The c wave corresponds to right ventricular contraction causing the closed tricuspid valve to bulge towards the right atrium during RV isovolumetric contraction. The x ' descent follows the 'c' wave and occurs as a result of the right ventricle pulling the tricuspid valve downward during ventricular systole (ventricular ejection/atrial relaxation).
"pounding in the neck" or neck pulsations, often due to cannon A waves in the jugular vein, pulsations that occur when the right atrium contracts against a closed tricuspid valve. [3] Palpitation associated with chest pain suggests coronary artery disease, or if the chest pain is relieved by leaning forward, pericardial disease is suspected.
Sexual headache is a type of headache that occurs in the skull and neck during sexual activity, including masturbation or orgasm.These headaches are usually benign, but occasionally are caused by intracranial hemorrhage and cerebral infarction, especially if the pain is sudden and severe. [1]
Migraine causes a "severe throbbing or pounding headache with light or sound sensitivity and sometimes nausea," noted Dr. Timothy A. Collins, chief of the Division of Headache and Pain at Duke ...
Blood clots are a medical emergency in their own right—and can lead to heart attack and stroke—so if you notice these changes, seek treatment right away, she urges. Jaw or neck pain with exertion
In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...
The parietal branch of the superficial temporal artery (posterior temporal) is a small artery in the head.It is larger than the frontal branch and curves upward and backward on the side of the head, lying superficial to the temporal fascia; it joins with its fellow of the opposite side, and with the posterior auricular and occipital arteries.
The left and right external jugular veins drain into the subclavian veins. The internal jugular veins join with the subclavian veins more medially to form the brachiocephalic veins. Finally, the left and right brachiocephalic veins join to form the superior vena cava, which delivers deoxygenated blood to the right atrium of the heart. [2]
