The coronary sinus ostium is an opening located between the inferior vena cava and the tricuspid valve on the inferior aspect of the interatrial septum; forms a corner of Koch's triangle; its valve is referred to as the Thebesian valve.

Fever Swelling in your face Other kinds of recurring headaches, like migraines or tension headaches, are often mistaken for sinus headaches. Because the treatment you need depends on what.

Symptoms Causes of Ectopic Beats Diagnosis More "Ectopic" means something that is in an odd place or position. In the case of an ectopic beat, that oddly placed something is your heartbeat. You.

Sinus tachycardia refers to an increased heart rate that exceeds 100 beats per minute (bpm).The sinus node, or sinoatrial node, is a bundle of specialized electrical cells in the right upper.

Summary. A sinus arrhythmia refers to a problem with the sinus node of the heart. This controls the rhythm of the heart and can be fast (tachycardia) or slow (bradycardia). This article looks.

A normal heartbeat is referred to as normal sinus rhythm (NSR). An abnormally slow heartbeat is called bradycardia, while an abnormally fast heartbeat is called tachycardia.

Sinus rhythm refers to the rhythm of your heartbeat, determined by the sinus node of your heart. The sinus node creates an electrical pulse that travels through your heart muscle, causing.

Sinus rhythm refers to the normal electrical activity of the heart, where the heart rate and rhythm are initiated and controlled by the sinoatrial (SA) node. It’s characterized by a regular heartbeat with 60 to 100 beats per minute in adults. Sinus rhythm is important for maintaining proper blood flow and oxygenation throughout the body.

Summary A sinus arrhythmia refers to a problem with the sinus node of the heart. This controls the rhythm of the heart and can be fast (tachycardia) or slow (bradycardia). This article looks.

4. Determine Your Heart Rate. Look at the EKG/ECG to see if the rate is regular and how fast the heart is beating; both are important for rhythm interpretation. The pace at which a rhythm is conducting can help determine the stability of the rhythm. A stable rhythm often correlates with a stable patient.

Normal sinus rhythm (NSR) is the rhythm that originates from the sinus node and describes the characteristic rhythm of the healthy human heart. The rate in NSR is generally regular but will vary depending on autonomic inputs into the sinus node. When there is irregularity in the sinus rate, it is termed "sinus arrhythmia."
