Cardiac Arrest Symptoms

The signs and symptoms of cardiac arrest are very clear: 

  • Loss of consciousness
  • Unresponsiveness
  • Collapse
  • Chest pain
  • Absence of a pulse

Causes of Cardiac Arrest

A common cause of cardiac arrest is an arrhythmia called ventricular fibrillation. This occurs when the large chambers of the heart (the ventricles) stop beating rhythmically. Without a strong contraction by the ventricles, oxygen-rich blood cannot reach the tissues — including the brain and the heart. The heart will eventually stop beating. Ventricular tachycardia, which occurs when the heart beats too fast to sustain a rhythm, also can cause cardiac arrest.

Signs and symptoms of an arrhythmia that can precede cardiac arrest include:

  • Heart palpitations or an irregular heartbeat
  • Rapid or erratic pulse
  • Feeling like your heart is pounding
  • Unusually slow pulse (fewer than 60 beats per minute)
  • Shortness of breath
  • Feeling dizzy, woozy, or lightheaded
  • Fainting

Arrhythmias that induce cardiac arrest can be caused by a variety of factors including:

  • Cardiomegaly (enlarged heart) due to such conditions as heart failure, high blood pressure, or heart valve disease
  • Electrical abnormalities, such as Long QT Syndrome or Wolff-Parkinson-White Syndrome
  • Prior heart attack or heart surgery that causes scarring of the cardiac tissue
  • Drug abuse
  • Side effect of medications used to correct an abnormal heart rhythm
  • Severe dehydration or severe electrolyte imbalances

Treatment & Prevention of Cardiac Arrest

The treatment and prevention of cardiac arrest depends on the cause. Someone in cardiac arrest may survive with immediate treatment. 

Treatment of cardiac arrest includes:

  • Calling 911 for emergency medical responders
  • Using an automated external defibrillator (AED), if available
  • Initiating cardiopulmonary resuscitation (CPR)

To prevent possible cardiac arrest, you should:

  • Treat and monitor any known heart condition
  • Treat and monitor any known electrical abnormalities of your heart
  • Refrain from illicit drugs
  • Discuss with your doctor the potential side effects of any medication you take to correct a heart rhythm problem
  • Engage in a heart-healthy lifestyle
  • Obtain a heart examination before competing in sports activities
