Beck triad
Updates to Article Attributes
Beck triad is a collection of three clinical signs associated with pericardial tamponade which is due to an excessive accumulation of fluid within the pericardial sac. The three signs are:
- low blood pressure (weak pulse or narrow pulse pressure)
- muffled heart sounds
- raised jugular venous pressure
Pathology
The accumulation of fluid in the pericardial sac, particularly if it happens quickly, can result in marked increased pressure outside the heart; this subsequently reduces the ability of the ventricles to accommodate enough blood volume at the end of diastole. Based on Frank Starling's law, a decreased end diastolic-diastolic volume means weaker stroke volume and hence lower systolic blood pressure. Also, increased outside pressure reduces the end systolic-systolic filling capacity of the atria, hence a rapid increase and higher pressure in atria leads to an increased pressure in, and distension of, the jugular veins even when the patient is in an upright position. Excess fluid around the heart deadens the cardiac sounds.
History and etymology
It was first described in 1935 by an American cardiothoracic surgeon Dr. Calude Beck.
Difference between becks triad and Kussmaul’s sign
Becks triad: Becks triad referred to distended neck veins, muffled heart sounds, and hypotension. Pulsus Paradoxux: decrease in systolic pressure with spontaneous inspiration. it is classically associated with cardiac tamponade.
Kussmaul’s sign: Kussmaul sign is the paradoxical elevation of Central venous pressure during inspiration. Kussmaul sign is classically associated with constrictive pericarditis. Still, it occurs in only the minority of patients with constriction and is found in other conditions, such as myocardial infarction (MI), pulmonary embolism, and right ventricle infraction.
