Cardiac Evaluation

Cardiac evaluarion consists of patient history, physical examination (which consists of observation, palpation, BP measurement, and heart sound auscultation), laboratory rests, and diagnostic

procedures.

Patiellt History

In addition to the general charr review presented in Appendix I-A,

pertinent information about patients with cardiac dysfunction that

should be obtained before physical examination includes the

following'· 10-12:

• Presence of chest pain (see Appendix X for an expanded

description of characteristics and etiology of chest pain)

1. Location, radiation

2. Character and quality (crushing, burning, numbing, hot)

and frequency

3. Angina equivalents (what the patient feels as angina, e.g.,

jaw pain, shortness of breath, dizziness, lightheadedness, diaphoresis, burping, nausea, or any combination of these)

4. Aggravating and alleviating factors

5. Precipitating factors

• Medical treatment sought and its outcome

• Presence of palpitations

• Presence of cardiac risk factors (Table 1-4)

• Family history of cardiac disease

o History of dizziness or syncope

o Previous myocardial infarction (MI), cardiac studies, or procedures

Clinical Tip

• When discussing angina with a patient, use the patient'S

terminology. If the patient describes the angina as "crushing" pain, ask the patient if he or she experiences the crushing feeling during treatment as opposed to asking the

patient if he or she has chest pain.

o The common medical record abbreviation for chest

pain is CPo

Physical Exam;1Iatio1l

Observation

Key components of the observation portion of the physical examination include the following··7:

1 .

Facial color, skin color and rone, or the presence of diaphoresis

2.

Obvious signs of edema in the extremities

3.

Respiratoty rate

4.

Signs of trauma (e.g., paddle burns or ecchymosis from cardiopulmonary resuscitation)

5.

Presence of jugular venous distention, which results from

the backup of Auid into the venous system from right-sided CHF

(Figure 1-5)

a. Make sure the patient is in a semirecumbent position (45

degrees).

b. Have the patient turn his or her head away from the side

being evaluated.

c. Observe pulsations in the internal jugular neck region.

Pulsations are normally seen 3-5 em above the sternum. Pul-

Palpation

Palpation is the second component of the physical examination and is

used to evaluate and identify the following:


Pulses for circulation qua�ty, HR, and rhythm (Table 1-5, Figure 1-6)


Exttemities for pitting edema bilaterally (Table 1-6)
