A medical triad is a group of three signs or symptoms, the result of injury to three organs, which characterise a specific medical condition. The appearance of all three signs conjoined together in another patient, points to that the patient has the same medical condition, or diagnosis.
Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, a medical emergency when excessive fluid accumulates in the pericardial sac around the heart and impairs its ability to pump blood. The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds. [1]
Charcot's cholangitis triad is the combination of jaundice; fever, usually with rigors; and right upper quadrant abdominal pain. It occurs as a result of ascending cholangitis (an infection of the bile duct in the liver). When the presentation also includes low blood pressure and mental status changes, it is known as Reynolds' pentad. [1]
Whipple's triad is a collection of three signs (called Whipple's criteria) that suggests that a patient's symptoms result from hypoglycaemia that may indicate insulinoma.The essential conditions are symptoms of hypoglycaemia, low blood plasma glucose concentration, and relief of symptoms when plasma glucose concentration is increased.
The classic triad of symptoms found in Wernicke encephalopathy is: [11] ophthalmoplegia (later expanded to other eye movement disorders, most commonly affecting the lateral rectus muscle. [11] Lateral nystagmus is most commonly seen although lateral rectus palsy, usually bilateral, may be seen). ataxia (later expanded to imbalance or any ...
The three classic signs, known as Beck's triad, are low blood pressure, jugular-venous distension, and muffled heart sounds. [24] Other signs may include pulsus paradoxus (a drop of at least 10 mmHg in arterial blood pressure with inspiration), [12] and ST segment changes on the electrocardiogram, [24] which may also show low voltage QRS ...
A classic finding of cardiac tamponade is Beck's triad. The triad includes hypotension, jugular vein distension, and muffled heart sounds. Kussmaul's sign and pulsus paradoxus may also be seen. [10] Low-voltage QRS complexes and electrical alternans are signs on EKG. However, EKG may not show these findings and most often shows tachycardia. [11]
Reynolds' pentad is a collection of signs and symptoms consistent with obstructive ascending cholangitis, a serious infection of the biliary tract.It is a combination of Charcot's triad (right upper quadrant pain, jaundice, and fever) with shock (low blood pressure, tachycardia) and an altered mental status.
