Understanding Cardiac Arrest: Causes, Symptoms, And Life-Saving Actions

Cardiac arrest is a serious and sudden medical emergency. It happens when the heart unexpectedly stops beating. This condition cuts off blood flow to the brain and other vital organs, and without quick treatment, it can lead to death within minutes.

Even though the term might sound scary, the good news is that understanding cardiac arrest can help you act quickly and potentially save a life. In this blog, we’ll explore what cardiac arrest is, why it happens, the warning signs, and how to respond if it ever occurs.

What Is Cardiac Arrest?

Cardiac arrest is when the heart stops pumping blood throughout the body. This is usually due to a problem with the heart's electrical system. Without a regular heartbeat, the brain, lungs, and other organs don’t get the oxygen they need, which can cause a person to collapse and become unresponsive.

It's important to know that cardiac arrest is not the same as a heart attack. A heart attack happens when blood flow to a part of the heart is blocked. Cardiac arrest, on the other hand, is when the heart suddenly stops beating altogether. A heart attack can sometimes lead to cardiac arrest, but the two are different conditions.

What Causes Cardiac Arrest?

Cardiac arrest can be caused by several different factors, including heart-related and non-heart-related issues. The most common causes include:

1. Abnormal Heart Rhythms (Arrhythmias)

The most common cause of cardiac arrest is an arrhythmia called ventricular fibrillation. This happens when the heart beats in a fast and irregular way, preventing it from pumping blood properly.

2. Heart Attack

A heart attack can damage the heart's electrical system and trigger cardiac arrest. If the heart muscle is injured, it may not beat correctly.

3. Heart Disease

People with coronary artery disease, heart failure, or cardiomyopathy (disease of the heart muscle) are more likely to experience cardiac arrest.

4. Congenital Heart Conditions

Some people are born with heart abnormalities that increase the risk of cardiac arrest, especially in young athletes.

5. Drug Overdose or Substance Abuse

Illegal drugs like cocaine or meth, or even certain prescription medications, can interfere with the heart’s rhythm and lead to cardiac arrest.

6. Severe Blood Loss or Oxygen Shortage

Situations such as drowning, choking, or serious injury can reduce oxygen levels in the body, causing the heart to stop.

Who Is at Risk?

Cardiac arrest can happen to anyone, but some people have a higher risk than others. Risk factors include:

History of heart disease or previous heart attack
High blood pressure or high cholesterol
Diabetes
Smoking
Obesity
Sedentary lifestyle
Family history of sudden cardiac arrest
Use of recreational drugs

Even athletes and young people can suffer from cardiac arrest, especially if they have an undiagnosed heart condition. That’s why regular health checkups are essential.

Signs and Symptoms of Cardiac Arrest

Cardiac arrest usually happens suddenly and without warning. A person may:

Collapse without any reason
Lose consciousness immediately
Stop breathing or gasp for air
Have no pulse

Sometimes, a person may have warning signs just minutes before cardiac arrest, such as:

Chest discomfort
Rapid or irregular heartbeat
Dizziness or fainting
Shortness of breath

If you notice any of these symptoms, especially in someone with heart disease, take it seriously and seek medical help.

What to Do in Case of Cardiac Arrest?

When cardiac arrest happens, every second counts. Here’s what you need to do immediately:

1. Call Emergency Services

Call your local emergency number right away (e.g., 911). Tell them it's a suspected cardiac arrest so they send help quickly.

2. Start CPR

Begin chest compressions immediately. Push hard and fast in the center of the chest (about 2 inches deep) at a rate of 100 to 120 compressions per minute. If you're trained, you can also give rescue breaths.

3. Use an AED

An Automated External Defibrillator (AED) is a device that can help restart the heart. If one is available nearby, use it as soon as possible. AEDs are designed to be simple to use, even for people without medical training.

The combination of CPR and an AED can greatly increase the chance of survival until professional help arrives.

How Is Cardiac Arrest Treated?

Emergency responders may use advanced tools and medications to stabilize the heart. After arriving at the hospital, doctors may:

Run tests to find the cause of the arrest
Use defibrillation again if needed
Provide medications to support heart function
Implant a device called an ICD (Implantable Cardioverter Defibrillator) in people at high risk to prevent future arrests

Ongoing care may also involve lifestyle changes, medications, and treating underlying conditions like high blood pressure or arrhythmias.

Can Cardiac Arrest Be Prevented?

Yes, in many cases, cardiac arrest can be prevented by leading a heart-healthy lifestyle and managing medical conditions early. Here’s how:

Exercise regularly
Eat a heart-healthy diet rich in vegetables, fruits, lean proteins, and whole grains
Avoid smoking and excessive alcohol
Keep your blood pressure, cholesterol, and blood sugar under control
Manage stress through mindfulness, meditation, or hobbies
Get regular check-ups, especially if you have a family history of heart issues

If you’ve already had a heart attack or have known heart problems, your doctor might recommend medications or devices like an ICD to reduce your risk of cardiac arrest.

Why CPR and AED Training Matter

Every minute without CPR reduces a cardiac arrest victim’s chance of survival. If more people knew how to perform CPR and use an AED, many lives could be saved every year.

Consider taking a CPR training course in your community. It’s a small investment of time that can make a huge difference in someone’s life—even a stranger's.

Conclusion

Cardiac arrest is a sudden and life-threatening condition that can affect anyone, regardless of age or health. Recognizing the warning signs, understanding the risk factors, and knowing how to respond with CPR or an AED can mean the difference between life and death. While it’s a frightening topic, being informed and prepared can help you protect yourself and your loved ones.

Virtual Cooking Class with a Dietitian: Why It’s a Powerful Corporate Wellness Benefit

Corporate wellness programs in India are undergoing a meaningful transformation. What once revolved primarily around annual health checkups and gym memberships is now shifting toward sustainable lifestyle-based interventions. Among these, the virtual cooking class with a dietitian has emerged as one of the most practical and high-impact wellness initiatives for modern workplaces.

Poor dietary habits are a leading contributor to lifestyle-related conditions such as diabetes, obesity, hypertension, and heart disease. According to the Indian Council of Medical Research (ICMR) and the National Family Health Survey (NFHS-5), a significant proportion of India’s working population consumes excess refined carbohydrates, sugar, and unhealthy fats, while falling short on protein, fibre, and essential micronutrients.

For corporate wellness initiatives to create lasting impact, they must move beyond awareness and actively support behaviour change. Dietitian-led virtual cooking classes address this gap by turning nutritional knowledge into daily practice.

Why Nutrition Is a Critical Corporate Wellness Priority

1. Rising lifestyle disease burden among employees
