Why do they use the term "sinus rythmn" ?

Question

when talking about a heart beat when the sinus' is/are above your nose?

Answer 1

Sinus rhythm is a term used in medicine to describe the normal beating of the heart, as measured by an electrocardiogram (ECG). It has certain generic features that serve as hallmarks for comparison with normal ECGs. It has nothing to do with nasal sinuses.

Answer 2

The healthy heart beats at a regular rhythm.the rate varies according to the stress put on it e.g.running beats faster. The "Master controller" of the heart rate is a small piece of muscle in the part of the heart called the right atrium-the sino-atrial node SA node also known as the sinus node. The electrical impulse spreads out from this point controlling the heart rate and rhythm If it is beating regularly under control it is known as sinus rhythm.
The word Sinus has more than one meaning and therefore can be used for maxillary (air spaces) sinus/pilonidal(abnormal opening) sinus etc

Answer 3

Sinus rhythm refers to the heart rate that originates in the upper chambers of the heart. Sinus rhythm is considered a normal heart pattern of the electrical conduction system of the heart. Some people do not like to use the word " normal ", also known as NSR ( normal sinus rhythm). We have sinuses in the nose, in the cheek region, above of eyes, to name a few. I hope that this helps.

Answer 4

In reality, this isn't an Allergies category question. A sinus is any cavity or chamber and sinus rhythm refers to a cardiac rhythm that is initiated in the sinus node of the heart. The sinus node is a cluster of cells in the right atrial wall, near the opening of the superior vena cava.

In response to your statement that "the sinus is/are above your nose", only the frontal sinuses are above the eyes and nose. The maxillary sinuses are in the upper jaw and the sphenoidal sinuses are in the sphenoid bone at the base of the skull.

Answer 5

The "sinus rhythm" is the normal regular rhythm of the heart set by the natural pacemaker of the heart called the sinoatrial (or sinus) node. It is located in the wall of the right atrium (the right upper chamber of the heart). Normal cardiac impulses start there and are transmitted to the atria and down to the ventricles (the lower chambers of the heart).

Sinus arrhythmia refers to the normal increase in heart rate that occurs during inspiration (when you breathe in). This is a normal response and is more accentuated in children than adults. Uncoordinated arrhythmia, or twitching of the heart muscles, is called ventricular fibrillation (or V-fib). Without immediate treatment, it can result in death.

Sinus tachycardia refers to a fast heartbeat (tachycardia) because of rapid firing of the sinoatrial (sinus) node. This occurs in response to exercise, exertion, excitement, pain, fever, excessive thyroid hormone, low blood oxygen (hypoxia), stimulant drugs (such as caffeine), etc.

The lack of normal sinus rhythm is an arrhythmia, an abnormal heart rhythm.
