Myxoma (Heart Tumor), Definition, Treatment and Surgery

Definition of Myxoma (Heart Tumor), Treatment and Surgery Myxoma is a nonmalignant tumor that grows in the heart, nearly always in one of the atria and most commonly in the left atrium. Myxoma arises from the endocardium and may be either firm or soft in consistency. The tumor can block the flow of blood through the atrium, […]

Chronic Venous Insufficiency – Definition, Symptoms and Treatment

Definition of Chronic Venous Insufficiency Venous insufficiency is a chronic condition in which the veins cannot adequately return blood to the heart, usually as a consequence of defective valves that allow blood to leak back and pool in the veins. Some people do not have valves in their veins, a circumstance that is a congenital anomaly. Venous insufficiency primarily […]

Palpitations – Definition and Causes

Definition of Palpitations Palpitations is perception that the heart is racing, pounding, or skipping beats. Palpitations are may represent signs of underlying cardiovascular conditions such as arrhythmia though frequently signal high stress, anxiety, or excessive consumption of stimulants such as caffeine or nicotine (via cigarette smoking). When palpitations do suggest arrhythmia, they tend to occur along with […]

Ventricular Fibrillation – Treatment

Definition of Ventricular Fibrillation Ventricular fibrillation – Rapid, irregular, ineffective contractions of the heart’s ventricles – quickly becomes fatal without treatment. The heart cannot pump blood to the lungs or to the body when it is in ventricular fibrillation. Ventricular fibrillation is a life-threatening event that requires emergency medical treatment. Treatment The electrocardiogram (ecg) provides a definitive diagnosis. Treatment may consist […]

Endocarditis – Symptoms, Causes and Treatment

Definition of Endocarditis Endocarditis is inflammation of the endocardium, the lining of the heart. Viral or bacterial infection can cause endocarditis; either is potentially life threatening, though bacterial infection is considerably more common. Bacterial endocarditis is a particular risk for people who have certain forms of cardiovascular disease (cvd) and may follow bacterial infection in other parts of the body. Pathogenic (infection-causing) bacteria may also […]

Paroxysmal Atrial Tachycardia (PAT) – Symptoms and Treatment

Definition of Paroxysmal Atrial Tachycardia An arrhythmia disorder, also called paroxysmal supraventricular tachycardia (PSVT), in which the atria have episodes of rapid, regular contractions. “Paroxysmal” means the symptoms start and stop abruptly, without apparent cause. During a PAT episode, the heart rate may reach 140 beats per minute. The atrial contractions of PAT originate in the atrium above the atrioventricular […]

Wolff-Parkinson-White Syndrome

Definition of Wolff-Parkinson-White Syndrome Wolff-Parkinson-White syndrome – An inherited arrhythmia disorder in which an extra conduction pathway, called an accessory pathway, exists between the heart’s atria and ventricles. The accessory pathway allows the heart’s electrical pacing impulse to bypass the normal conductive route, reaching the ventricles before the atria have completed their contraction cycle. While many people […]

Heart Attack – Symptoms, Treatment and Definition

Definition of Heart Attack Heart attack is the interruption of cardiovascular function. The most common cause of heart attack is myocardial infarction, a blockage of the coronary arteries, usually with a blood clot, that disrupts the flow of blood to the heart (myocardium). Other causes of heart attack include arrhythmia, systemic hypoxia (such as may occur with drowning or carbon monoxide poisoning), […]

Pericarditis – Symptoms and Treatment

Definition of Pericarditis Pericarditis is inflammation of the pericardium, the membranous sac that surrounds and protects the heart. Pericarditis can be acute (comes on suddenly) or chronic (intermittent symptoms over a period of time), the result of an infection or an autoimmune disorder such as rheumatoid arthritis. Infections are usually viral, with the coxsackie virus and echovirus the most common culprits, though viral pericarditis […]
