Why is having a lower pulse or higher stroke volume good for a person?

A lower pulse, often indicative of a more efficient heart, means that the heart can pump an adequate amount of blood with fewer beats, which can reduce wear and tear on the cardiovascular system. A higher stroke volume signifies that the heart ejects a larger volume of blood with each contraction, improving oxygen delivery to tissues and enhancing overall physical endurance. Together, these factors can indicate better cardiovascular fitness, lower stress on the heart, and a reduced risk of heart-related diseases.
