Veteran actor Nana Patekar died on Thursday morning at age 75 after suffering a severe cardiac arrest at his Goa residence and was brought dead to Manipal Hospital.
Cardiologists explain that a cardiac arrest involves the heart abruptly stopping effective beating due to an electrical malfunction, differing from a heart attack caused by blood flow blockage.
Medical experts emphasize immediate bystander cardiopulmonary resuscitation and defibrillator use as vital emergency steps to manually circulate blood and double or triple survival chances.
