Sinus Arrhythmia | Symptoms | Diagnose And Treatment

Sinus Arrhythmia

Sinus Arrhythmia: It is essential to know first what an arrhythmia is. Before trying to understand Sinus Arrhythmia. This medical term refers to irregular and abnormal changes in the heartbeat of the person.

Sinus Arrhythmia often explained as the heart slowing down in a somewhat anxious state when a person is breathing out. During this state, the heartbeat also increases when the person is inhaling.

This abnormal behavior of the heart deemed dangerous and even fatal to the person if this condition is not detected, and sinus arrhythmia treatment performed quickly.

There are four main types of arrhythmia.

  • Premature (extra) beats
  • Supraventricular arrhythmias
  • Ventricular arrhythmias
  • Bradyarrhythmias

Premature (Extra) Beats

This is the most common type of arrhythmia. It is harmless mostly and does not cause any symptoms. In most cases, premature beats occur naturally and require no treatment, but certain heart diseases can cause this.

However, it may also occur due to stress, over-exercising, or even too much caffeine.

Supraventricular Arrhythmias

Fast heart rates (tachycardias) that begin in the atria or the atrioventricular node. Some types of supraventricular arrhythmias include atrial fibrillation (AF), atrial flutter. Paroxysmal supraventricular tachycardia (PSVT) and Wolff-Parkinson-White (WPW) syndrome.

Atrial Fibrillation (AF)

AF refers to the swift and irregular contraction of the atria causing disorganized, rapid, and irregular rhythm.

This allows blood to pool in the left atrium and form clots that may travel to the brain. It is the most common type of severe arrhythmia, which may cause a stroke or heart failure.

Atrial Flutter

Similar to atrial fibrillation, but its rhythm is fast and regular instead. It is much less common than atrial fibrillation, but it has similar symptoms and complications.

Paroxysmal Supraventricular Tachycardia (PSVT)

PSVT is a rapid heart rate that begins and ends suddenly. Extra heartbeats caused by electrical signals that re-enter the atria after traveling to the ventricles. This type of arrhythmia is usually not dangerous.

Wolff-Parkinson-White (WPW)

This is a type of PSVT. The heart’s electrical signals travel along an extra pathway from the atria to the ventricles, which disrupts the timing and can cause the ventricles to beat very fast. This can be life-threatening.

Ventricular Arrhythmias

These start in the ventricles and can be risky, as a rule requiring quick medicinal consideration. Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation.

Coronary artery disease (CAD), heart attack, the weakened heart muscle can cause this.

Ventricular Tachycardia

Fast, regular beating of the ventricles that may last only for a few seconds or much longer. Ventricular tachycardia that goes on for beyond what a couple of moments can be risky and can transform into increasingly dangerous arrhythmias, for example, ventricular fibrillation.

Ventricular Fibrillation

It occurs when the ventricles quiver instead of pumping generally due to the disorganized electrical signals. This causes the ventricles to function as a pump to circulate blood.

Ventricular fibrillation tends to occur mostly in diseased hearts. However, it can also occur in otherwise healthy individuals and can lead to sudden death.

Sinus Arrhythmia

Sinus Arrhythmia Symptoms

There are many forms of Arrhythmia and Sinus Arrhythmia is the most common of all and although it can affect anyone, it usually affects adults older than the age of seventy.

Sinus Arrhythmia symptoms include:

  • Missed beats, skips, thumps, butterflies, fluttering, or racing
  • May come in single or multiple beats
  • May be felt anywhere from the stomach to the head
  • Dizziness
  • Fainting
  • Chest pain
  • Shortness of breath

Diagnose

  • Blood tests
  • Electrocardiogram (ECG)
  • Heart monitor

Sinus Arrhythmia Treatment

For most patients who suffer from some types of arrhythmia, especially atrial fibrillation, doctors usually prescribe blood-thinning medications.

The most common one is warfarin, although this medication is potent with some side effects.

If patients prescribed with this, doctors’ instructions must strictly follow before taking it. Unless patients subsequently opt for surgical procedures, for example, catheter ablation, taking such medications is lifelong.

Patients who taking warfarin are required to make regular blood tests to determine how it is helping as an anticoagulant agent. Called International Normalised Ratio or INR, the doctor will decide if it meets the requirement of between 2-3 for patients taking warfarin.

