Cardiac Arrest Symptoms: What You Need to Know

In today’s fast-paced world, it’s crucial to be aware of the signs and symptoms of cardiac arrest. This life-threatening condition can strike suddenly and without warning, making it essential for everyone to understand its symptoms. By recognizing the signs early, you could potentially save a life. In this article, we’ll explore the symptoms of cardiac arrest, its causes, and what to do if you or someone else experiences these symptoms.

Understanding Cardiac Arrest:

Cardiac arrest occurs when the heart suddenly stops pumping blood to the body. Without immediate intervention, it can lead to brain damage or death within minutes. Unlike a heart attack, which is caused by a blockage in the coronary arteries, cardiac arrest often occurs due to an electrical malfunction in the heart.

Common Symptoms of Cardiac Arrest:

Sudden Loss of Consciousness: One of the most prominent signs of cardiac arrest is an abrupt loss of consciousness, often without any warning signs.

Absence of Pulse: During cardiac arrest, the heart stops beating, leading to the absence of a pulse. This can be checked by feeling for a pulse on the neck (carotid artery) or the wrist (radial artery).

No Breathing or Abnormal Breathing: In many cases of cardiac arrest, the individual may stop breathing altogether. However, in some instances, abnormal breathing patterns such as gasping or agonal breathing may occur.

Chest Pain or Discomfort: While not always present, some individuals may experience chest pain or discomfort before cardiac arrest occurs. This pain is often described as tightness, pressure, or squeezing in the chest.

Nausea or Vomiting: In some cases, individuals experiencing cardiac arrest may feel nauseous or vomit shortly before losing consciousness.

What to Do in Case of Cardiac Arrest:

If you witness someone experiencing symptoms of cardiac arrest, it’s essential to act quickly. Follow these steps:

Call Emergency Services: Dial your local emergency number immediately to summon professional medical help.

Perform CPR: If you are trained in cardiopulmonary resuscitation (CPR), begin chest compressions and rescue breaths until medical professionals arrive. CPR can help maintain blood flow to vital organs until advanced medical care is available.

Use an Automated External Defibrillator (AED): If an AED is available, follow the device’s instructions to deliver an electric shock to the heart, which can help restore its normal rhythm.

Continue Support: Stay with the individual until emergency responders arrive and provide any necessary assistance or information to the medical team.


Recognizing the symptoms of cardiac arrest and knowing how to respond can make a significant difference in saving lives. By familiarizing yourself with these signs and taking prompt action, you can help improve the chances of survival for someone experiencing cardiac arrest. Remember, quick intervention is key, so don’t hesitate to act if you suspect someone may be in cardiac arrest. Your actions could make all the difference. Stay informed, stay prepared, and be ready to save a life.
