a certain time period, usually a minute

Mostly common locations to take a pulse

Carotid pulse, radial pulse, and branchial pulse

Pulse pressure

The difference between the systolic (top) and diastolic (bottom) numbers of your blood pressure
