The patient's pulse demonstrates ______ deficit, where the number of heart sounds exceeds the number of peripheral pulses felt.

해설
Pulse deficit occurs when there is a discrepancy between the number of heart sounds heard and peripheral pulses palpated. This finding is common in atrial fibrillation, where some contractions may be too weak to generate a palpable peripheral pulse.

임상 시나리오

1. Pulse deficit definition: Difference between apical heart rate and peripheral pulse rate

2. Common causes:
- Atrial fibrillation
- Premature contractions
- Weak ventricular contractions
- Heart blocks

3. Clinical assessment:
- Compare apical pulse with radial pulse
- Count for full minute
- Normal finding: Equal rates
- Deficit: Apical rate > Radial rate

4. Associated conditions:
- Cardiac arrhythmias
- Heart failure
- Valvular heart disease
- Cardiomyopathy

5. Key points:
- Diagnostic value in cardiac assessment
- Indicates ineffective cardiac output
- Requires immediate medical attention
- Important vital sign measurement

6. Documentation:
- Record both apical and radial rates
- Calculate deficit
- Note rhythm irregularities
- Monitor trends
