1

The throb that is felt when an artery is gently compressed; the sensation of difference between systolic and diastolic pressure

PULSE

2

Difference between the heart rate determined by an apical pulse and the heart rate determined by the radial pulse; considered to be clinically significant if the difference is greater than 2

Pulse deficit

3

Recording the heart rate by listening to the heart with a stethoscope; the most accurate pulse that can be taken

Apical pulse

4

Occurred when blood flows meets resistance to flow; measured in mmHg as the force exerted on the blood vessel wall by the blood within the vessel

Blood pressure

5

Noises made by blood flowing turbulently through a partially compressed artery

Sounds of korotkoff

6

Top number of blood pressure

Systolic

7

Bottom number of blood pressure

Diastolic

8

Delays electrical impulses, which allows the atria can finish their contraction before the ventricles are stimulated

Av node

9

Delivers electrical impulses to the ventricular myocardium and to the papillary muscles

Purkinje fibers

10

Pacemaker of the heart

Sa node

11

Transmits impulses through the interventricular septum

R and L bundle fibers

12

Directs electrical impulses from the SA node to the AV node

Internodal pathway

13

Only place in the heart where electrical signals can pass from the atria to ventricles

AV bundle

14

A period of contraction of a set of heart chambers

Systole

15

Period of relaxation of a set of heart chambers

Diastole

16

Heart rate higher than 100 ; significant when increased rate is occurring when person is at rest

Tachycardia

17

Heart rate slower than 60 bpm; can be non pathological if the heart is so highly conditioned that the stoke volume compensated for the low heart rate to maintain cardiac output

Bradycardia

18

Disorganized spread of electrical signals that lead to disorganized myocardial contractions that are unable to to effectively move blood though the heart

Fibrillation

19

An abnormal heart sound caused by the abnormal movement of blood within the heart. Often indicates a valve problem or septal defect

Murmur
