Thank you for viewing.
This is the first heartbeat of Miyu, age 24.
She was a beautiful, serious, and gentle-looking model with healthy, tanned skin and a petite figure (150 cm tall, 43 kg).
Also, her long hair that reaches down to her chest is very lovely, and while I certainly like her bob-style short hairstyles, I'm also drawn to long hair like Miyu's.
Furthermore, she said that she was interested in this photoshoot and agreed to participate, and in the video, she showed interest in the changes in her heartbeat when she took a deep breath and when she saw her own heart on the ultrasound, making her one of the few models who understands this fetish.
While his heart rate was average, the difference in his heart rate when he took a deep breath was easily noticeable, and there were instances where his rhythm was unstable when his chest was compressed, making it easier to discern changes in his rhythm.

That is the case.
The video is 55 minutes and 24 seconds long.
For the self-introduction and heart sound session, participants were asked to place a stethoscope on their own hearts and listen to their own heartbeats.
Miyu, being a quiet person, has an average heart rate of 72 BPM.
There were no signs of arrhythmia, and the rhythm was regular. Also, because the patient was slender, the heart sounds were easy to hear, and I could hear the heart valves beating with each beat.
There were moments when I had to change my posture, and my heart rate seemed to increase slightly during those times.
Miyu, you're the same; even subtle changes in posture can affect your heart rate, right?
In the video, she also answers questions such as, "If your boyfriend had a fetish for the sound of heartbeats, would you let him listen to your heartbeat?" and "Have you had a heart-pounding experience recently?" As for the heart-pounding experience, as anyone who has experienced it will know, it was a truly heart-pounding moment. I'm sure even Miyu's average heart rate was about to jump out of her chest at that moment!
Next, they used a stethoscope to hear their own heartbeat for the first time.
Her reaction was, "My heart is beating so loudly, I don't like it!" That's just proof that Miyu's heart is in good health, isn't it?
If her heartbeat, which is so loud it's almost deafening, were to quiet down, Miyu wouldn't be able to survive, so I hope it continues to beat strongly like this for a long time.
After listening to their own heartbeats for a while, they were asked to feel their pulse by placing their hands on their chest and carotid arteries, and their heart rate was checked with a pulse oximeter.
When I checked, it was below 70 BPM, so it seems like you've relaxed quite a bit.
I also had Miyu take a look and compare it to the average heart rate of women in their 20s.
Next, I had them change the position where they placed the stethoscope.
It's said that "you can't hear very well if you're far from the heart," so we had Miyu experience the difference in how well you can hear depending on where you place the device.
She also drank some water, and the moment she swallowed, her heart rate increased, indicating that her autonomic nervous system was functioning properly. Miyu, who was listening, asked, "Why does my heart rate increase when I drink?", showing her interest in the heart.
Finally, we had her take a deep breath and listen to the difference in heart rate between inhaling and exhaling. The change during inhalation was noticeably faster compared to the other models, indicating sinus arrhythmia, which is very healthy.
Miyu was apparently impressed by how her heartbeat changed when she took this deep breath during the photoshoot, and it seems to have sparked her further interest in the heart.
Next, I was asked to stand up while the doctor placed a stethoscope on my chest and listened to my heartbeat.
I could clearly feel the difference when I took a deep breath, but my heart rate didn't seem to change much when I was standing. Miyu also said, "It doesn't seem to have changed much."
If you squat down from there, your heart rate only slows down a little, but if you stand up again, it becomes quite fast for a moment, with a "thump, thump, thump" sound. The change in heart rate is more pronounced when standing up than when sitting down, which suggests that the act of standing up requires more blood to be sent to the body, resulting in a faster heart rate.
His heart rate had already increased just from standing up, but next, he was asked to do squats, which involve doing that continuously.
Less than 30 seconds after it started, my heart was already beating fast, and it felt like the rapid "thump, thump, thump" I felt when I stood up earlier was continuing the whole time.
Miyu, who regularly exercises in some form, said it wasn't too strenuous, but her heart rate definitely increased, reaching about 115 BPM right after it ended. It seems that even with regular exercise, her heart rate easily exceeds 100 BPM.
Miyu also said, "It might be the fastest!" And not only is it fast, but the sound itself is incredibly loud, so loud that it's almost annoying. But if it were to become quiet, I'm sure I would pass out immediately.
Immediately after it ended, my heart continued to beat rapidly, but I recovered relatively quickly and eventually calmed down.
Next, we had them do step-ups.
It's said that this isn't as strenuous as squats, but as mentioned in the sample video, she's exercising seriously, and listening to her heartbeat, it rises faster, reaching the same speed as when she finishes squats within seconds of starting, and the heartbeat is also louder. Thanks to Miyu's skillful use of the stethoscope, there's little background noise despite the intense exercise, and the heartbeat is easy to hear.
After it was over, I had her place her hand on her chest and feel the vibrations, and she said, "It's fast, so it might be easy to feel!" She stood there for a while listening to her heartbeat, and then I had her sit on the bed.
When he sits down, his heartbeat slows down, but after a while he yawns, and I can hear his heartbeat quicken up.
Even the slightest movement can cause a change in the heartbeat, so it's never boring to listen to.
Finally, we had him lie down on the bed, but the beat rate remained around 74 BPM, not much different from when he was sitting. He had worked so hard exercising that he might not have been completely settled down yet.
