Arrhythmia is a term used to describe a group of heart disorders where the regular heart beating is disturbed.
Arrhythmia is a term used to describe a group of heart disorders where the regular heart beating is disturbed.Atrial fibrillation is the most common condition in this group. The severity of arrhythmia varies from extremely low where the heart is healthy and the problem does not cause serious issues and those when strokes and heart diseases may occur. Extreme cases may be fatal. Arrhythmia can happen with irregular rate of the heart. The regular heart-rate can range between 50 to 100 beats per minute. If arrhythmia happens with regular or rather slow heart beat of about 60 beats a minute, in this case the disorder is called bradarrhythmia. And if the rate of heart exceeds 100 beats every minute, the condition is generally called tachyarrhythmias. There are four chambers in the heart called auricles. They contract pumping the blood. The contractions rate is regulated by the sinoatrial node. The functioning of the sinoatrial node is controlled by the nervous impulses coming from the hormones and the brain. Any kind of abnormality in the factors controlling the heart contractions can cause arrhythmia. Transitory arrhythmias are caused because of idiosyncratic reactions and allergies people have to drinks or foods. Arrhythmia can be the result from nicotine or cocaine addiction. Among other causes of arrhythmia there is hypertension, coronary heart diseases and heart defects. Symptoms are usually not a helpful means to detect arrhythmia as this condition provokes none or very few of them. Most of the arrhythmia conditions cause shortness, chest discomfort, dizziness, quivering, lightheadedness, and heart fluttering or pounding, forceful and painful heartbeats. In less severe cases, the immune system controls arrhythmia but in serious cases, treatment is needed. It can be in the form of medications, implantable artificial pacemakers/defibrillators or cardioversion. In the cardioversion, electric current is used; it is applied across the chest wall to the heart. This treatment is given for pulsed supraventricular and ventricular tachycardia. Ventricular fibrillation and pulseless ventricular tachycardia are treated with defibrillation, where more electricity is delivered to the heart than in cardioversion. Other types of treatment include CRT, arrhythmic therapy medication, catheter ablation, cardiac resynchronization therapy and etc.
All the treatments for arrhythmia are intended to change the electrical signals delivered to your heart thus mitigating or preventing an abnormality present in the heart rate.
