Articular surfaces of the wrist.  

Ischemia of the anterior carotid arteries that lasts for 24 hours or less, causing neurological deficits in speech, vision, motor tracts, and balance.  

Condition where stimulation of a hyperactive carotid sinus causes a severe drop in blood pressure due to vasodilation and bradycardia resulting in syncope. Carotid sinus hypersensitivity is a condition primarily observed in older individuals, characterized by an excessive sensitivity of the carotid sinus. The carotid sinus is a structure located within the common carotid artery…

Systolic murmur detectable in the neck but not in the aortic area. A carotid bruit refers to an abnormal sound detected in a carotid artery, one of the major arteries that supplies the neck and head. This noise arises from turbulent blood flow within the artery. By placing a stethoscope on the side of a…

Rupture of the wall of the myocardium.  

Parasympathetic nervous system area in the brain that monitors the heart rate and strength of contraction.  

Sympathetic nerve center that increases the heart rate and strength of contraction.  

The two lower heart chambers directly below the atrium, called right and left ventricles, respectively.  

Transient and sudden loss of consciousness due to inadequate cardiac output associated with bradycardia, tachycardia, or myocardial infarct. Syncope of cardiac origin as in Stokes-Adams syndrome, aortic stenosis, tachycardia, bradycardia, or myocardial infarction.  

Diagnostic study of the heart using an injection of a radioisotope and subsequent uptake by the myocardium, followed by imagery by a gamma camera of the heart beating; measures the volume of blood pumped by each ventricle.
