Which diagnostic test for Cardiac Tamponade shows right ventricle collapse during early diastole?
EKG
Echocardiogram
CT Scan
PocUS
The correct answer is: Echocardiogram
The echocardiogram is the most effective diagnostic tool for assessing cardiac tamponade, particularly for visualizing the collapse of the right ventricle during early diastole. This phenomenon occurs due to the increased intrapericardial pressure that restricts the heart's ability to fill properly. In an echocardiogram, real-time imaging techniques, like 2D and Doppler ultrasound, provide valuable insights into the heart's structure and function. Clinicians can observe not only the collapse of the right ventricle but also evaluate other signs indicative of cardiac tamponade, such as pericardial effusion, diastolic filling patterns, and interventricular septal motion. Such detailed visual assessment is crucial in diagnosing and managing this condition effectively. Other options, while relevant in different contexts, do not provide the same level of detail or the specific dynamic data necessary to observe right ventricle collapse. EKG can indicate electrical abnormalities associated with cardiac tamponade but lacks the ability to visually depict structural changes. A CT scan is useful for identifying pericardial effusion but typically does not offer real-time assessment of cardiac function during the cardiac cycle. Point-of-care ultrasound (PocUS) can show some signs of tampon
