Cardio Flashcards
(51 cards)
Fever
> or equal to 100 deg. (often stated as 100.4)
Rectal temp
Higher than oral by 1 degree
Axillary Temp
Lower than oral by 1 degree
Tympanic Temp
Higher than oral by 1 degree
Measures core temperature
Base
R & L interspaces next to the sternum
Great vessels originate
Apex
Inferiolateral tip of left ventricle
Produces apical impulse which is normally the point of maximal impulse (PMI)
Tricuspid
4th or 5th ICS
Atrioventricular Valces
Mitral
Tricuspid
Semilunar Valves
Aoritic
Pulmonic
Murmur
Heart sounds that are produced as a result of turbulent blood flow
Thrill (or vibration)
- Palpable murmur
- May be caused by vigorous blood flow through any narrowed opening
- ->aortic stenosis, ventricular septal defect
Lift (or heave)
- When cardiac impulse (apical impulse) feel more vigorous than normal and can be felt through the chest wall
- Causes: Ventricular hypertrophy, hyper dynamic ventricular activity
Precordium
- Front of chest wall that overlays the heart and epigastrium
- Examine w/ pt supine or in left lateral decubitus position
Apical Impulse
- Represents pulsation of the left ventricle
- Normall the PMI
- Located @ 5th ICS in MCL
- If lateral to MCL or larger than 2.5 cm diameter= Suggest left ventricular hypertrophy
Apex Beat
- Palpable in 25-50% of health adults in supine
- Palpable in 50% in left lateral decubitus position
Right Ventricular Hypertrophy
-Show as “parasternal lift” @ LSB
Diaphgragm of Stethoscope
-Best for high pitch sounds (S1, S2)
Bell of Stethoscope
-Best for low pitch sounds (S3 or S4, if present)
Auscultation of cardiac locations
Aortic- 2nd ICS, RSB Pulmonic- 2nd ICS, LSB 2nd Pulmonic- 3rd ICS, LSB (Erb's Point) Tricuspid- 45h and 5th ICS, LSB Mitral (apex)- 5th ICS, MCL
Systole
- Contraction of ventricles
- Aortic and pulmonic valves forced open and blood is ejected into arteries
S1 heart sound
- Closure of AV valves: Mitral and tricuspid vlaves
- Produces “lub” sound
- Best heart @ Apex
- Carotid upstroke occurs just after S1
Diastole
-Relaxation of the heart
S2 Heart sound
- Produces “Dub” sound
- Closure of Aoritic and Pulmonic Valves
- Best heart @ base
- Carotid upstroke occurs just before S2
- -S1–>Carotid upstroke–>S2
Normal split during inspiration
- A2 heard first, then P2
- “Physiological splitting of S2”
