Cardiac/MS Flashcards
What are the heart layers?
Pericardium, myocardium, and endocardium
What is the pericardium?
Sac that surrounds and protects the heart
What is the myocardium?
Muscular wall of the heart. Does the pumping.
What is the endocardium?
Thin layer of tissue that lines the inner surface of the heart chambers and valves
What are the four valves of the heart?
AV (atrioventricular valves)- Open during filing phase (diastole)
Right AV- tricuspid valve
Left AV- bicuspid (mitral) valve
SL (semilunar valves)- Open during pumping phase (systole)
Right SL- pulmonic valve
Left SL- aortic valve

Pacemaker
Blood flow through Coronary Circulation
- Right atrium
- Tricuspid valve
- Right ventricle
- Pulmonic valve
- Pulmonary artery
- Lungs
- Pulmonary veins
- Left atrium
- Mitral valve
- Left ventricle
- Aortic valve
- Aorta
Pulmonary arteries carry __________ blood to the lungs.
deoxygenated
Pulmonary veins carry __________ blood from the lungs back to the heart.
re-oxygenated
Blood flow through the Cardiac Valves
Tissue Paper My Assets
Tricuspid, Pulmonic, Mitral, Aortic
Major risk factors for heart disease
Nutrition
Smoking
Alcohol Use
Exercise
Drug Use
IV drug users are at risk for
Bacterial Endocarditis
Endocarditis occurs when bacteria or other germs enter the bloodstream and travel to the heart. The germs then stick to damaged heart valves or damaged heart tissue. Endocarditis is a life-threatening inflammation of the inner lining of the heart’s chambers and valves. This lining is called the endocardium.
Orthopnea
DIB when supine/laying down
Hyperlipidema
High cholesterol
JVD
Jugular vein distention- bulging of major veins in the neck
It’s a key symptom of heart failure and other heart and circulatory problems.
Thrill
A thrill is a palpable vibration over artery (feels like the throat of a purring cat). It signifies turbulent blood flow. A thrill can accompany a loud murmur.
Lifts and Heaves
Thrust of ventricle
Bruit
A bruit is auscultated over an artery. Sounds like a blowing & swishing sound. Indicates blood flow turbulence.
__________ a Thrill.
__________ a Bruit.
Feel a Thrill.
Hear a Bruit.
What direction is used to auscultate the heart?
Listen in a “Z” pattern. Inching the stethoscope from base to apex. Use bell and diaphragm.
What are the Cardiac Landmarks for auscultation of the heart?
Aortic Valve- 2nd Intercostal Space, Right Sternal Border
Pulmonic Valve- 2nd Intercostal Space, Left Sternal Border
Erb’s Point Valve- 3rd Intercostal Space, Left Sternal Border
Tricuspid Valve- 4th Intercostal Space, Left Sternal Border
Mitral Valve- 5th Intercostal Space, Midclavicular Line
PMI
Point of Maximal Impulse
Auscultating Carotid Arteries
Ask patient to briefly hold their breath. Use bell of stethoscope. Listen for bruits.
** BELL for BRUITS **
Do NOT compress the carotid artery with the bell. It can cause an artificial bruit.
APE To Man
Aortic –> Pulmonic –> Erb’s Point –> Tricuspid –> Mitral
What is a murmur?
Gentle blowing, swooshing sound heard over heart valves
Normal heart sounds
S1 and S2
S1
1st heart sound – closure of AV valves, beginning of systole
S2
2nd heart sound – closure of SL valves, end of systole
Abnormal heart sounds
S3 and S4
S3
KEN - TU - CKY
LUB(1) DUB(2) DUB(3)
3rd heart sound – ABNORMAL – immediately after S2, when AV valves open and atrial blood goes into ventricles
S4
TEN - NE - SSEE
Hear before LUB(1)
Gallop
4th heart sound – ABNORMAL – just before S1, at end of diastole, ventricle resistant to filling
S3 sounds can be normal in
young adults & children
pregnancy
athletes
S3 sounds are abnormal in
Adults and elderly
S3 sounds indicate
Severe Mitral or Tricuspid Regurgitation
Cardiomyopathy
Heart Failure
S4 sounds are almost always __________.
Pathological
S4 sounds indicate
Indicates DIASTOLIC Heart Failure
Severe Left Ventricular Hypertrophy
Cardiac Ischemia
Uncontrolled HTN
Hypertrophic or Restrictive Cardiomyopathy
ABC’s of Heart Health
Appropriate Aspirin Therapy
Blood Pressure Control
Cholesterol Control
Lifestyle changes for Heart Health

Weight management
Arteries are used to pump __________ blood.
oxygenated
Temporal, Carotid, Arm, and Leg arteries
Veins have an __________ flow than arteries.
opposite
Jugular, Arm, and Leg veins
What is the role of veins?
Absorb CO2 and waste and carry back to heart
Retrieve excess fluid and plasma proteins from interstitial spaces and puts them back in bloodstream
Lymphatics/Lymph nodes
Cervical nodes
Axillary nodes
Inguinal nodes
Leg pulses and location
Femoral- located along the crease midway between the pubic bone and the anterior iliac crest.
Popliteal- The popliteal artery is palpated behind the knee.
Dorsalis Pedis- The dorsalis pedis artery is located on the dorsum of the foot. Palpate just lateral to and parallel with the extensor tendon of the big toe.
Posterior Tibialis- The posterior tibial pulse is palpated in the groove between the medial malleolus and the Achilles tendon.
Edema Scale
0= No Pitting
1+= Mild pitting; slight indentation; no perceptible swelling of the leg
2+= Moderate pitting; indentation subsides rapidly
3+= Severe/Deep pitting; indentation remains for a short period of time; leg looks swollen
4+= Very Deep pitting; indentation lasts a long time; leg is grossly swollen & distorted
What is DVT?
Deep Vein Thrombosis
Signs and symptoms of DVT
Unilateral Edema
Warmth
Redness (Erythema)
Tenderness (Cramping)
What should you avoid doing for DVT patients and why?
Do not massage area, use SCDs, or have patient walk.
Can cause pulmonary embolism (PE).
Venous Disease/Insufficiency
Think about WalMart
A brown discoloration occurs with chronic venous stasis as a result of hemosiderin deposits (a by-product of red blood cell degradation).
Warm, brown or red, swollen
(bilaterally)
Weeping or excoriating skin
Pitting edema
Varicose veins
Arterial Disease/Insufficiency
Pallor, cyanosis, atrophic skin, and unilateral coolness are all signs associated with arterial problems.
Slow healing (if any)
Necrosis
Cold, pale extremity
Peripheral pulses weak
Hairless
Atrophic Skin (Thin, Shiny & tight)
Dry skin
