According to doctors, cardiac arrest comes with no advance signal. This cardiac arrest can occur if the heart rate starts becoming irregular. The heart rate can stop after cardiac arrest.

Once a patient's artery is blocked, oxygenated blood reaches the heart. Only then is heart attack. If the treatment does not start immediately, that part of the heart becomes ineffective.

Mukesh Goyal, senior consultant and cardiologist at Apollo Hospital in India, said that all heart attacks are not passed on cardiac arrest.

Only five to ten percent of the cases become cardiac arrest after a heart attack. If a heart attack is stopped in large numbers after heart attack, then cardiac arrest is only done.
