Kawasaki Disease – In Children – Symptoms and Treatment

Definition of Kawasaki Disease Kawasaki disease is an acute condition affecting children that can weaken the coronary arteries and other cardiovascular structures, resulting in heart attack, aneurysm, or permanent damage. Kawasaki disease, also called mucocutaneous lymph node syndrome, comes on suddenly with rash, fever, conjunctivitis, and swollen lymph nodes (lymphadenopathy). Symptoms The characteristic symptom that raises suspicion the condition is more […]

Tamponade, Cardiac – Definition

Definition of Tamponade Tamponade is a life-threatening compression of the heart that prevents it from expanding to fill with blood. Cardiac tamponade is most often a complication of pericarditis and develops when fluid rapidly accumulates within the layers of the percardium. The pericardium’s fibrous outer layer does not readily expand, which forces the fluid to press inward against the heart. Without […]

Cardiovascular Disease (CVD) – Definition, Causes and Risk Factors

Definition of Cardiovascular Disease (CVD) Cardiovascular Disease (CVD) is the collective term for the numerous health conditions of the heart and blood vessels. Cardiovascular disease (CVD) is the leading cause of death and disability in the United States and in many other developed countries. More than 70 million Americans live with CVD; 10 million of them have sufficient […]

Long QT Syndrome (LQTS) – Symptoms and Treatment

Definition of Long QT Syndrome (LQTS) An arrhythmia disorder in which an electrical conduction defect in the heart results in delayed repolarization of myocardial cells. Repolarization is the process by which myocardial cells restore themselves to receive another electrical impulse. With LQTS, the myocardial cells hold a positive charge much longer than normal, preventing the heart from […]

Tetralogy of Fallot

Definition of Tetralogy of Fallot Disorder Tetralogy of Fallot (TOF) is one of the congenital heart disorders. It is characterized by four inborn abnormalities. It is named after the French physician Étienne-Louis Arthur Fallot. It is the most common cyanotic heart defect, and the most common cause of blue baby syndrome. The four abnormalities are: […]

Carotid Stenosis – Definition and Treatment

Definition of Carotid Stenosis Carotid Stenosis is narrowing of the carotid artery in the neck due to atherosclerosis. Often carotid stenosis shows no symptoms until it results in a stroke. The doctor may detect carotid stenosis during routine physical examination when listening to the carotid arteries with a stethoscope, which reveals the characteristic murmur sound, carotid bruit, that indicates the stenosis. […]

Microinfarction

Definition of Microinfarction Tiny arterial occlusions that briefly block the flow of blood to the brain, causing transient ischemic attacks (TIAs), or to the heart. What microinfarction lacks in initial effect it makes up through frequency. It may also affect other key organs such as the kidneys and liver. Conditions that can result in microinfarction […]

Torsade de Pointes – Definition and Treatment

Definition of Torsade de Pointes A life-threatening ventricular tachycardia (rapid contractions of the ventricles) that is the most serious complication of the arrhythmia disorder long qt syndrome (lqts). Torsade de pointes is a distinctive pattern of QRS complex electrical activity, QRS being the points on the electrocardiogram (ecg) that identify ventricular contraction. The term “torsade de pointes” means “twisting around […]

Congenital Heart Disease

Definition of Congenital Heart Disease Congenital Heart Disease – heart conditions, including structural anomalies of the heart, that are present from birth. Some forms of congenital heart disease are mild to moderate and require minimal or one-time intervention to correct. Congenital heart malformations are among the most common birth defects in the United States. Though still the […]

Myocardial Infarction – Definition, Symptoms, Treatment and ECG

Definition of Myocardial Infarction Death of heart tissue. The most common cause of myocardial infarction is occlusion of the coronary arteries such as occurs as a consequence of coronary artery disease (cad) or less frequently of coronary artery spasm. Myocardial infarction is the clinical term doctors use for heart attack. the myocardium has very high oxygen needs, as oxygen is the only […]
