Sudden Cardiac Arrest: What are its causes and how to stay protected?

Cardiac Arrest Causes

Sudden cardiac arrests are usually caused by ventricular fibrillation. It is a form of arrhythmia where the heart stops pumping blood within the body. It can be really fatal and if the patient is not treated within minutes of a cardiac arrest, then he/she might lose their life. The 1st and foremost thing that is important to understand are the causes that could lead to this problem. Some of the common conditions that are essentially the reason behind it have been mentioned below:

Cardiac Arrest Causes

  • Enlarged heart: It is a condition where the muscular walls of the heart starts thickening and becomes abnormally large. This condition makes it really difficult for the heart to pump blood and it leads to arrhythmias.
  • Coronary artery disease: This is the most common reason behind a sudden cardiac arrest. When the arteries get blocked due to deposits and they are clogged with cholesterol, it becomes really difficult for the heart to pump blood smoothly. In this condition, the heart is not able to conduct electrical impulses and hence the blood flow decreases.
  • Congenital disease: A particular segment of individuals face congenital heart defects since birth. It is important to go through a corrective surgery at an early age to avoid any kind of heart problems. If this disease is not treated at an early stages, it can increase the chances of sudden cardiac arrest even in children.
  • Valvular disease: The chambers of heart valve play an important role in making sure that the blood flows smoothly. If they become narrow or there is any kind of leakage in the heart valves, then the stress caused by the leaking valve increases the risk of arrhythmia.

Immediate measures required in cases of sudden Cardiac Arrests

Besides knowing the possible reasons behind a sudden cardiac arrest, it is important to stay well-aware of the best possible measures if such a case arises. Some of the most common measures that can essentially save a person from succumbing to the attack are as follows:

  • Perform CPR: The first and foremost step is to check if the person is breathing normally. If you see any abnormal breathing pattern, then one needs to initiate the cardiopulmonary resuscitation process. Push hard on the patient’s chest and the rate of compression should be around episode free gems 100 to 120 per minute. In case, you have someone around you who has been trained in CPR then ask them to check the patient’s airway. You should also give rescue breaths to the patient after every 30 compressions.
  • Call a nearby hospital: You should call any local hospital and make sure that the patient gets treatment as fast as possible. Once the patient starts breathing properly, shift him/her to any other hospital of your choice. The doctor in a local hospital will make sure that the chest compressions are responsive.
  • Using portable defibrillator: A person who have undergone the basic training in medical sciences will be aware of defibrillators. Having this device can deliver shock waves to improve the CPR rate of the patient. It can be really helpful to prompt the patient gain consciousness.


When a person suffers from a sudden cardiac arrest, the brain tends to be the first part of the body to stop functioning. The brain does not have any reserve oxygen-rich blood and this leads to unconsciousness. It is important to make sure that the heart keeps pumping the blood in a normal rhythm to ensure that there is no damage in the brain.
