Study Notes

Cardiac Structures and Imaging

Major cardiac structures are visualized through the chest wall.
Normal chest radiographs reveal the cardiac chambers and great vessels:
- Aorta (AO)
- Left Atrium (LA)
- Left Ventricle (LV)
- Pulmonary Artery (PA)
- Right Atrium (RA)
- Right Ventricle (RV)
- Superior Vena Cava (SVC)

Cardiac Anatomy and Circulation

Key cardiac chambers:
- Right Atrium (RA)
- Left Atrium (LA)
- Right Ventricle (RV)
- Left Ventricle (LV)
Understanding blood flow direction is essential during the cardiac cycle.

Cardiac Conduction System

The cardiac conduction system orchestrates electrical impulses that regulate heartbeats.

Jugular Venous Pressure (JVP)

JVP height remains constant in different patient positions, sometimes detectable only when recumbent or upright.
Measurement techniques include using a horizontal card and a vertical ruler.

Pulse Examination Techniques

Palpating for the carotid pulse involves utilizing index and middle fingers for accuracy.
The apical impulse is best palpated in the left lateral decubitus position.
The point of maximal impulse (PMI) is described relative to the midsternal or midclavicular lines.

Auscultation and Heart Sounds

Identifying auscultatory areas on the chest wall is critical for cardiac examination.
Understanding radiation of heart sounds and murmurs aids in diagnosing heart conditions.
Specific positions enhance auscultation for particular conditions:
- Mitral stenosis is best assessed in the left lateral decubitus position.
- Aortic regurgitation is evaluated with the patient leaning forward.
