CARDIOLOGY NURSING
Assessment of the CVS
PUAN ROSDIANA RAMLI

Learning Outcomes:
At the end of the session, student will able to;
• review the anatomy and physiology of cardiovascular system.
• Taking health history for cardiac assessment.• Perform the physical examination • Outline the diagnostic test.
2
THE CARDIOVASCULAR SYSTEM
HEART’S NORMAL ANATOMY• The heart is located in the LEFT side
of the mediastinum• Consists of Three layers -
epicardium, myocardium and endocardium
3
THE CARDIOVASCULAR SYSTEM
• The layer that covers the heart is the PERICARDIUM
• There are two parts - parietal and visceral pericardium
• The space between the two pericardial layers is the pericardial space
4
THE CARDIOVASCULAR SYSTEM
• The heart also has four chambers - two atria and two ventricles
• The Left atrium and the right atrium
• The left ventricle and the right ventricle
5
The Cardiovascular System
The heart chambers are guarded by valves
• The atrio-ventricular valves - tricuspid and bicuspid
• The semi-lunar valves - pulmonic and aortic valves
6
The Cardiovascular System
The Blood supply of the heart comes from the Coronary arteries
1. Right coronary artery supplies the RIGHT atrium and RIGHT ventricle, inferior portion of the LEFT ventricle, the POSTERIOR septal wall and the two nodes - AV (90%) and SA node (55%)
7
The Cardiovascular System
2. Left coronary artery- branches into the LAD and the circumflex branch
• The LAD supplies blood to the anterior wall of the LEFT ventricle, the anterior septum and the Apex of the left ventricle
• The CIRCUMFLEX branch supplies the left atrium and the posterior LEFT ventricle

The Cardiovascular System
The CONDUCTING SYSTEM OF THE HEART
Consists of the1. SA node- the pacemaker2. AV node- slowest conduction3. Bundle of His – branches into the
Right and the Left bundle branch4. Purkinje fibers- fastest conduction
10
11
The Cardiovascular System
The Heart sounds1. S1- due to closure of the AV valves2. S2- due to the closure of the semi-
lunar valves3. S3- due to increased ventricular
filling4. S4- due to forceful atrial contraction
12
The Cardiovascular System
Heart rate• Normal range is 60-100 beats per
minute• Tachycardia is greater than 100 bpm• Bradycardia is less than 60 bpm• Sympathetic system INCREASES HR• Parasympathetic system (Vagus)
DECREASES HR

CVS Assessments
• History taking• Physical assessment• Psychosocial assessment• Laboratory assessment• Radiographic assessment• ECG• Hemodynamic monitoring
ASSESSING CARDIAC FUNCTION
• HEALTH ASSESSMENT: Health History
• PHYSICAL EXAMINATION
• DIAGNOSTIC TESTS– LABORATORY– INVASIVE TEST
• CARDIAC CATHETERIZATION
– Coronary angiography
– Coronary arteriography.
– NONINVASIVE TESTS • CXR• STRESS/EXERCISE
TEST• ECG
15
CARDIAC ASSESSMENT1. Health History• Obtain description of present illness
and the chief complaint• Chest pain, SOB, Edema,
palpitations, etc.• Assess risk factors• Personal habits and nutritional
history.• Activity-exercise• Sleep-rest.
16

History Taking• Personal particulars• Medical and surgical history• Family history and genetic risks• Diet history• Socioeconomic status• Risk factors – smoking, physical inactivity,
obesity, psychological factors• Present history of illness, sign & symptoms
– Chronic disease, pain, discomfort, dyspnea, fatigue,palpitations, weight gain, syncope, and extremity pain
CARDIAC ASSESSMENT
2. Physical examination• General appearance. • Vital signs- BP, PP, MAP• Inspection of the skin• Inspection of the thorax• Palpation of the point of
maximal impulse(PMI), pulses• Auscultation of the heart
sounds18

Physical Assessment
• General appearance• Skin & mucous membranes (colour,
temperature)• Extremities (clubbing, oedema, bruits, b/p,
pulse pressure)• Precordium (inspection, palpitation,
percussion & auscultation – heart sounds (paradoxical splitting, gallops & murmurs, pericardial friction rub).

