QuestionChoice
Cardiac tamponade is associated with Beck's triad: hypotension, muffled heart sounds and a raised JVP. It occurs when there is an accumulation of fluid or blood in the pericardial cavity. This compresses the heart, preventing diastolic filling and thus reducing cardiac output. Causes of symmetrically reduced chest expansion include pulmonary fibrosis, whereas pneumothorax, pneumonia and pleural effusions all cause asymmetrical reduced chest expansion.

QuestionChoice
Cardiac tamponade is associated with Beck's triad: hypotension, muffled heart sounds and a raised JVP. It occurs when there is an accumulation of fluid or blood in the pericardial cavity. This compresses the heart, preventing diastolic filling and thus reducing cardiac output. No observable JVP is a normal examination finding.

c
No observable JVP
QuestionChoice
This is the correct answer. Cardiac tamponade occurs when there is an accumulation of fluid or blood in the pericardial cavity. This compresses the heart, preventing diastolic filling and thus reducing cardiac output. Cardiac tamponade is associated with Beck's triad: hypotension, muffled heart sounds and a raised JVP.

Cardiac tamponade is associated with Beck's triad: hypotension, muffled heart sounds and a raised JVP. It occurs when there is an accumulation of fluid or blood in the pericardial cavity. This compresses the heart, preventing diastolic filling and thus reducing cardiac output. A deviated trachea can be seen in many conditions, most notably in tension pneumothoraces.

A 19-year-old female is brought to the Emergency Department by ambulance after suffering a stab wound to the chest. She has lost a significant amount of blood and is tachycardic and dyspnoeic. The clinician treating her suspects cardiac tamponade and an echocardiogram confirms the diagnosis.

Which of the following signs is the clinician most likely to see in this patient?
a
