Cardiac Arrest Part 1 | Definition, Pathophysiology, Causes, Chain of Survival, BLS & ALS Explained

Cardiac Arrest Part 1 provides a complete conceptual and clinical understanding of this life-threatening emergency.
In this lecture, we cover:

Definition and difference between cardiac arrest and heart attack

Pathophysiology: electrical and mechanical failure of the heart

Etiology and reversible causes (H’s and T’s)

The Chain of Survival and its importance in improving survival rates

Basic Life Support (BLS): steps, CPR technique, and AED use

Advanced Life Support (ALS): airway, drugs, defibrillation

Perfect for medical students, residents, paramedics, and healthcare professionals preparing for exams or clinical practice.

👉 Don’t miss Part 2, which will include post-resuscitation care, post-arrest management and outcomes(neurological prognostification),key diferences in peediatric and adult CPR etc
