Heart Arrhythmia

Heart Arrhythmia is an irregular heart beat also known as dysrhythmia that causes the irregular heart rate.


A regular heart rate of 50-100 beats per minute is the expected heart rate for a healthy person. Unusual heart rates and Heart Arrhythmia don’t automatically happen together. A person with a normal heart rate or with an abnormally slow heart rate (bradycardia) may have arrhythmia that is termed as bradyarrhythmia. Arrhythmia can as well happen along with fast heart rates (tachycardia) called as tachyarrhythmia.

What are the Causes of Heart Arrhythmia?

Heart Arrhythmia can be caused by various conditions concerning obviously the heart. The causes are associated to diseases which can affect the normal functions of the heart which is to regularly and efficiently pump blood to other essential parts of the body. The diseases that contribute to the occurrence of this condition are electrolyte imbalances in the blood such as potassium and sodium; coronary artery diseases like atherosclerosis; changes in the heart muscle like cardiomyopathy; damage from a myocardial infarction; healing after a surgery of the heart.

What are the Types of Heart Arrhythmia?

There are various types of arrhythmias that significantly differ from each other. Premature Atrial Contractions are extra heart beats that occur earlier that the first heart sound that came from the atria, more specifically the heart’s upper chambers. This type is harmless and does not necessarily need treatment.

Premature Ventricular Contractions belong to the most typical arrhythmias to occur in the majority of people with or without a heart disease. This is described as a skipped heart beat that all of us intermittently experience. For a few people, it can be linked with too much nicotine and caffeine, too much activities and stress. But for some, PVCs can originate from an electrolyte imbalance or heart disorder. Patients with a great number of PVCs and symptoms linked with it must be seen by a physician. Fortunately for some people, this condition is not fatal and does not need immediate medical interventions.

Atrial Fibrillation is a very typical abnormal heart rhythm that results to the upper chambers of the heart, atria, to abnormally contract. Atrial Flutter is a type of arrhythmia that originates from one or more fast circuits in the atria. It is commonly more regular and structured than atrial fibrillation. This condition can happen to majority of people with heart disorders and in patients post heart surgery during its first week and frequently converts into atrial fibrillation.

Paroxysmal Supraventricular Tachycardia is a fast heart rate that is commonly with a regular rhythm coming from the upper portions of the ventricles. It normally commences and ends abruptly. Accessory Pathway Tachycardia is a fast heart rate because of an extra irregular connection or pathway between the ventricles and atria. The impulses pass through the added pathways also through the normal route.

AV Nodal Reentrant Tachycardia is a fast heart rate as a result of more than one pathway all the way through the AV node. It can result to palpitations, heart failure and fainting. In several cases, can be concluded using maneuvers even simple ones such as bearing down and breathing in and others executed by a skilled medical professional. Some medications can also stop this condition.

Ventricular Tachycardia is a type of Heart Arrhythmia resulting from the ventricles or lower chambers of the heart. The fast rate averts the heart to fill sufficiently with blood. Consequently, less blood will be able to propel out to the body. This can be a serious form of Heart Arrhythmia specifically in patients with heart disorders and may be linked with the manifestations of symptoms. Ventricular Fibrillation is a disorganized and erratic release of impulses from the ventricles. The ventricles shiver and are not capable to pump or contract blood to the body. This condition is a medical emergency that should be taken care of with CPR or Cardiopulmonary resuscitation and defibrillation immediately.

Sinus Node Dysfunction is a sluggish heart rate due to an irregular SA node that significantly dysfunction on the latter part of the condition which causes manifestations to be manages by a pacemaker. Heart Block is an impediment or complete blockage of the electrical impulses as it passes through the SA node to the ventricle. The degree of the delay or block may happen in the Purkinje fibres or AV node. The heart might contract irregularly and frequently more slowly. If severe, the heart block is managed using a pacemaker.

What is the Symptoms Heart Disease- Heart Arrhythmia?

A Heart Arrhythmia can be a silent but growing disease that causes many symptoms. A physician can discover an abnormal heart beat for the period of a physical assessment by taking the pulse of the patient or using an Electrocardiogram (ECG). Symptoms Heart Disease may include pounding in the chest, light headedness, fainting, and chest discomfort, shortness of breath, fatigue, weakness and palpitations. It is important to recognize the symptoms to be able to manage it on its early stage.
