what is the meaning of sinus arrythmia?

Question

is it a respiratory disorder

Answer 1

no it is not a respiratory disorder but the two are linked,ex. the heart beats btween 60-80 bpm in a normal healthy adult, Sinus is the normal terminology for a proper rythmn or contraction of the miocardium(Heart muscle)arrythmia relates to any abnormal rhythmn or irregular heart rate, this can be to slow(bradycardia)under 50 bpm,to fast(tachycardia) or A.F which is a combination of both(some times slow before increasing rapidly to very fast), There is also svt(supra ventricular tachycardia)which kunal above is confused with, this is a life threatningcondition and sometimes can be resolved or controlled by his explanation,
The link between the heart and the lungs is quite simple to understand,the lungs transfer the oxygen into the blood stream via the avioli(microscopic grape like cells)if the brain is happy with the amount of o2 circulating around the body the heart rate and respiratory rate will stay constant,if you excercise you know you start to breath faster because you have used up more o2,the same applies if your heart is beating to fast or to slow, the brain adjust the rate of your respirations to increase the amount of o2 getting into the blood stream, This is why some people think the problem is in the respiratory system rather the circularatory, one is the consequence of the failing of the other...thanks
hope this helps explain in lay mans terms,,
good health and god luck

Definition
Carotid sinus massage involves rubbing the large part of the arterial wall at the point where the common carotid artery, located in the neck, divides into its two main branches.

Purpose
Sinus, in this case, means an area in a blood vessel that is bigger than the rest of the vessel. This is a normal dilation of the vessel. Located in the neck just below the angle of the jaw, the carotid sinus sits above the point where the carotid artery divides into its two main branches. Rubbing the carotid sinus stimulates an area in the artery wall that contains nerve endings. These nerves respond to changes in blood pressure and are capable of slowing the heart rate. The response to this simple procedure often slows a rapid heart rate (for example, atrial flutter or atrial tachycardia) and can provide important diagnostic information to the physician.

Description
The patient will be asked to lie down, with the neck fully extended and the head turned away from the side being massaged. While watching an electrocardiogram monitor, the doctor will gently touch the carotid sinus. If there is no change in the heart rate on the monitor, the pressure is applied more firmly with a gentle rotating motion. After massaging one side of the neck, the massage will be repeated on the other side. Both sides of the neck are never massaged at the same time.

Preparation
No special preparation is needed for carotid sinus massage.

Aftercare
No aftercare is required.

Risks
The physician must be sure there is no evidence of blockage in the carotid artery before performing the procedure. Massage in a blocked area might cause a clot to break loose and cause a stroke.

Normal results
Carotid sinus massage will slow the heart rate during episodes of atrial flutter, fibrillation, and some tachycardias. It has been known to stop the arrhythmia completely. If the procedure is being done to help diagnose angina pectoris, massaging the carotid sinus may make the discomfort go away.

Answer 3

Cardiac arrhythmia is a group of conditions in which the muscle contraction of the heart is irregular or is faster or slower than normal.Some arrhythmias are life-threatening medical emergencies that can cause cardiac arrest and sudden death. Others cause aggravating symptoms, such as an awareness of a different heart beat, or palpitation, which can be annoying. Some are quite benign and normal. Sinus arrhythmia is the mild acceleration followed by slowing of the normal rhythm that occurs with breathing. In adults the normal heart rate ranges from 60 beats per minute to 100 beats per minute. The normal heart beat is controlled by a small area in the upper chamber of the heart called the sinoatrial node or sinus node. The sinus node contains specialized cells that have spontaneous electrical activity that starts each normal heart beat.

Answer 5

I would be concerned, but not necessarily worried. Let's break down what you have stated. The term "marked" basically means "noticeable". The term "sinus" goes back to your high school math classes, and the "sine wave". There are four points that describe a heartbeat, and the valves opening and closing. They are Q,R,S, and T. The EKG prints out these points for several beats of the heart. Together, these four points, when graphed, resemble a sine wave. The term "normal sinus rhythm" means a regular, defect-free heartbeat. "Arrhythmia" indicates an abnormal heart rhythm. So, what your EKG is saying about you is that you have a noticeable abnormality in your heart rhythm, but that you are in sinus rhythm, which is good. I'm guessing that what your EKG is showing that instead of having a steady rhythm of, say 60-65 beats per minute, yours will beat fast for several beats, and then slow up, thus the term arrhythmia. Your case may be as simple as taking a pill once or twice per day to control your heart rate. Again, ANY abnormality in the heart rhythm must be taken seriously; however, I don't think you're going to drop dead from it between now and when you see your doctor.

Answer 6

A Respiratory Sinus Arrhythmia is a change in the heart rate that corresponds to the frequency
of respiration.

