Overview
Physical examination may vary depending on the type of cardiac tamponade. Physical examination may show the classic Beck's triad (hypotension, muffled heart sound, and elevated jugular venous distension), tachycardia, pulsus paradoxus, and pericardial rub depending on the type, and severity of tamponade. Initial diagnosis can be challenging, as there are a number of differential diagnoses, including Tension pneumothorax [1], and acute heart failure.
Physical Examination
Vital signs & General physical examination
- Sinus tachycardia
- Beck's triad[2]
- Hypotension occurs because of decreased stroke volume
- jugular venous distension due to impaired venous return to the heart, and
- muffled heart sounds due to fluid inside the pericardium [3]
- Pulsus paradoxsus (a drop of > 10 mmHg in arterial blood pressure on inspiration) [4].
- Altered sensorium (decreasing Glasgow coma scale)
- Diminished peripheral pulses
- Peripheral edema
Cardiovascular
Auscultation
- Diminished S1 and S2
- Pericardial rub
- As Ventricular volume shrinks disproportionately, there may be psuedoprolapse/true prolapse of mitral and/or tricuspid valvular structures that result in clicks.
Pulsus paradoxsus
