Signs of Cardiac Arrest and Immediate Actions
Cardiac Arrest:
This is primarily an electrical problem where the heart
suddenly stops beating effectively or develops a dangerously fast and
disorganized rhythm, preventing it from pumping blood.
Life-Threatening Emergency: Without immediate treatment, death can occur within minutes.
Immediate Treatment: Cardiopulmonary Resuscitation (CPR) and defibrillation (an electric shock) are critical.
Signs of Cardiac Arrest:
Sudden collapse and unresponsiveness
No pulse
No breathing (or irregular, abnormal gasping breaths, sometimes called “agonal breathing”)
Possible twitching or seizure-like activity (which can be mistaken for a seizure)
Prior to collapse, individuals might experience symptoms such as
chest pain, nausea, shortness of breath, palpitations, dizziness, or
weakness.
Causes of Cardiac Arrest:
The most common cause is heart rhythm disorders (arrhythmias),
particularly Ventricular Fibrillation (V-fib), where the heart quivers
instead of pumping.
Risk Factors for Cardiac Arrest:
Family history of cardiac arrest or sudden death
History of heart attack or other heart disease
High blood pressure, high cholesterol, diabetes, obesity, smoking
Immediate Management of Cardiac Arrest:
Cardiopulmonary Resuscitation (CPR)
Actions for a Bystander:
Ensure the scene is safe.
Check for responsiveness and breathing.
Call emergency services immediately (e.g., 911 or your local emergency number).
Begin CPR immediately, performing chest compressions at a rate of 100-120 compressions per minute.
Prevention of Cardiac Arrest:
Managing Risk Factors: Control blood pressure, cholesterol, and
diabetes; quit smoking; maintain a healthy weight; and adopt a
heart-healthy lifestyle.
Preventive Treatments:
Implantable Cardioverter-Defibrillator (ICD)
Catheter-based procedures (e.g., ablation)
Medications (e.g., beta-blockers)
Consistent follow-up care and regular medication adherence are crucial.
Educating others in CPR can save lives.
