So if you ask. 'What is sinus arrhythmia?' then there are other things too associated with it. However, a sinus arrhythmia indeed does not mean that an individual is suffering from an unwarranted disease, specially no heart disease as such. Many arrhythmias, specifically arrhythmia is found to take place in people who do not have the least symptom or inkling of any heart disease. In most of the cases, even if an arrhythmia is found to exist alongside a heart disease, it is in all likely possibility that the patient will likely die of the heart disease than of the arrhythmia, specifically sinus arrhythmia.

And a word of caution when you say,’ What is sinus arrhythmia?', that sinus bradycardia is not the same as sinus arrhythmia. The symptoms of both the forms of heart-beat irregularities are divergent and the manifestations are different. Sinus arrhythmia affects the vagus nerve which is responsible for activating the nervous system-triggered parasympathetic input which regulates the heart beat. This systematic failure of the medulla oblongata results in the condition which is termed as sinus arrhythmia. To put it in easy words, the vagus nerve is left unstimulated resulting in the wrong signals to the heart and the subsequent decline in pitch of the heart rate. This is what sinus arrhythmia is.

Cardiac Arrhythmias

Cardiac arrhythmia is a group of conditions in which the electrical activity of the heart is irregular or is faster or slower than normal. Cardiac arrhythmias comprise any abnormality or pertubation in the normal activation sequence of the myocardium. Arrhythmias stem from several causes. The heart’s natural timekeeper—a little mass of special cells called the sinus node—can malfunction and develop an abnormal electrical impulse rate. CPR can prolong the survival of the brain in the lack of a normal pulse, but defibrillation is the intervention which is most likely to restore a more healthful heart rhythm. A slow rhythm, known as bradycardia (less than 60 beats/min), is regularly not life threatening, but may cause symptoms. When it causes symptoms implantation of a constant pacemaker may be required. Either dysrhythmia needs for medical attention to evaluate the risks associated with the arrhythmia. The signs and symptoms of cardiac arrhythmias can range from fully asymptomatic to loss of consciousness or sudden cardiac death.

Causes, Symptoms and Treatment

Complaints like lightheadedness, dizziness, quivering, shortness of breath, chest discomfort, heart fluttering or pounding, and forceful or painful extra beats are generally reported with a variety of arrhythmias. Beats are generated by electrical impulses in the atria (top chambers of the heart) and are then conducted to the ventricles, where they make the powerful muscle contraction that pumps blood. People may have allergies or idiosyncratic reactions to many other foods and beverages that cause transitory arrhythmias.

Treatment for Cardiac Arrhythmias Tips

1. Using a little, battery-powered generator to deliver timed, electrical impulses to the heart muscle through very small wire leads.

2. The treatment for some patients is a technique called cardiac ablation.

3. Magnetic Guidance in the Heart While transcatheter ablation is very effective, it can be hard.

4. Stereotaxis Niobe Magnetic Navigation System uses 2 superconductive magnets, a magnetic-tipped guide wire and improved computer imaging techniques.

5. Atrial fibrillation can also be treated through a procedure, e.g. pulmonary vein isolation.
