Sudden cardiac arrest #bestcardiologistinperambur #bestdiabetologistinkolathur

Sudden cardiac arrest (SCA) is a life threatening medical emergency where the heart unexpectedly stops beating due to electrical malfunction halting blood flow to the brain and organs .It causes immediate collapse, loss of consciousness, and lack of pulse. Without immediate CPR and defibrillation, it leads to death within minutes

Key Aspects of Sudden Cardiac Arrest:
  • What Happens: The heart's electrical system malfunctions, causing it to quiver or stop, rather than pumping properly.
  • Symptoms: Sudden collapse, unresponsiveness, and abnormal/no breathing (gasping).
  • Causes: Often triggered by arrhythmia (irregular heart rhythm), such as ventricular fibrillation, or structural heart issues.
  • Heart Attack vs. Cardiac Arrest: A heart attack is a "circulation" problem (blockage), while cardiac arrest is an "electrical" problem. A heart attack can cause cardiac arrest.
  • Survival: Immediate action is critical. Survival rates double or triple if bystanders perform CPR immediately and use an Automated External Defibrillator
Warning Signs (Often Sudden):
While often occurring without warning, symptoms can include racing heart, dizziness, lightheadedness, chest pain, or shortness of breath
