heartbeat

Compared meaning: the beating of the heart (noun).

比较义项：心脏的搏动／脉搏（名词）。

• pulse

  Refers to the rhythmic throb of blood in the arteries, usually felt by pressing on the wrist or neck; common in phrases like 'take/check someone's pulse.'

  指按压手腕或颈部所感觉到的动脉搏动，常用于「把脉」「量脉搏」等说法，强调用手指触摸检测。

  The paramedic pressed two fingers to his wrist to check his pulse.

  急救人员把两根手指按在他的手腕上，检查他的脉搏。

• heartbeat 本词

  Refers to a single beat of the heart itself, often heard through a stethoscope or felt against the chest; used in phrases like 'listen to/feel a heartbeat.'

  指心脏本身跳动的一次搏动，常通过听诊器听到或贴近胸口感觉到，用于「听心跳」「感觉心跳」等说法。

  She pressed her ear to his chest and listened to his heartbeat.

  她把耳朵贴在他的胸口，听他的心跳。

Pulse and heartbeat both mean the heart beating, but differ. Pulse is blood felt in arteries, as in 'take a pulse'. Heartbeat is one beat of the heart, heard through a stethoscope. Not compared: pulse's senses 'beans' and 'signal pulse', and heartbeat's 'short moment' sense.

这两个词在此义项上很接近，都指心脏的搏动，但语体和搭配不同：pulse强调用手指触摸到的动脉搏动，常见于「把脉」「测脉搏」；heartbeat强调心脏本身跳动发出的声音或动作，常见于「听心跳」。这里不比较pulse表示「豆类（如豆子、扁豆）」或「（光、声、电等的）脉冲信号」的义项，也不比较heartbeat表示「转瞬之间」的比喻义。
