Arrhythmia :-
Arrhythmia is also called irregular heartbeat or dysrhythmia.
This is a change in the rhythm of your heartbeat. Your heart may beat very fast (tachycardia) or very slow (bradycardia). Your heartbeat can be irregular. This take place if your heart skips a beat or has an extra beat. Arrhythmias are usual. For most people, they are minor and not critical. However, they can be serious or life-threatening. Arrhythmias are more critical if you have any other heart problems.
Types of Arrhythmia :-
There are many types of arrhythmias. The type that begin in the lower chambers of the heart (ventricles) can be very bad than those that start in the upper chambers (atria).
• Atrialfibrillation :
Your heart beats unevenly and very fast. This type needs treatment. This can higer your risk of stroke.
• Paroxysmal atrial tachycardia :
Your heart has episodes of beating very fast. This can lead to discomfort and It is not critical.
• Ectopic beats :
Your heart has an extra beat. Take treatment if you have many extra beats in a row and/or other problems with your heart. For example heart disease and congenital heart disease.
• Ventricular tachycardia and ventricular fibrillation :
In this the heart beats very fast. It can not pump sufficient These types are critical and needs immediate treatment.
Symptoms of Arrhythmia :-
Sometimes, people feel their heart race or skip a beat. These can be brought on by strong emotions or exercise. They commonly are not a reason for alarm. Inform to your doctor if you have symptoms. You can have an arrhythmia or other heart problem. Possible signs of a more critical problem involve:
• Palpitations or fast thumping in your chest.
• Feeling tired or light-headed.
• Passing out.
• Shortness of breath
• Chest pain.
Get care right away if symptoms take place and you have a history of heart disease or had an heart attacks.
Causes of Arrhythmia :-
Your heart has 4 chambers. The walls of your heart contract together to push blood from the chambers. Electrical signals in your heart’s natural “pacemaker” (sinoatrial node) control these. The rate of contractions is affected by the nerve impulses and harmones. A problem in any of these areas can lead to an arrhythmia.
Heart disease is the most usual cause of the more critical forms of arrhythmias. Arrhythmias can be lead by congenital heart disease (CHD), abnormal heart valve function, and heart failure. Minor arrhythmias can be caused by other factors. These incolve alcohol abuse, smoking, caffeine, stress, or exercise. Arrhythmias can also take place for no known reason.
Diagnosis of Arrhythmia :-
Your doctor can perform a physical exam and can discuss your symptoms. Your doctor will ask about your heart and health history. Your doctor will do tests like an electrocardiogram (ECG or EKG). During this test, you will lie down and the doctor will monitor your heartbeat.
Your doctor can do an exercise or stress test. This consists of monitoring your heart while you walk on a treadmill. You can be given medications to speed up your heartbeat. This can help out finding an underlying heart disease.
Another way to track your heart is to wear a machine known as Holter monitor. It tracks your heart’s rhythms for 24 hours. If your doctor wants to observe your heart for more than 24 hours, he or she may give you an event recorder. It track the samples of your heart’s rhythms for a couple of days or more. The doctor can run other tests to get information about your heart.
Prevention of Arrhythmia :-
You can cure some types of arrhythmias with lifestyle changes. Maximum use of alcohol and stop smoking. Maintain a healthy weight by doing diet and exercise. Work with your doctor to control heart disease or other health problems.
Treatment of Arrhythmia :-
Treatment depends on the type of arrhythmia you are having. Some lenient arrhythmias can not need treatment. Other types can be treated with medicine. Critical cases needs additional treatment, including:
• Artificial pacemaker -
In this the electronic device is placed under the skin on your chest. It helps your heart to maintain a regular beat.
• Cardiac defibrillation -
A short electric shock can stop an abnormal rhythm and restore a normal one.
• Procedures can correct specific types of arrhythmias -
If the arrhythmia take place in a specific area of your heart, that part can be removed. A procedure known as cardiac ablation can kill the tissue in your heart that give rise to the arrhythmia.
Arrhythmias lead by health problems must be properly treated and managed.
