Srimad-Bhagavatam

SB Canto 4

As soon as the circulation of blood and air within the body stops, it is to be understood that the soul within the body has left. The stoppage of the blood's circulation is perceived when the hands and feet lose heat. One tests whether a body is alive or not by feeling the heart's palpitations and the coldness of the feet and hands.
