The issue of sportsmen or women collapsing on the pitch of play suddenly which sometimes can lead to death have been ascribed to cardiac arrest, this stops the heart from pumping and prevents blood from flowing to the brain.

Speaking to ECHONEWS, renowned medical practitioner, Doctor Kolade Kolapo who works in the General Outpatient Department (GOPD) of Codic specialist medical center described Cardiac arrest as a medical emergency that occurs unexpectedly.

Doctor Kolade Kolapo added that the main cause of cardiac arrest is ventricular fibrillation or ventricular tachycardia.

“Cardiac arrest occurs when the heart suddenly and unexpectedly stops pumping. If this happens, blood stops flowing to the brain and other vital organs. Cardiac arrests are caused by certain types of arrhythmias that prevent the heart from pumping blood.

“Cardiac arrest is a medical emergency. Nine out of 10 people who have a cardiac arrest outside of a hospital often dies within minutes.

“A person may be having a cardiac arrest if they,

“Collapse suddenly and lose consciousness (pass out)

Are not breathing or their breathing is ineffective or they are gasping for air

Do not respond to shouting or shaking

Do not have a pulse

The main cause of cardiac arrest is ventricular fibrillation or ventricular tachycardia, which are types of arrhythmias. Important risk factors include prior cardiac arrest, coronary heart disease, heart valve disease, congenital heart defects, and arrhythmias caused by faulty genes. However, half of cardiac arrests happen to people who did not know they had a heart problem.

“Cardiac arrest is a common cause of death.

“Cardiac arrest causes about half of the deaths linked with heart attack and stroke.

Calling Medical Emergency team with immediate treatment with cardiopulmonary resuscitation (CPR) and defibrillation can save the life of a person in cardiac arrest. A defibrillator is a device that sends an electric shock to the heart to try to restore its normal rhythm. Most people who have a cardiac arrest do not receive treatment quickly enough to survive.

“Automatic external defibrillators (AEDs)

Automated external defibrillators (AEDs) are a type of portable defibrillator installed in places where people gather, such as stadiums, bus and train stations, schools, and offices. Like cardiopulmonary resuscitation (CPR)external link, AEDs offer a way for bystanders to provide treatment until first responders arrive.

“When a person has a cardiac arrest, bystanders seek for healthcare provide CPR, and use an AED. A person has a better chance of surviving when first responders arrive quickly,

“Everyone has a role in recognizing the signs of cardiac arrest and taking action to save lives.

Know where to find AEDs. AEDs are in many public places, including offices, schools, shopping malls, grocery stores, airports, event venues, and gyms. Check to see whether your office or school has an AED.
