What is Cardiac Arrest?
Cardiac arrest is the sudden and complete loss of heart function, causing the heart to stop pumping blood effectively to the brain, lungs, and other organs, resulting in immediate loss of consciousness and absence of normal breathing. It is distinct from a heart attack, which involves blocked blood flow to the heart muscle itself, though a heart attack can trigger the abnormal heart rhythms that lead to cardiac arrest. Without immediate intervention through cardiopulmonary resuscitation and defibrillation, cardiac arrest is fatal within minutes, as brain damage begins within four to six minutes of the heart stopping. Survival rates depend heavily on how quickly bystander CPR and defibrillation are started, making public awareness and access to automated external defibrillators critically important.

Causes of Cardiac Arrest
Cardiac arrest most commonly results from an abnormal, chaotic heart rhythm called ventricular fibrillation, which prevents the heart from pumping blood effectively, often triggered by an acute heart attack or underlying coronary artery disease. Other causes include severe electrolyte imbalances, certain inherited heart rhythm disorders, drug overdose, severe trauma, drowning, and electrocution. Structural heart conditions such as cardiomyopathy and heart failure also significantly increase the risk of sudden cardiac arrest.
Symptoms of Cardiac Arrest
sudden collapse, loss of consciousness, absence of normal breathing or only gasping breaths, no detectable pulse, chest pain, shortness of breath, palpitations, or dizziness sometimes occurring in the moments before collapse
Treatment & Types of Cardiac Arrest in Telangana
Immediate cardiopulmonary resuscitation, involving chest compressions and rescue breaths, is essential to maintain some blood flow to vital organs until definitive treatment can be provided. Defibrillation, delivering an electric shock to the heart using an automated external defibrillator, is used to restore a normal heart rhythm when the underlying rhythm is shockable. Following successful resuscitation, patients require intensive care, treatment of the underlying cause such as a blocked coronary artery, and sometimes implantation of a defibrillator device to prevent future episodes.
Cardiac arrest is classified by the underlying heart rhythm found at the time of collapse — shockable rhythms such as ventricular fibrillation or pulseless ventricular tachycardia, which respond to defibrillation, versus non-shockable rhythms such as asystole (no electrical activity) or pulseless electrical activity, which require different resuscitation approaches focused on treating the underlying cause.

Frequently Asked Questions
Is cardiac arrest the same as a heart attack?
No, a heart attack is caused by a blocked artery reducing blood flow to heart muscle, while cardiac arrest is the sudden, complete stopping of the heart's pumping function — a heart attack can trigger cardiac arrest, but they are distinct events.
How quickly does CPR need to start to make a difference?
Brain damage can begin within four to six minutes of the heart stopping, so starting CPR immediately, even before paramedics arrive, significantly improves survival chances.
Can someone survive cardiac arrest outside a hospital?
Yes, survival is strongly linked to how quickly bystander CPR and defibrillation with an automated external defibrillator are started.
Will I need a defibrillator device implanted after surviving cardiac arrest?
Many survivors, particularly those with an underlying heart condition or shockable rhythm, are considered for an implantable defibrillator to prevent future episodes.
What increases my personal risk of cardiac arrest?
Underlying coronary artery disease, cardiomyopathy, inherited heart rhythm disorders, and poorly controlled cardiovascular risk factors like high blood pressure or diabetes all raise risk.
