Flashcards in Unit 3 &4 sec 1 Deck (16):
1

S3

Vibration of ventricular walls from frapid filling occurs during diastole
Normal in healthy children and adults up to 40yrs
After 40yrs indicates illness-left ventricular valve
Heard best at apex of heart
Sounds like Ken-tuc-ky
S1,S2,S3

2

S4

Atrial gallop
Caused by the vibration of the heart valves & ventricular walls
Normal in healthy adults abnormal in children& young adults
Sounds like Ten-nes-see
S4,S1,S2

3

Dysrhythmia

Abnormal
Early or late be3at or missed beat
Threatens the heart's ability to provide cardio Output

4

Heart Mumurs

Extra Sounds
Distingushed from heart sunds by longer duration
Increased blood flow across a normal valve
Flow across irregulaer valve or into an enlarged heart chamber
Backflow throughh an insufficent valve that fails to close
Sound: Swishing & blowing souns
Intensity of sund is related to rate of blood flow

5

Normal Heart Sound

S1-lub
closing of artrioventricular valves
high pitch-kinda dull
Tricuspid & mitiral
S2-dub
closing of semilunar valves
Pulmonary & Aortic
shorter than S1

6

Heart

Strongest organ
Avg. 70-80 bpm
Hollow muscular organ
Located left of the midline, between lungs
Base -upper portion
Apex-lower portion-don't get confused apex means point but not in this case

7

Cardiac Output

Amount of blood pumped per minute
SVx Pulse rate(HR)=CO

8

Stroke Volume

The amount of blood ejected by the left ventricle at each heartbeat.
Avg: 70ml

9

Apical Pulse

Hear over 4 & 5 intercostal spaces left of midline, that is the point of maximum impulse(PMI)

10

PMI

Point of maximum impulse is between 4 & 5 intercostal space to hear

11

Hear S2
Base of heart

Aoritic Area
2nd ICS-right of the sternum
Pulmonic Area
2nd ICS-left side of sternum

12

Hear S1
Apex of heart

5 ICSl-left of sternum
Left of midclavicular area( striaght down from nipple)

13

Pulse Site's

Temporal-not on adults but on infants
Carotid
Brachial-little finger side
Radial-thumb side
Femoral-press deeply
Popliteal-press deeply
Posterior tibial-back of ankel
Dorsalis pedis-top of foot- follow ridge between big toe &2nd toe up to top of foot

14

Pulse rate

# of piulsations felt over peripheral artery or heard over apex. Adult 60-100

15

Bradycardia

slow heartbeat-below 60

16

Tachycardia

fast heartbeat-above 100
