Right heart failure
Right heart failure refers to a clinical syndrome caused by right ventricular systolic and/or diastolic dysfunction due to any cause, which is insufficient to provide the cardiac output required by the body. It is mainly characterized by systemic symptoms of systemic congestion, such as abdominal distension, abdominal pain, poor appetite, nausea, vomiting, decreased urine output, dyspnea, and edema.
View detailsPediatric ventricular tachycardia
Pediatric ventricular tachycardia refers to a rapid arrhythmia (heart rate greater than 150 beats per minute during an episode) that originates below the His bundle (a structure in the heart) and its branches. It is a serious arrhythmia that can lead to sudden cardiac death. Common symptoms include increased heart rate, as well as dizziness, palpitations, and chest tightness.

Pediatric paroxysmal supraventricular tachycardia (PSVT) refers to a specific type of arrhythmia that occurs in children. The heart is divided into atria and ventricles. PSVT is a tachycardia (heart rate greater than 150 beats/min) that originates in the atria or atrioventricular junctional area. The incidence of this condition is approximately 1/25,000. It is more common in infants, especially male infants under 4 months of age.
Cardiac edema
Cardiac edema is a type of body edema caused by cardiac dysfunction and is one of the common manifestations of heart disease. Common diseases that cause cardiac edema include congestive heart failure, valvular heart disease, acute or chronic pericarditis, constrictive pericarditis, restrictive cardiomyopathy, acute or chronic pulmonary vascular disease, and cor pulmonale. Edema generally starts in the dependent parts of the body and gradually develops into generalized edema. Pitting edema of the lower extremities usually appears first, with the ankles being the most prominent.

Cardiogenic syncope refers to syncope caused by heart disease, often serving as a precursor or component of sudden death. It is characterized by poor self-limitation and difficulty in spontaneous recovery. Cardiogenic syncope can lead to Adams-Stokes syndrome (i.e., cardiogenic cerebral ischemia syndrome) and, in severe cases, can result in patient death.
View detailsCardiac arrest
Cardiac arrest refers to the sudden cessation of the heart's pumping function due to various causes, followed by coma, absence of pulse, and cessation of breathing. Cardiac arrest can occur in anyone, but individuals aged 35-45 with pre-existing structural heart problems are at high risk, and it is more common in men than in women.
View detailsConstrictive pericarditis
Constrictive pericarditis results from pericardial scarring and the subsequent loss of normal elasticity of the pericardial sac. It manifests as restricted cardiac contraction and relaxation, impaired heart function, and systemic circulatory disturbances, representing a chronic disease.
View detailsChylous blood
In patients with severe hyperlipidemia, the blood may contain a large amount of chylomicrons, appearing as a white, turbid substance, clinically known as "lipemic blood." Lipemic blood is a clinical manifestation of severely elevated triglycerides in the blood. Patients often experience recurrent abdominal pain, anemia, fatigue, difficulty concentrating, poor memory, and blurred vision.
View detailsPapillary muscle dysfunction
Papillary muscle dysfunction refers to a series of clinical syndromes, such as mitral regurgitation, caused by the inability of the mitral valve to close properly due to impaired contraction of the papillary muscles (the fine connective tissue cords that connect the papillary muscles to the atrioventricular valves) due to ischemia, necrosis, fibrosis, etc. It is common in patients with coronary heart disease, acute myocardial ischemia (angina pectoris, myocardial infarction), and chronic myocardial interstitial fibrosis.
