Cardiac Arrest: Causes, Symptoms and Prevention

Cardiac arrest is responsible for no less than 7 million deaths world. By way of definition, it appears sudden cessation of cardiac output due to failure of the heart muscle to contract properly. It is worthy of note that cardiac arrest differs from heart failure in which the heart pumps blood still, albeit less or heart attack (myocardial infarction) where the blood supply to the heart is blocked and consequent death of the affected heart muscle. Clearly, cardiac arrest is a medical emergency that can lead to preventable death in a few minutes without surgical intervention. In fact, speculations are rife that the death of Hon captain and coach of the Super Eagles, Stephen Keshi may be due to a cardiac arrest.

In light of the foregoing, there are a few things you should know about cardiac arrest.

1. It can lead to death within minutes

Sadly, 95% of patients who go into cardiac arrest never survive it. Why? If emergency visitors access from the site of the incident to the hospital, chances of survival are very slim. However, an intervention as simple as chest compression can be life-saving if started immediately. Once the heart stopped pumping blood, lower body organs especially the brain are deprived of oxygen and cover.

2. What is the cause of cardiac arrest?

Cardiac arrest effect throughout the electrical system of the heart malfunctions result of irregular heart rhythms (arrhythmias). A common type of arrhythmia is ventricular fibrillation, a condition where the ventricles beat chaotically and grow like a bag of worms with an output. Several factors (cardiac and noncardiac) can cause cardiac arrest. However, about 60-70% of cases result from coronary artery disease, or heart attack. Other important causes include cardiomyopathy, heart failure, injury, hypovolemia (e.g from excess bleeding), drowning, poisoning, low blood sugar, very low temperature and metabolic disorders. Similarly, risks such as smoking, excess alcohol and lack of physical exercise and obesity and diabetes can increase the chances of men experiencing cardiac arrest

3. What are the signs and symptoms?

It ordered the treatment that a cardiac arrest can give a warning. However, it may be preceded by symptoms such as dizziness, breathlessness, Fainting, Blackouts and throwing others. Immediately the man goes into attack, stroke became undetectable became unconscious since the brain shut down. The breath is crazy, and he immediately stopped.

4. How was cardiac arrest diagnosed?

Traditionally, the diagnosis of cardiac arrest in the absence of carotid pulse in a variable that is unconscious. In addition, surgical tests will be carried out to understand the underlying cause of cardiac arrest in order to prevent a recurrence among survivors. Such browsers include electrocardiography diagnose another arrhythmia, echocardiography, toxicology screening and others.

5. How is cardiac arrest followed?

Research has shown that early commencement of cardiopulmonary resuscitation (CPR) and defibrillation is key to ensure the best results in cardiac arrest. Therefore, the chain of survival involves early stage captures witnesses who called for help immediately when starting an emergency CPR to buy time before the defibrillator can be reached. Effective CPR related chest compressions to maintain circulation to deadly respiratory organs saved for oxygenation. As soon as it is confirmed that the attack is shockable, an automated external defibrillator (AED) is used to shock the heart back to normal rhythm while CPR was continued until pulse returns. Medications such as adrenaline, atropine, vasopressin and amiodarone also used in some cases of cardiac arrest.

6. prevent cardiac arrest

The survivors of cardiac arrest, the need to prevent a repeat attack cannot be overstressed. They must adopt a heart-healthy lifestyles, including quitting smoking or excess alcohol, regular exercises, using low-salt, low-fat diets with plenty of fruits and vegetables.
Finally, the need to mention that such persons need regular follow-up visits to assess the condition of the heart.
