Abstract: Cardiac arrest is a life-threatening emergency that demands quick action to enhance survival rates. Recognizing the underlying heart rhythm during cardiac arrest via rhythm analysis is essential for planning therapy. Without immediate medical attention, cardiac arrest may have fatal results very fast. To choose the best course of therapy and increase survival rates, quickly identifying the underlying rhythm during cardiac arrest is essential. Patients experiencing cardiac arrest rely heavily on rhythm analysis and direct therapy to determine the underlying heart rhythm. It is essential to know if the patient's underlying rhythm can be shocked before beginning therapy, and rhythm analysis may aid this. Defibrillation is necessary for shockable rhythms like ventricular fibrillation (VF) and ventricular tachycardia (VT). In contrast, CPR and other ALBs are necessary for non-shockable rhythms such as asystole and pulseless electrical activity (PEA). This retrospective study aims to determine how well rhythm analysis predicts survival outcomes for Indian patients who have had cardiac arrests. When the heart stops pumping blood to the body, a medical emergency known as cardiac arrest develops.
