With cardiac tamponade, jugular veins are distended and typically show a prominent x descent and an absent y descent as opposed to patients with constrictive pericarditis (prominent x and y descent); see Beck's triad. [1] Other possible causes of Kussmaul's sign include: [2] [citation needed] Right ventricular infarction - low ventricular ...
Laboratory investigations reveal signs of a bacterial infection with elevated C-reactive protein, erythrocyte sedimentation rate and white blood cells (notably neutrophils). Platelet count can be low or high. Liver and kidney function tests are often abnormal. [citation needed] Thrombosis of the internal jugular vein can be displayed with ...
The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease. Classically three upward deflections and two downward deflections have ...
The jugular vein is prominent in heart failure. When the patient is sitting or in a semirecumbent position, the height of the jugular veins and their pulsations provides an estimate of the central venous pressure and gives important information about whether the heart is keeping up with the demands on it or is failing.

Cannon A wave. Cannon A waves, or cannon atrial waves, are waves seen occasionally in the jugular vein of humans with certain cardiac arrhythmias.When the atria and ventricles happen to contract simultaneously, the right atrium contracts against a closed tricuspid valve, resulting in back pressure into the venous system that can be seen in the jugular venous pulse as a high-amplitude "cannon ...
Loose Anagen Syndrome can commonly be misdiagnosed for other skin and hair disorders such as short anagen syndrome, alopecia areata, telogen effluvium, trichotillomania and toxic ingestion. Similar symptoms and signs appear in these conditions, however there are different aspects that distinguish each one from another.
It is differentiated from secondary causes of upper extremity thrombosis caused by intravascular catheters. [4] Paget–Schroetter syndrome was described once for a viola player who suddenly increased practice time 10-fold, creating enough repetitive pressure against the brachiocephalic and external jugular veins to cause thrombosis.
Trichorrhexis nodosa is a defect in the hair shaft characterized by thickening or weak points (nodes) that cause the hair to break off easily. [ 2 ] [ 3 ] : 636 This group of conditions contributes to the appearance of hair loss , lack of growth, and damaged-looking hair.