3. Peripheral vascular system:
a. Inspection:
. Skin - colour.
. Extremities:
- edema.
- clubbing of fingers.
- varicosities.
- lesions.
. Neck
- large veins.

b. Palpation:
. Upper and lower extremities:
- temperature.
- pulses.
- edema.

24
Percussion
Unnecessary in the CVS examination (except lung bases)
Percuss and listen to the lung basesFor any signs of pleural effusion (RVF)
and pulmonary oedema (LVF)
25
Auscultation• Heart sound• 1st heart sound – closure of
tricuspid and mitral valve.• 2nd heart sound – closure of aortic
and • pulmonary valves.• 3rd and 4th heart sound – extra
heart sound.• Murmur – sounds occuring between
normal heart sound.• Pericardial friction rub – scratchy
sound between S1 and S2.26

Laboratory studies
Laboratory Test Rationale1. To assist in diagnosing MI2. To identify abnormalities3. To assess inflammation4. To determine baseline value5. To monitor serum level of medications6. To assess the effects of medications

Laboratory Assessment
• Serum Markers Troponin Creatine Kinase (CK)-MB
• Serum Lipids• Homocysteine• C-Reactive Protein• Blood Coagulation Tests
Prothombin Time & International Normalised Ratio (INR) Partial Thromboplastin Time (PTT)
• Arterial Blood Gases• Serum Electrolytes• Complete Blood Count

Radiographic Assessment
• Chest Radiography Size of heart, pulmonary congestion, position of heart
and catheters Preparation of patient
• Angiography Invasive diagnostic procedure when suspect arterial
obstruction, narrowing or aneurysm. A contrast media is used and fluoroscopy to see the flow of contract
Preparation of patient
• Cardiac Catheterization To study right, left heart and coronary arteries Preparation of patient

Electrocardiogram (ECG)
• Resting 12 lead or rythmn continous monitoring
• Ambulatory (Holter monitoring) 24 hrs ECG recording to detect dysrythmias
• Exercise ECG – stress test Assess CVS responds to increased workload Helps to determine functional capacity of the heart and
screens for asymptomatic coronary artery disease Preparation
• Echocardiography Ultrasound waves to assess cardiac structure and
mobility especially of valves

DIAGNOSTIC TESTS
ELECTROCARDIOGRAM (ECG)
• A non-invasive procedure that evaluates the electrical activity of the heart.
33
DIAGNOSTIC TESTSHolter Monitoring• A non-invasive test in which
the client wears a Holter monitor and an ECG tracing recorded continuously over a period of 24 hours
• Instruct the client to resume normal activities and maintain a diary of activities and any symptoms that may develop.
34
DIAGNOSTIC TESTSStress Test• A non-invasive test that studies
the heart during activity and detects and evaluates CAD
• Exercise test, pharmacologic test and emotional test
• Used to determine CAD, Chest pain causes, drug effects and dysrhythmias in exercise
35
DIAGNOSTIC TESTSECHOCARDIOGRAM• Non-invasive test
that studies the structural and functional changes of the heart with the use of ultrasound
• No special preparation is needed
36
DIAGNOSTIC TESTS
CARDIAC catheterization• Insertion of a catheter into the
heart and surrounding vessels• Determines the structure and
performance of the heart valves and surrounding vessels.
• Used to diagnose CAD, assess coronary atery patency and determine extent of atherosclerosis.
37
38
Hemodynamic monitoring
• An invasive monitoring system esp in ICU• Directly measures pressures in the heart and great
vessels.Measuring:
Vascular capacity Blood volume Pump effectiveness Tissue perfusion
• Right Atrial Pressure• Pulmonary Artery Pressure• Pulmonary Artery Wedge Pressure• Cardiac output – Thermodilution method
DIAGNOSTIC TESTS
CVP• The CVP is the
pressure within the Superior Vena Cava
• Reflects the pressure under which blood is returned to the SVC and right atrium
39
DIAGNOSTIC TESTS
CVP• Normal CVP is 0 to 8 mmHg/ 4-10
cm H2O• Elevated CVP indicates increase in
blood volume, excessive IVF or heart/renal failure
• Low CVP may indicated hypovolemia, hemorrhage and severe vasodilatation
