Symptoms Causes and Treatment of Cardiac Arrest

Symptoms Causes and Treatment of Cardiac Arrest

Aug 03, 2021

A sudden cardiac arrest refers to a sudden loss of heart function, which causes loss of breathing and consciousness. The condition results from problems with the heart’s electrical system, disrupting its pumping action and stopping blood flow in the body. In this case, you need to get emergency treatment of cardiac arrest immediately.

Note that it’s electrical impulses that control your heartbeat, and when the pattern changes, you get an irregular heartbeat, also called arrhythmia. There are slow and rapid arrhythmias. When the heart rhythm stops, then you get a cardiac arrest.

A cardiac arrest is different from a heart attack, which occurs when there is a blood flow block in some part of the body. Still, heart attacks sometimes trigger electrical disturbances that can cause a sudden cardiac arrest.

If not immediately treated, a cardiac arrest can cause sudden death. However, with fast and appropriate treatment at an emergency room in Waxahachie, survival is possible. Cardiopulmonary resuscitation (CPR) via a defibrillator or chest compressions can increase survival chances before support arrives.

Cardiac Arrest Signs and Symptoms

Mostly, the cardiac arrest comes unannounced. However, some people get warning signs imminent to a cardiac arrest. They include:

  • Chest pains
  • Dizziness
  • Palpitations
  • Fainting
  • Breathlessness
  • No pulse

After a cardiac arrest, you may be:

  • Unconscious
  • Unresponsive
  • Not Breathing

Causes of Cardiac Arrest

Many factors can cause a cardiac arrest, but there are two leading causes, as follows:

  • Ventricular Fibrillation

Your heart has four chambers, two of which are ventricles. In ventricular fibrillation, these ventricles shudder out of control and dramatically change the heart rhythm. They begin to pump inefficiently, severely decreasing the amount of blood flowing through the body. In some cases, this circulation completely stops and can cause sudden cardiac arrest.

  • Atrial Fibrillation

This is an arrhythmia of the upper chambers, atria. Atrial fibrillation is an effect of the sinoatrial (SA) node not sending out the right electric impulses. The SA node in the right atrium regulates the speed of pumping blood.

Atrial fibrillation of the electrical impulse hinders the ventricles’ ability to pump blood out efficiently. Cardiology in Waxahachie, TX, can reverse the imminence of atrial fibrillation.

Risk Factors for Cardiac Arrest

Some heart conditions can increase the risk of getting a cardiac arrest, including:

  • Coronary heart disease

This heart disorder originates from the coronary arteries that supply blood directly to the heart muscles. If they are blocked, the heart stops working completely.

  • Large Heart

An abnormally large heart increases your risk of suffering a cardiac arrest. A large heart beats irregularly and may be highly prone to damage.

  • Irregular heart valves

Valve diseases narrow or causes the heart valve to leak. Therefore, blood circulation either overloads the heart chambers or does not sufficiently fill them with blood. With time they become weak.

  • Congenital Heart Disease

It’s a congenital heart disease that most people are born with. Sudden cardiac arrests can occur among children born with severe heart problems.

  • Electrical impulse problems

The risk of suffering cardiac sudden death increase among people with heart electrical system problems. They are called primary heart rhythm abnormalities.

Other risk factors include smoking, obesity, substance abuse, previous heart attack risk, high blood pressure, and the male gender.


CPR is the most common emergency treatment for cardiac arrest. Another is defibrillation, both of which get your heart beating after it stopped. The doctors try to stabilize your condition at the ER near you to treat a probable heart attack, heart failure, or an electrical imbalance.

Other ways to minimize the risk of an attack include:

  • Medication – lowers blood pressure and cholesterol
  • Surgery – repairs blood vessels and valves
  • Exercise – improves your cardiovascular fitness
  • Dietary changes – helps to lower cholesterol levels.

Cardiac Arrest vs. Heart Attack

Cardiac arrest and cardiac attack are two disparate cardiac events. A cardiac arrest is when blood pumping by the heart stops, breathing stops, and you lose consciousness.

In a heart attack, there’s blockage of a coronary artery, preventing blood flow to specific parts of the heart muscle. The victim remains conscious, and breathing doesn’t stop.

Hear attacks severally lead to cardiac arrests because, in the process, the heart might develop a risky rhythm that leads to a cardiac arrest. Heart attack and cardiac arrest are all emergencies that require emergency cardiology services in Waxahachie, TX.
