Electrical signals initiated in the sa node are transmitted to the atria and the ventricles to stimulate heart muscle contractions heartbeats. Sinus tachycardia is usually a rapid contraction of a normal heart in response to a condition, drug, or disease as, for examples, pain, fever, excessive thyroid hormone, exertion, excitement, low blood oxygen level (hypoxia), or stimulant drugs such as caffeine, cocaine, and amphetamines. However, in some cases, it can be a sign of heart failure, heart valve disease, or other illness. (12 Dec 1998) |

Synonym: sinus transversus, lateral sinus. Transverse pericardial sinus, a passage in the pericardial sac between the origins of the great vessels, i.e., posterior to the intrapericardial portions of the pulmonary trunk and ascending aorta and anterior to the superior vena cava and superior to the atria; it is formed as a result of the flexure of the heart tube, partially approximating the great venous and arterial vessels.

The inferior petrosal sinus arises from the cavernous sinus and runs to the internal jugular vein. Sampling of blood at this level is a valuable tool in the differential diagnosis of cushing disease, cushing syndrome, and other adrenocortical diseases. (12 Dec 1998) |
| phasic sinus arrhythmia | Sinus arrhythmia in which the irregularity is related to the phases of respiration, the rate being faster in inspiration and slower in expiration. (05 Mar 2000) |

| phrenicocostal sinus | The cleftlike extension of the pleural cavity between the diaphragm and the rib cage; pleural effusions collect here when in the upright position, and since the lung only partially enters, this is the site of thoracocentesis.

| Morgagni's sinus | The grooves between the anal columns. Synonym: Morgagni's sinus. Pockets or crypts in the columnar zone of the anal canal between the anocutaneous line and the anorectal line; the sinuses give the mucosa a scalloped appearance. Synonym: sinus anales, anal crypts, Morgagni's crypts, rectal sinuses. (05 Mar 2000) |

Synonym: sinus coronarius. (05 Mar 2000) |

Synonym: precervical sinus. (05 Mar 2000) |
| prominence of venous valvular sinus | A slight eminence on the external wall of a vein correlating with the valvular sinus immediately proximal to the leaflets of the venous valve. Synonym: agger valvae venae. (05 Mar 2000) |
