12 Cardiac Arrest Questions and Answers: Know its Anatomy!

Sudden cardiac arrest occurs when the heart stops beating and the oxygen is not supplied to the other vital organs of the body. Know more about it in detail.


Our heart is the major pumping organ of the heart, which controls the circulation of the blood of the entire body. The deoxygenated blood from the organs is transported by the veins to the heart and the oxygenated blood is carried out by the arteries from the heart to the organs of the body.

The proper functioning of the heart depends on the conduction of electrical signals appropriately, muscles of the heart work against the conduction signal and the efficient opening & closing of the heart’s valves. But if a slight abnormality occurs in the heart’s structure or physiology then it’ll lead to the serious medical emergencies.

Angina, Cardiac Arrest, and Heart Attack are the most common causes of the sudden death in all over the world. Today, we will discuss about the Cardiac Arrest in detail and we’ll also elaborate about the preventive measures of the cardiac arrest. So, read the below description to know the minors and majors of the cardiac arrest.

1. What is the cardiac arrest?

What is Cardiac Arrest

Sudden cardiac arrest occurs when the heart stops beating and the oxygen is not supplied to the other vital organs of the body. Additionally, if the immediate measures are not taken to restore the cardiac arrest, death occurs within minutes.

Simply, cardiac arrest is the cessation of the function of the heart due to the short circuit occurs in the electrical system of the heart, due to which the heart beating mechanism is regulated.

When the electrical system is stopped, the conduction of the electric signals will not be activated and it’ll fail to contract the heart muscles for pumping the blood in the heart. Without the fresh oxygen supply to the brain, the brain cells will die within minutes.

2. What are the common signs and symptoms of the cardiac arrest?

Cardiac arrest symptoms are sudden and life-threatening, the most common signs and symptoms are,

  • Diminished pulse rate

  • The difficulty of breathing

  • Fainting/dizziness

  • Sudden collapse

  • Palpitations

But the cardiac arrest has no warning or alarming signs which we can predict earlier and treat it immediately.

3. What are the most common causes of the cardiac arrest?

Though, cardiac arrest occurs due to many reasons, but ventricular fibrillation is the most common cause of cardiac arrest. Coronary artery disease is also another cause of the cardiac arrest in which the lack of oxygen occurs, like that in choking.

Valvular heart disease can also lead to the cardiac arrest due to the narrowing of the heart’s valves and eventually, it’ll compromise the blood pumping of the heart. If the chambers become enlarged and its walls are stretched, the risk of Arrhythmia is also increased.

4. How can we classify the cardiac arrest?

It is divided into two classifications, shockable and non-shockable rhythms, investigated on the basis of the ECG. The ventricular fibrillation and ventricular tachycardia fall in the shockable rhythm and non-shockable rhythms are asystoles and pulseless electrical rhythms.

But the most dangerous are the shockable rhythms which result in the death rapidly and the non-shockable rhythms can be treated and patient’s normal heart rate can be achieved.

5. What are the risk factors of the cardiac arrest?

Risk factors are the alarming signs that you can become the victim of the cardiac arrest if the risk factors are not controlled. The coronary artery disease is linked with the cardiac arrest but other conditions like smoking, high blood pressure, raised blood cholesterol, obesity, the sedentary lifestyle can also trigger the cardiac arrest.

Genetics also influences the occurrence of the cardiac arrest, if the coronary artery disease is constant in the family history, then you can have a cardiac arrest. The previous history of the heart attack can also increase the cardiac arrest chances. The incidence of the cardiac arrest is about 2-3 times higher in males than females. Low level of potassium and magnesium can also lead to the cardiac arrest.

6. What are the complications of the Cardiac Arrest?

When the cardiac arrest occurs, the blood supply of the brain is affected more rapidly than the other organs because the brain needs an uninterrupted blood supply constantly. When the blood supply is decreased, you start fainting, which is reflecting that the brain has the diminished blood flow.

