A plant genus of the family ASTERACEAE. Members contain ATRACTYLOSIDE which inhibits ADENINE NUCLEOTIDE TRANSLOCASE.
A plant genus of the family ASTERACEAE. Members contain hinesol and atractylon. Atractylodes rhizome is Byaku-jutsu. A. lancea rhizome is So-jutsu.
A glycoside of a kaurene type diterpene that is found in some plants including Atractylis gummifera (ATRACTYLIS); COFFEE; XANTHIUM, and CALLILEPIS. Toxicity is due to inhibition of ADENINE NUCLEOTIDE TRANSLOCASE.
A non-depolarizing neuromuscular blocking agent with short duration of action. Its lack of significant cardiovascular effects and its lack of dependence on good kidney function for elimination provide clinical advantage over alternate non-depolarizing neuromuscular blocking agents.
for the treatment of atopic dermatitis
A selective triazine herbicide. Inhalation hazard is low and there are no apparent skin manifestations or other toxicity in humans. Acutely poisoned sheep and cattle may show muscular spasms, fasciculations, stiff gait, increased respiratory rates, adrenal degeneration, and congestion of the lungs, liver, and kidneys. (From The Merck Index, 11th ed)
Ear-shaped appendage of either atrium of the heart. (Dorland, 28th ed)
Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
mutation in KCNQ1
Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
The hemodynamic and electrophysiological action of the HEART ATRIA.
The hemodynamic and electrophysiological action of the LEFT ATRIUM.
The hemodynamic and electrophysiological action of the RIGHT ATRIUM.
Myosin type II isoforms specifically found in the atrial muscle of the heart.
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.
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.
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).
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.
aka ASD5
TLL1 mutations
A heterogeneous group of atrial heart septal defects (ASD) that occurs both sporadically and in families (OMIM: 108800). Conduction defects or non-cardiac abnormalities may or may not be present. In familial cases, genes have been mapped and mutations identified for several types, including a mutation in the GATA4 gene for ASD2 (OMIM: 607941).
The thin membrane-like muscular structure separating the right and the left upper chambers (HEART ATRIA) of a heart.
