今回のモデルさんは魅力的なタトゥーが入ったmahoさんです。普段はショーモデルをやっている彼女はスタイルも抜群です。

通常時から90BPMと他の方に比べると少し速い心拍で、仰向けで寝ているシーンなどはリラックスしているようで緊張しているのか鼓動が大きくなっていきます。

また心臓の拍動が一時的に乱れて「ドクン」と強く打つことでギュッとするような不整脈のようなものも見られます。

Here's the English version:

This time, our model is maho, who has striking tattoos. She normally works as a runway/show model and has a stunning figure.
Even at rest, her heart rate sits around 90 BPM—a little faster than most people. In scenes such as lying on her back, she appears relaxed, yet perhaps from nervousness, her heartbeat gradually grows stronger. You can also hear moments where her rhythm briefly breaks into a strong "thump," an arrhythmia-like beat that gives a tight, clenching sensation.

Heart sounds while relaxing on the bed
Heart sounds while lying on her back (supine)
Breathing and heart sounds during sleep
Heart sounds as she rolls over / shifts position
Heart sounds as she sits up
Heart sounds and heart-rate changes when her chest is compressed
Heart sounds and heart rate while holding her breath to the limit
Heart sounds and heart-rate changes as she exhales
Changes while taking deep breaths
Heart sounds as her breathing settles

A couple of word-choice notes: I used "supine" in parentheses since it's the precise term, but "lying on her back" reads more naturally for a general audience—drop one if you prefer. For arrhythmia-like, I went with "arrhythmia-like" rather than "arrhythmia" to keep it descriptive rather than implying an actual medical condition. Let me know if you'd like a softer/more sensory tone or a more clinical one.