For patients not on warfarin, the acceptable reading for INR is ’1′. This test will provide appropriate treatment given by the doctor. For example, if the INR is too high, this may cause bleeding, and if it is too low, it means patients’ blood could clot.

Blood clotting in the heart is dangerous as it can lead to a person getting a stroke called a transient ischaemic attack, when blood stops flowing to the brain.

Thankfully there are many newer drugs besides warfarin that doctors can prescribe to patients depending on how responsive patients are to the drugs. The disadvantage of using warfarin is that this drug reacts with some typical food like green vegetables.

So patients have to change their diet. Otherwise, their INR becomes very unstable and could pose a real danger. Newer drugs do not have this food reaction.

However, the downside is that these newer drugs are much more expensive, especially since it is going to be a lifelong medication for the patients.

Sinus Arrhythmia – Medical Explanation

The name associated with the pacemaker of the heart is known as the sinoatrial node. In an average person, the cardiac stimulus begins from the right upper chamber of the heart, traveling the atrica downwards into the lower chamber called ventricles.

Sinus tachycardia is the name used to describe the fast movement of the heartbeat. A rapid heartbeat can be a result of an exercise. A person’s getting overexcited when pain experienced, and this leads to the secretion of the thyroid hormone.

So the absence or decrease of normal sinus rhythm is known as arrhythmia, which is also known as abnormal heart rhythm.

Sinus Arrhythmia – Explained Simply

You can view your heart as having a natural pacemaker that helps in the continuous beating every day of your life. This pacemaker can be found in your heart chamber located on your upper right side and is called the sinus node.

This node is responsible for generating electrical impulses continuously. When a person suffers from this type of Arrhythmia, this pattern is somewhat changed, and it affects the normal heartbeat rhythm to become seriously threatening to your health if left untreated.

The heart function becomes abnormal, and in some severe cases, the heart can even stop beating for a short time before resuming beating again.

Types Of Abnormal Heart Rhythms Commonly Found In Children

If your child diagnosed with any arrhythmias. Such as Supraventricular Tachycardia or commonly called SVT. Doctors may prescribe antiarrhythmic medication as a treatment.

This would help to regulate and control the heart rate and rhythm. Doctors may also suggest doing Catheter Ablation which is an invasive procedure.

Ensure Sinus Arrhythmia Treatment Early

Most of these sinus rhythms thankfully are not fatal, so if a person has been diagnosed with this medical condition, it is not a death penalty, and you won’t die from it unless the patient is very old and weak.

This medical condition is treatable. If it is detected early and treated by your doctor. Most cases of Sinus Arrhythmia impact just your vagus nerve, which causes your heartbeat to become irregular.

Sinus Bradycardia with Sinus Arrhythmia

What is Sinus Bradycardia with Sinus Arrhythmia, and just how did this condition come about. We ran a check from CMBI which states that:

“Sinus Bradycardia is a rhythm in which fewer than the average number of impulses arise from the sinoatrial (SA) node.

The average heart rate has been considered historically to range from 60 to 100 beats/min, with Sinus Bradycardia defined as a sinus rhythm with a rate below 55 to 60 beats/min.

A study in 500 normal subjects using an ECG (electrocardiographically) recorded heart rate found the mean afternoon heart rate.

For men and women to be about 70 beats/min with two standard deviation limits of 46 and 93 beats/min in men and 51 and 95 beats/min for women; there no significant age-related effect.”

Wikipedia also describes Sinus Bradycardia as a heart rhythm that originates from the sinus node and has a rate of under 60 beats per minute.

What is Sinus Bradycardia Symptoms?

There are usually no significant symptoms for Sinus Bradycardia, although a small minority of patients do report getting dizziness and feeling lightheaded. Some extreme cases include experiences of chest pain and shortness of breath.

This medical condition often caused when the fibrosis of the sinus node and the surround tissues have degenerated. The doctor will usually discuss with the patient to identify the cause and recommend an appropriate treatment.

The medical explanations for Sinus Bradycardia usually called the sinoatrial node (SA node) disorder or sometimes called sick sinus syndrome and atrioventricular node (AV node) disorder. The AV node disorder may sometimes be acquired even as early as birth and are more common among elderly patients.

Wikipedia says Bradycardia is not necessarily problematic. People who consistently practice sports may have sinus bradycardia on the grounds that their trained hearts can pump enough blood in each contraction to allow a low resting heart rate.
