A heart attack is a potentially life-threatening medical emergency that can lead to cardiac arrest or death. Heart attacks are common, too, with an estimated 805,000 people in the United States ...
Electrodes can be inserted into and through the coronary sinus to study the electrophysiology of the heart. This includes for a coronary sinus electrogram. [5] The coronary sinus connects directly with the right atrium. It will dilate as a result of any condition that causes elevated right atrial pressure, such as pulmonary hypertension. [7]
Sinus node dysfunction also known as sick sinus syndrome is a group of irregular heartbeat conditions caused by faulty electrical signals of the heart. When the heart's sinoatrial node is defective, the heart's rhythms become abnormal—typically too slow or exhibiting pauses in its function or a combination, and very rarely faster than normal ...
The oblique sinus is an inverted J-shaped reflection of the venae cavae and pulmonary veins. [2] It lies behind the atria (particularly the left atrium), [1] and in between left and right pulmonary veins. The transverse sinus is the tunnel-shaped passage posterior to the aorta and pulmonary trunk, and anterior to the superior vena cava.
Myocardial infarction; Other names: Acute myocardial infarction (AMI), heart attack: A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing blood flow downstream to the heart muscle.
Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans). [1] The normal resting heart rate is 60–90 bpm in an average adult. [2]
The base is formed by the coronary sinus orifice and the vestibule of the right atrium, and the hypotenuse is formed by the tendon of Todaro, which is often a continuation off the Eustachian valve. Other structures near to it are the membranous septum and the Eustachian ridge. Variations in the size of Koch's triangle are common.
For many people, sinus pain is not necessarily the picture of migraine that they have in their mind's eye, she says, but migraine attacks do frequently cause sinus pressure and pain.
