The Conservation of Heart

In every heartbeat, a timeless principle is revealed: energy is neither created nor destroyed—it is transformed, conserved, and returned. This idea, which we might call The Conservation of Heart , invites us to explore the poetry of life through numbers, and to imagine, even if only in thought, a system that echoes the heart’s rhythm. The Heart’s Pulse in Numbers Each beat of the human heart is a carefully orchestrated event, where stored chemical energy is transformed into mechanical work. Let’s examine the math that underlies this vital process. Stroke Volume and Pressure Stroke Volume (Vₛ): The average human heart ejects about 70 mL of blood per beat. Converting to cubic meters: V s = 70 mL = 70 × 10 − 6 m 3 Vₛ = 70\,\text{mL} = 70 \times 10^{-6}\,\text{m}^3 Effective Pressure (P): Though the heart experiences a range of pressures, a common approximation for the effective pressure during ejection is around 93 mmHg. Converting to Pascals: 93 mmHg × 133.3 ...
