心拍

1. Origins, structure, and basic meaning

• Structure: 心拍 (しんぱく) is a noun for a heartbeat or the rate at which the heart beats.
• Basic usage: It appears when recording heart rate around exercise or checking changes in heartbeat with a device.
  • 運動前後の心拍を記録した。 — We recorded heart rate before and after exercise.
  • 腕の機器で心拍の変化を確認した。 — The wrist device showed changes in the heartbeat.
