D016280 |
[The hemodynamic and electrophysiological action of the RIGHT ATRIUM.

Atrial Myosins
|
D024743 |
[Myosin type II isoforms specifically found in the atrial muscle of the heart.

|
Atrial Natriuretic Factor
|
D009320 |
[A potent circulating form of ANP that is a 28-amino acid peptide. It derives from the (99-126) amino acids of prohormone gamma-ANP, also known as ANP (1-126).
, A potent natriuretic and vasodilatory peptide or mixture of different-sized low molecular weight PEPTIDES derived from a common precursor and secreted mainly by the HEART ATRIUM. All these peptides share a sequence of about 20 AMINO ACIDS.
, The 126-amino acid C-terminal fragment of the ANP precursor, an approximately 150-amino acid polypeptide in a number of species. It is formed by the removal of the N-terminal signal sequence ANP (1-24). This prohormone contains various active ANF sequences.
, An antiparallel dimer of alpha-ANP with the chains linked by 7-23' and 7'-23 disulfide bonds.
, Polypeptides of about 150 amino acids that serve as precursors to prohormone of ATRIAL NATRIURETIC FACTOR, a 126-amino acid polypeptide or ANP (1-126).

Atrial Premature Complexes
|
D018880 |
[A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals may or may not conduct to the HEART VENTRICLES. Atrial premature complexes are characterized by premature P waves on ECG which are different in configuration from the P waves generated by the normal pacemaker complex in the SINOATRIAL NODE.

|
Atrial Pressure
|
D062185 |
[The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).

|
Atrial Remodeling
|
D064752 |
[Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.
] |
|
Atrial Septum
|
D054087 |
[The thin membrane-like muscular structure separating the right and the left upper chambers (HEART ATRIA) of a heart.
] |
|
Atrioventricular Block
|
D054537 |
[Impaired impulse conduction from HEART ATRIA to HEART VENTRICLES. AV block can mean delayed or completely blocked impulse conduction.
] |
|
Atrioventricular Node
|
D001283 |
[A small nodular mass of specialized muscle fibers located in the interatrial septum near the opening of the coronary sinus. It gives rise to the atrioventricular bundle of the conduction system of the heart.

Atriplex
|
D027466 |
[A plant genus in the CHENOPODIACEAE family.
] |
|
Atropa
|
D032282 |
[A plant genus of the family SOLANACEAE which contain SOLANACEOUS ALKALOIDS including ATROPINE which is named after this genus.
] |
|
Atropa belladonna
|
D001532 |
[A plant species of the genus ATROPA, family SOLANACEAE that contains ATROPINE; SCOPOLAMINE; BELLADONNA ALKALOIDS and other SOLANACEOUS ALKALOIDS. Some species in this genus are called deadly nightshade which is also a common name for SOLANUM.

|
Atrophic Vaginitis
|
D059268 |
[Inflammation of the vagina due to thinning of the vaginal wall and decreased lubrication associated with reduced estrogen levels at MENOPAUSE.
] |
|
Atrophy
|
D001284 |
[Decrease in the size of a cell, tissue, organ, or multiple organs, associated with a variety of pathological conditions such as abnormal cellular changes, ischemia, malnutrition, or hormonal changes.
] |
|
Atropine
|
D001285 |
[An alkaloid, originally from Atropa belladonna, but found in other plants, mainly SOLANACEAE. Hyoscyamine is the 3(S)-endo isomer of atropine.
] |
|
Atropine Derivatives
|
D001286 |
[Analogs and derivatives of atropine.

|
Attachment Sites, Microbiological
|
D001287 |
[Specific loci on both the bacterial DNA (attB) and the phage DNA (attP) which delineate the sites where recombination takes place between them, as the phage DNA becomes integrated (inserted) into the BACTERIAL DNA during LYSOGENY.

|
Attention
|
D001288 |
[Focusing on certain aspects of current experience to the exclusion of others. It is the act of heeding or taking notice or concentrating.
] |
|
Attention Deficit Disorder with Hyperactivity
|
D001289 |
[A behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood. (From DSM-V)

D019958 |
[Includes two similar disorders: oppositional defiant disorder and CONDUCT DISORDERS. Symptoms occurring in children with these disorders include: defiance of authority figures, angry outbursts, and other antisocial behaviors.
