Heart murmurs are abnormal sounds heard during a heartbeat cycle, typically due to turbulent blood flow within the heart or blood vessels. These murmurs can range from harmless to potentially indicative of underlying heart conditions. Murmurs may be detected during routine physical examinations or through diagnostic tests such as echocardiography….

Heart transplantation is a life-saving surgical procedure performed to replace a failing or diseased heart with a healthy donor heart. It is typically considered when other treatments for end-stage heart failure have been ineffective. The first successful human heart transplant was performed by Dr. Christiaan Barnard in 1967, marking a…

Heart rate, also known as pulse rate, refers to the number of times the heart beats per minute (bpm). It is a vital physiological parameter that provides valuable information about cardiovascular function and overall health. The heart rate is regulated by the autonomic nervous system, specifically the sympathetic and parasympathetic…

Heart valve disease occurs when one or more of the heart’s four valves—mitral, aortic, tricuspid, and pulmonary—do not function properly. These valves regulate blood flow through the heart, allowing it to pump efficiently. When a valve becomes damaged or diseased, it can disrupt blood flow, leading to symptoms such as…