Typically the heart rate will increase during inspiration due to stimulation of the sympathetic
nervous system during this time, and the heart rate will decrease during expiration due to
stimulation of the parasympathetic nervous system. The rhythmic change in heart rate can be
attributed to varying levels of the neurotransmitters acetocholine (sympathetic) and norepinephrine
(parasympathetic) at nerve endings. However, parasympathetic activity influences heart rate by RSA
much more so than sympathetic activity.

Respiratory Cardiac Arrythmia is influenced by two factors. A reflexive factor, which consists of
arteriole response to sympathetic stimulation alters arterial blood pressure; baroreceptors and
stretch receptors in the lungs alter the heart rate accordingly in a feedback manner. Also, the
Bainbridge Reflex plays a major role in the alteration of heart rate as a result of respiration.

The second factor that controls the heart rate with respect to respiration is the central nervous
system, which connects the heart and lungs through the cardiac/vagal center of the medulla. This has
been demonstrated experimentally. It is known that Respiratory Sinus Arrythmia is the result of both
reflexes in which the heart responds to the respiratory cycle and control from the central nervous
system.

Answer 7

The heart is a muscle that works like a pump. It's divided into four chambers — two atria at the top of the heart and two ventricles at the bottom. The heart beats (contracts) when an electrical impulse from the heart's "natural pacemaker" — the sinoatrial or SA node — moves through it. The normal sequence, called the sinus rhythm, begins in the right atrium, spreads throughout the atria and to the atrioventricular (AV) node. From the AV node, the impulses (signals) travel down a group of specialized fibers (the His-Purkinje system) to all parts of the ventricles. This exact route must be followed for the heart to pump properly. As long as the electrical impulse is transmitted normally, the heart pumps and beats at a regular pace. A normal heart beats 60 to 100 times a minute.

The term arrhythmia refers to any change from the normal sequence of electrical impulses, causing abnormal heart rhythms. This can cause the heart to pump less effectively. Some arrhythmias are so brief (for example, a temporary pause or premature beat) that the overall heart rate or rhythm isn't greatly affected. But if arrhythmias last for some time, they may cause the heart rate to be too slow or too fast or the heart rhythm to be erratic.

The term tachycardia refers to a heart rate of more than 100 beats per minute. Bradycardia describes a rate of less than 60 beats per minute.

Tachycardia
A fast heart rate is called tachycardia. Tachycardias fall into two major categories. Ventricular tachycardia involves only the ventricles. Supraventricular tachycardia involves both the atria and the ventricles. The definition of "too fast" usually depends upon the person's age and physical activity.

What causes tachycardia?
Under certain conditions, the automatic firing rate of secondary pacemaker tissue may become too fast. If such an abnormal "focus" fires faster than the sinus node, it may take over control of the heart rhythm and cause tachycardia.

In another type of abnormal conduction, impulses get caught in a merry-go-round-like sequence. This process, called reentry, is a common cause of tachycardias. Regardless of their cause, tachycardias are classified by where they arise. Thus, ventricular tachycardias start in the heart's ventricles (lower chambers). Supraventricular tachycardias arise higher in the heart — either in the upper chambers (atria) or the middle region (AV node or the very beginning portion of the His-Purkinje system.)

What are the symptoms and treatments for tachycardia (rapid heart beating)?
Rapid heart beating can produce symptoms of palpitations, rapid heart action, dizziness, lightheadedness, fainting or near fainting. Heartbeats may have either a regular or irregular rhythm. Rapid heart beating in the ventricles — called ventricular tachycardia — can be life-threatening. The most serious cardiac rhythm disturbance is ventricular fibrillation, where the lower chambers quiver and the heart can't pump any blood. Collapse and sudden death follows unless medical help is provided immediately.

If treated in time, ventricular tachycardia and ventricular fibrillation can be converted into normal rhythm with electrical shock. Rapid heart beating can be controlled with medications and by identifying or destroying the focus of rhythm disturbances. One effective way of correcting these life-threatening rhythms is by using an electronic device called an implantable cardioverter defibrillator.

Bradycardia
A heart rate that's "too slow" is called bradycardia. What's "too slow" depends upon a person's age and physical activity.

What are the symptoms and treatments for bradycardia (slow heartbeat)?
A heart rhythm that's too slow can cause fatigue, dizziness, lightheadedness, fainting or near-fainting spells. These symptoms can be easily corrected by implanting an electronic pacemaker under the skin to speed up the heart rhythm as needed.

Answer 8

Irregularity of heart beat due to a variation in the sinus rhythm

Answer 9

Sinus arrhythmia: The normal increase in heart rate that occurs during inspiration (when you breathe in). This is a natural response and is more accentuated in children than adults.

Answer 10

heart disorder. Irregular beating of the heart.
