What is Paranasal Sinus?

Paranasal sinus refers to all the four sinuses that are air filled spaces communicating with nasal cavity. There sinuses are divided into four groups according to the site of their location and the bone associated with them. Let us see, what are these four sinuses?

The paranasal sinuses are divided into four groups:

Maxillary sinuses: They are also know as maxillary antra and they are the largest of all sinuses. They are located under the eye and due to the maxillary bone cheeks in this region they are called maxillary sinuses.

Frontal sinuses: These sinuses are located over the eyes which are associated with frontal bones and hence called frontal sinuses.

Ethmoid sinuses: The space between the nose and the eyes are located with paranasal sinuses called ethmoid sinuses.

Sphenoid sinuses: The sinuses located near the sphenoid bones is called sphenoid sinuses. Its located at the center of the skull and under the pituitary gland.

Now all these paranasal sinuses have some biological role to play in our body. What are these? They decrease the weight of the skull, shape the facial bones, increase resonance to voice, provide a buffer against any blow to your face, Insulate sensitive structure like dental roots, fluctuations in the nasal cavity, and protect eyes. The process of heating and humidifying is an important function of these sinuses.

All these paranasal sinuses are vulnerable to infections by bacteria and others. They can infect any of the four sinuses that we have in our facial region. When they infect the sinuses we call it sinusitis. The infections cause great trouble to the patient. When this happens this is called sinusitis. Sinus infection is not something very deadly!

What is Normal Sinus Rhythm? - Normal Sinus Rhythm in a Nutshell

Meaning of what is normal sinus rhythm

An electrical impulse is generated by the sinus node, it moves through the right and left atrial muscles fabricating an electrical charge which could be seen in an electrocardiogram (ECG) by the p-wave. They continue their movement through specialized tissues known as atrioventricular node which carries electricity at a slower pace. There is a small pause (PR interval) which helps in the blood to be emptied into the ventricles from the atria, before the ventricle contracts to push the blood out into the body. This could be seen in the ECG as QRS complex of waves. The T-waves denotes the electrical changes in the ventricles while they are relaxing or resetting of the heart for the subsequent beat. This cycle repeats once again after a short gap.

In simple terms what is normal sinus rhythm. "It is an electrical pattern of the heart beat".

Normal sinus rhythms are found mostly in healthy heart. Heart runs on electrical impulses that stimulates it chambers (atria and ventricles) to contract and expand. With each heart beat the blood is pumped through out the body. Normal heart beat is between 60 and 100 beats per minute. There is no fixed heart rate; it may vary from a child to adult. A new born child's heart rate is 150 beats per minute, whereas a five year old has 100 beats per minute. In an adult it is 80 beats per minute. The S-A node or sinoatrial node is where the electrical impulse begins. This is otherwise known as the natural pacemaker of the heart. What is normal sinus rhythm detection methodology? This can be detected through ECG (Electrocardiogram). In a normal sinus rhythm the peaks are evenly placed.

What is normal sinus rhythm classification?

A normal heart rhythm with a fast heart rate is called sinus tachycardia. The impulses are normal bit the pace is faster. This is the case when you exercise or when you are excited.

A normal hearth rhythm with a slow heart rate is called sinus bradycardia. It is seen during medications such as beta blockers.