The main concern for restoring the heartbeat is to prevent the death of the brain. If the heart rhythm doesn’t restore for more than 10 minutes, then the survival chances will be very low.

7. What are the first aid measures of the cardiac arrest?

If anyone around you is affected from the cardiac arrest, what will be your first measure for saving their life? Initially, you’ll call the ambulance and then start doing the CPR on the patient; it is a technique in which we  maintain the ventilation temporarily. Following method of CPR should be done in the person experiencing the cardiac arrest,

  • Before performing the CPR, ask the person that is he okay? Notice the conscious level of the person, and if he is becoming unconscious then proceed towards the CPR.

  • Check the pulse rate of him and then give the chest compression from your Palmer surface of the hands for about 100 times a minute until the paramedics arrive on the spot.

8. Only trained individuals are allowed to do the CPR?

No! If you’re a bystander then you should begin the CPR after confirming that the person has suffered rather from the heart attack or the cardiac arrest. Though, your priority should be to seek the medical help as early as possible but for the short term preservation of the heartbeat, you should perform the CPR.

If the medical professional is around you, then assist him with the CPR but if you’re alone there, then don’t hesitate to take this step.

9. What is the difference between the cardiac arrest and heart attack?

Both these conditions are not same; however, their presenting complaints are same. Although, the cardiac arrest may be due to the heart attack but the heart attack is caused by the sudden blood flow blockage in the specific area of the heart and the cardiac arrest occurs due to the short-circuit in the electrical system of the heart.

In heart attack, the particular blood vessel is blocked, due to which the muscles are damaged of the heart, but overall, the organs receive the blood supply consistently. When the person is suffering from the heart attack, his consciousness and breathing will be intact but in cardiac arrest, the person will be unconscious.

The symptoms of the heart attack are pain in arms, neck, jaw and arms, discomfort, stomach pain, sweating and shortness of breathing. You should start performing the CPR after calling for the medical help.

10. Instead of CPR, what is the other method?

AED (automated external defibrillator) is usually used on-site by the paramedics, if you don’t know how to deal with the AED then opt for the CPR because it is not too complicated method as compared to the AED. This device is usually available in the first aid box of the gyms or offices to restore the heart beats in the case of an emergency.

11. Can cardiac arrest occur in younger adults and kids?

In young athletes, the cardiac arrest is the main cause of the death during the playing time. Ventricular fibrillation (uncoordinated contraction of the muscles of the ventricles) usually occurs in the athletes, leading to the cardiac arrest.

Hypertrophic cardiomyopathy is the condition in which the myocardium of the heart becomes too thick that’s why, the heart needs more effort to pump the blood and it give rise to the cardiac arrest.

But if the cardiac arrest is occurring in the children then it may be due to the congenital abnormalities, airway and breathing problems and sudden infant death syndrome (SIDS).

12. How can we prevent the sudden cardiac arrest?

Prevention is far much better than cure; if you take out some preventive measures then you can decrease the risk of the sudden cardiac arrest. Like, if you’ve a strong tendency of developing heart disease due to the genetics, then you should avoid the factors that can trigger the cardiac arrest. Here are some measures which everyone should implement in their lives to stay away from the cardiac arrest,

 

  • Stop the smoking because it can reduce the elasticity of your lungs and indirectly affects the heart.

  • Regular checkups and follow up examination can also detect any abnormality of the heart in the early stages, so that it can be treated immediately.

  • Improve your diet and increase the uptake of the potassium and magnesium in your diet like to eat the bananas, yogurt and green leafy vegetables.

  • Keep your exercise in routine and stay physically active, the greater would be your cardiovascular fitness, lessen will be the risk of the cardiac arrest.

  • Reduce the weight if you’re obese.

  • Don’t ignore the frequent chest pain, maybe it is indicating that something is going wrong with the heart.

Well, the risk of the sudden cardiac death can be reduced, if you opt for the lifestyle modification. If you had suffered from the sudden cardiac death and recovered from this, then share your story with us.
