Causes of Cardiac Arrest
A problem in the heartbeats of the individual as a result of the electoral system of the heart is the main cause of sudden heart arrest. The electoral system of the heart controls the rhythm and rate of the heartbeat. If something goes wrong in the body the heart can beat fast and the individual faces abnormal heart rhythms. Although the arrhythmias are short and harmless sometimes it causes serious consequences. In the lower chamber of the heart, the most fatal cardiac arrest occurs. Rapid erratic impulses cause serious quivers in the heart rather than pumping the blood.
Heart problems that can cause a sudden cardiac arrest
In people without heart disease, a sudden cardiac arrest may occur. However, a life-threatening arrhythmia usually develops in a person with pre-existing, possibly undiagnosed heart disease. The conditions include:
Coronary Artery Disease
In most cases of sudden cardiac arrest cholesterol and other debris, blocks the arteries due to which the flow of blood to the heart is reduced.
Heart Attack
When a heart attack occurs, often as a result of severe coronary heart disease, it can trigger ventricular fibrillation and sudden cardiac arrest. In addition, a heart attack can leave scar tissue in the heart. Electrical shorts around the scar tissue can cause an abnormal heart rhythm.
Large heart (cardiomyopathy)
This occurs especially when the muscle walls of your heart expand and expand or thicken. Then the heart muscle is abnormal, which often leads to arrhythmias.
Heart valve disease.
Leakage or narrowing of the heart valves can cause stretching or thickening of the heart muscle. Increasing or weakening the spaces due to the tension of a closed or leaking valve increases the risk of arrhythmias.
Congenital heart disease
When a sudden cardiac arrest occurs in children or adolescents, it may be due to heart failure that occurred at birth (congenital heart disease). Adults undergoing surgery for congenital heart disease still have an increased risk of sudden cardiac arrest.
Electrical problems in the heart.
In some people, the problem is more in the electrical system of the heart than in the heart muscle or heart valves. These are referred to as primary cardiac arrhythmias and include conditions such as Brugada syndrome and long QT syndrome.
