“…As pericardial pressure increases, there is also an exaggeration of the normal respiratory variation in the pressures across the tricuspid and mitral valves. With inspiration, there is normally a decrease in the inflow velocity across the MV (less than 10%), as inspiration causes increased negative intrathoracic pressure, which increases venous flow to the RV/RA and decreases flow to the LV/LA as a result of interventricular dependence . The change in transvalvular flow velocities is described as the flow velocity paradoxus.…”

The presentation of cardiac tamponade is a spectrum from occult to extreme. The clinical history, physical exam, electrocardiogram, and radiographic findings of tamponade have poor sensitivities and even worse specificities. We use a clinical scenario to demonstrate how point-of-care cardiac ultrasound can diagnose impending cardiac tamponade in a clinically stable patient. The ultrasound finding we recommend is the flow velocity paradoxus, in which respiratory variation causes significant changes in transvalvular inflow velocities, which are exaggerated when tamponade is present. The management of a pericardial effusion depends on its physiologic effect, and point-of-care ultrasound directly measures that effect and expedites patient care.

“…hypotension ( systolic pressure <90 mmHg), poorly detectable pulse, jugular venous distension, muffled heart sounds. Paradoxic pulse is observed (reduced amplitudes of inspiratory arterial pressure ≥ 20 mmHg) [12]. However, lack of these symptoms does not exclude possible development of cardiac tamponade.…”

Case report. A 58-year-old woman was admitted to the Department of Internal Diseases due to resting dyspnoea, tachycardia and malaise. Her chest X-ray revealed inflammatory lesions, and empiric antibiotic therapy was initiated. Chest CT was then performed which showed lung tumours. During hospitalization, the patient suddenly developed cardiogenic shock induced by pericardial tamponade. The fluid from pericardium was subsequently collected. An histopathological examination of the fluid showed the presence of atypical cells. The patient then underwent bronchoscopy, the biopsy material of which revealed bronchial adenocarcinoma.
