Reasons for the occurrence of a cardiac arrest

A cardiac arrest is a medical condition in which the heart stops pumping blood to the rest of the body. Cardiac arrests can lead to sudden deaths if not treated immediately. As discussed further in this article, several situations can end up in cardiac arrests, where Heartsine defibrillators can help. Heartsine is a trusted brand of defibrillators in Australia that has all the requisite certifications for medical use, and that too at reasonable prices. Despite having the best-in-class option for an emergency, most of these emergencies can be avoided in the first place through certain precautions.

Pre-existing heart conditions

The average age for cardiac arrest is older than for most other conditions. Cardiac arrest can occur in people with an already existing heart condition such as heart attack (myocardial infarction), heart failure and congenital disabilities such as tetralogy of Fallot, tricuspid atresia and hypoplastic left heart syndrome.

Pursuant activity

The activity at the time of the arrest is also a contributing factor that leads to the possibility of a cardiac arrest. In case anyone is experiencing any of the following symptoms, they are at a higher risk for Sudden Cardiac Arrest (SCA) attack:

  • Strenuous activity or exercise
  • Physical exertion that accelerates heart rate
  • Excessive alcohol consumption and smoking
  • Caffeine overdose

Arrhythmic history

An arrhythmia points to a problem with the heart’s electrical system. It may cause the heart to beat faster, slower, or with an abnormal rhythm. Arrhythmias can occur at any age and are often caused by a problem with the structure or function of your heart muscle (cardiomyopathy). Still, they may also be triggered by other conditions such as high BP or thyroid disease. Some arrhythmias may not need treatment if assisted timely by Heartsine defibrillators, while others may require medication or surgery to treat them.

Mental or physical shock triggers

Cardiac arrest can be caused by trauma. This can be physical or mental, but it’s most often a sudden shock or long-term stress that causes the heart to stop beating. Life-threatening conditions may erupt shocks when your body cannot get enough oxygen, blood or glucose to tissues and organs. Physical trauma may include a car accident, fall, gunshot wound or attack. Mental trauma involves experiencing a sudden loss of a loved one and experiencing shock from an unexpected event such as seeing someone else injured.

Signs and symptoms of shock include:

  • Cold, clammy skin
  • Weak pulse or no pulse
  • Dizziness or fainting (loss of consciousness) due to low blood pressure caused by bleeding into the skin and body cavities such as the chest cavity (hemothorax) and abdomen (abdominal haemorrhage)

Routine habits

Lack of exercise, lack of sleep and stress are all habits that can contribute to a cardiac arrest. These factors can also lead to other conditions such as hypertension and heart failure. Smoking is one of the most common reasons for experiencing a heart attack or stroke. Smoking cigarettes has been shown to increase the likelihood of getting cancer by at least 30%. Smokers have higher chances of stroke (30% higher), developing lung cancer (25 times more likely, and chronic obstructive pulmonary disease (150 times more likely) than people who do not smoke. Other habits that should be avoided include alcohol abuse, drug abuse and obesity because they can cause health issues like coronary artery disease, which could lead to cardiac arrest if left untreated.


Cardiac arrest can be caused by various factors, such as a heart condition or an underlying medical condition. It can also occur when the body is exposed to extreme conditions like high heat, cold water immersion and shock waves. The best way to prevent cardiac arrests is to avoid being in panic by regulating breathing regularly through practices such as meditation.
