What indicates "Heartbeats" in terms of life evidence?

The concept of "Heartbeats" as it relates to evidence of life signifies a continuous and regular rhythm indicative of healthy cardiac function. This steady rhythmic contraction is a vital sign that typically implies an ongoing physiological process of life, where the heart is actively pumping blood throughout the body. In medical and legal contexts, the presence of such a rhythm helps to establish the viability of an individual and supports the determination of whether life is present.

On the other hand, while detectable muscle movement or transient cardiac contractions may suggest some activity, they do not necessarily confirm the consistent functionality of the heart. Likewise, evidence within 24 hours after birth may reflect certain states of life but does not define the consistent heartbeat as a marker of ongoing life. Therefore, the continuous and regular rhythm of heartbeats is the definitive indicator of life evidence in this framework.
