Cardiac tamponade: Cardiac tamponade occurs due to fluid accumulation in the pericardial space and typically presents with chest pain often accompanied by symptoms like dyspnea, hypotension, and pulsus paradoxus. Clinical signs include Beck's triad—hypotension, jugular venous distension, and muffled heart sounds. [15]
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
SLE may cause pericarditis (inflammation of the outer lining surrounding the heart), myocarditis (inflammation of the heart muscle), or endocarditis (inflammation of the inner lining of the heart). The endocarditis of SLE is non-infectious, and is also called Libman–Sacks endocarditis.
In a normal heart, the heart rate is the rate at which the sinoatrial node depolarizes since it is the source of depolarization of the heart. Heart rate, like other vital signs such as blood pressure and respiratory rate, change with age. In adults, a normal heart rate is between 60 and 100 bpm (normocardic), whereas it is higher in children. [57]
People with RA are more prone to atherosclerosis, and risk of myocardial infarction (heart attack) and stroke is markedly increased. [28] [29] [30] Other possible complications that may arise include: pericarditis, endocarditis, left ventricular failure, valvulitis and fibrosis. [31]
The avian circulatory system is driven by a four-chambered, myogenic heart contained in a fibrous pericardial sac. This pericardial sac is filled with a serous fluid for lubrication. [ 38 ] The heart itself is divided into a right and left half, each with an atrium and ventricle .
Surgery [a] is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissues (body fat, glands, scars ...
