Label	Id	Description
Hearing Loss, Sudden	D003639	[Complete sensorineural hearing loss which develops suddenly over a period of hours or a few days., Sensorineural hearing loss which develops suddenly over a period of hours or a few days. It varies in severity from mild to total deafness. Sudden deafness can be due to head trauma, vascular diseases, infections, or can appear without obvious cause or warning.]
Hearing Loss, Unilateral	D046088	[Partial or complete hearing loss in one ear.]
Heart Aneurysm	D006322	[A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.]
Heart Arrest	D006323	[Cessation of heart beat or MYOCARDIAL CONTRACTION. If it is treated within a few minutes, heart arrest can be reversed in most cases to normal cardiac rhythm and effective circulation.]
Heart Block	D006327	[Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.]
Heart Defects, Congenital	D006330	[Developmental abnormalities involving structures of the heart. These defects are present at birth but may be discovered later in life.]
Heart Diseases	D006331	[Pathological conditions involving the HEART including its structural and functional abnormalities.]
Heart Failure	D006333	[Heart failure involving the RIGHT VENTRICLE., Heart failure accompanied by EDEMA, such as swelling of the legs and ankles and congestion in the lungs., Heart failure caused by dysfunction of the MYOCARDIUM, leading to defective cardiac emptying (contraction) or filling (relaxation)., A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION., Heart failure involving the LEFT VENTRICLE.]
Heart Failure, Diastolic	D054144	[Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.]
Heart Failure, Systolic	D054143	[Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.]
Heart Injuries	D006335	[General or unspecified injuries to the heart.]
Heart Murmurs	D006337	[Heart sounds caused by vibrations resulting from the flow of blood through the heart. Heart murmurs can be examined by HEART AUSCULTATION, and analyzed by their intensity (6 grades), duration, timing (systolic, diastolic, or continuous), location, transmission, and quality (musical, vibratory, blowing, etc).]
Heart Neoplasms	D006338	[Tumors in any part of the heart. They include primary cardiac tumors and metastatic tumors to the heart. Their interference with normal cardiac functions can cause a wide variety of symptoms including HEART FAILURE; CARDIAC ARRHYTHMIAS; or EMBOLISM.]
Heart Rupture	D006341	[Disease-related laceration or tearing of tissues of the heart, including the free-wall MYOCARDIUM; HEART SEPTUM; PAPILLARY MUSCLES; CHORDAE TENDINEAE; and any of the HEART VALVES. Pathological rupture usually results from myocardial infarction (HEART RUPTURE, POST-INFARCTION).]
Heart Rupture, Post-Infarction	D006342	[Laceration or tearing of cardiac tissues appearing after MYOCARDIAL INFARCTION.]
Heart Septal Defects	D006343	[Abnormalities in any part of the HEART SEPTUM resulting in abnormal communication between the left and the right chambers of the heart. The abnormal blood flow inside the heart may be caused by defects in the ATRIAL SEPTUM, the VENTRICULAR SEPTUM, or both.]
Heart Septal Defects, Atrial	D006344	[Developmental abnormalities in any portion of the ATRIAL SEPTUM resulting in abnormal communications between the two upper chambers of the heart. Classification of atrial septal defects is based on location of the communication and types of incomplete fusion of atrial septa with the ENDOCARDIAL CUSHIONS in the fetal heart. They include ostium primum, ostium secundum, sinus venosus, and coronary sinus defects.]
Heart Septal Defects, Ventricular	D006345	[Developmental abnormalities in any portion of the VENTRICULAR SEPTUM resulting in abnormal communications between the two lower chambers of the heart. Classification of ventricular septal defects is based on location of the communication, such as perimembranous, inlet, outlet (infundibular), central muscular, marginal muscular, or apical muscular defect.]
Heart Valve Diseases	D006349	[Pathological conditions involving any of the various HEART VALVES and the associated structures (PAPILLARY MUSCLES and CHORDAE TENDINEAE).]
Heart Valve Prolapse	D016127	[Downward displacement of any one of the HEART VALVES from its normal position. This usually results in failed valve closure.]
