Over the past few years, a worrying trend has emerged across India. Cases of sudden cardiac arrest among young adults, sometimes even people in their 20s and 30s, are being reported more frequently. Stories of seemingly healthy individuals collapsing during workouts, sports activities, or even routine daily tasks have left many families shocked and confused. While heart disease was once largely associated with older adults, modern lifestyles are changing that reality.          Cardiac arrest occurs when the heart suddenly stops pumping blood effectively, causing loss of consciousness and, if untreated, death within minutes. It is different from a heart attack, which usually happens due to blocked arteries. However, heart attacks can sometimes lead to cardiac arrest.