When listening to the heart sounds during chest compressions, Miyu's heart appears to be easily affected by the compression, as the rhythm is unstable, sometimes speeding up and then slowing down, then speeding up again, like "thump-thump-thump-thump, thump, thump, thump, thump, thump-thump-thump."
When the pressure was released, the heartbeat had slowed down, so it seems the unstable rhythm during the pressure was indeed due to the ****ful pressure I applied.
When I held the camera in my other hand and applied pressure again, the camera shook slightly in time with the heartbeat, and at the same time, both my hand applying pressure and Miyu's hand holding the stethoscope shook simultaneously, allowing us to visually observe the movement of Miyu's heart. At that time, the heartbeat seemed to speed up and then slow down again, with an unstable rhythm, making it easy to see the changes caused by the pressure.
Finally, we applied pressure while the patient was seated, and then released it, at which point the patient stood up.
No change in heart rate was observed when pressing while sitting, and the unstable rhythm mentioned earlier seems to be something that can only be heard under the specific condition of pressing while standing.
When I stood up after being released from the pressure, my heart rate was quite fast again, and in fact, it felt even faster than when I first stood up.
For the filming of exercise while breathing into a bag, participants were fitted with an electrocardiograph and stethoscope, then had a bag placed over their heads, sealed, and performed leg-raising exercises.
Before starting, my average heart rate was 67 BPM, but it increased as I began exercising, reaching 80 BPM after only a short time.
From there, her heart rate continued to rise, but the way it increased was similar to when her chest was compressed; her heart rate would speed up and then slow down a bit, with fluctuations in speed, and it gradually increased. It seems that not only chest compressions, but also this kind of strenuous exercise can cause an unstable rhythm. At the same time, her oxygen saturation began to decrease, indicating that oxygen was definitely being consumed in Miyu's body.
She said, "I'm tired," and put her feet down, so it seems that even Miyu, who exercises regularly, gets tired from continuous exercise in a low-oxygen environment.
I removed the bag once, and at that time the oxygen saturation level dropped to 78, which is on the low side.
After a while, I tried sealing the bag again, and to my surprise, instead of saying it couldn't do it anymore, it started exercising again. It's really putting in a lot of effort.
However, the movement is slow and somewhat unsteady, and it seems that moving a body that is deprived of oxygen is quite challenging.
She raised her hands at the end, and when the bag was removed, you could tell from Miyu's breathing that she had pushed herself to her limits.
The oxygen saturation level, which had dropped, did not immediately return to normal even after the bag was removed; it took some time to recover.
During the echocardiogram and heart sound examination, when the probe was placed on the heart, an oval-shaped image of the heart appeared on the screen, and Miyu was very interested in seeing her own heart for the first time, saying things like, "Is this it? I thought it would be bigger!" and "Is this a view from directly above?"
Miyu also mentioned that it was "only about the size of a clenched fist," so I think what's shown in the video is indeed the same size as the real thing. This thing is constantly moving without rest deep inside Miyu's chest, and we can catch a glimpse of a part of it like this, for which we should be grateful for the progress of modern science and technology.
When I asked the patient to take a deep breath, their heart rate seemed to increase, but for a moment, their pulse skipped, and the ultrasound screen showed that their heart had stopped beating for a moment. It started beating again immediately, but because they were exhaling, the movement was slower.
We were able to see even the movement of its heart at the moment of takeoff, which was an incredibly precious moment.
We have created a separate video containing the ultrasound footage, so please check there to see the heart's movement as it briefly stops.
Next, we check the heart using echocardiography immediately after exercise.
The video starts immediately after the exercise is finished. For reference, the exercise performed was step aerobics.
As Miyu lies down, you can hear her heart beating rapidly, indicating that she has just exercised. When we apply the probe, her heart is beating faster than before, and although it might be due to the way the probe is positioned, her heart also seems larger than before.
When it's shrunk, it looks about the same size as normal, but when it's inflated, it feels bigger than Miyu's fist.
After taking a deep breath, the speed had calmed down considerably, but the size still seemed large.
Please note that due to equipment limitations, the echo image is not included in this video.
Finally, we were able to hear the sound of her heartbeat while she was masturbating. First, she answered some erotic questions. Judging from the content of the questions, they were some rather daring things that you wouldn't normally ask even in a close relationship, and as she answered, her heartbeat quickened a little, and you could tell from the change in her heartbeat that she was feeling embarrassed.
From there, they remove their swimsuits and, in a fully nude state, masturbate using adult toys.
Occasionally, she would let out a breathy moan, and her heart would quicken at those times, but it didn't seem to be enough pleasure for her to reach orgasm. She changed the way I applied pressure and intensity several times, and when I hit the sweet spot, she came very quickly, in just seconds. She cried out, her body trembling, and said, "Ah, I'm coming," and her quickening heartbeat showed that she was really getting it.
Even after she had finished, I continued to stare at and photograph Miyu's beautiful naked body for a while, but she got embarrassed and angry, saying, "Don't stare at me like that! Stop it!"
When Miyu, who is usually so serious and quiet, said that to me, it felt like a reward, and it only made me want to see more. She was covering her private parts with her hands, so I asked her to move them, and finally, I took some more close-up shots of her whole body. Miyu's embarrassed expression combined with the photos made me incredibly excited.
Miyu's heartbeat had an unstable rhythm at times, and she herself showed interest in her heart, making it a video that was both engaging and fascinating to watch.
