Rua's heartbeat

* This work is fictional, and all persons appearing in it were 18 years of age or older and were filmed with their consent.

Thank you for visiting.
This is the heartbeat of Rua, 25 years old.
I had a good idea of the atmosphere from the photos before the shoot, but when I actually met her, I was surprised to see that she was even more beautiful than I had imagined.
With a small face, a height of 168cm, slender limbs, a beautiful face and a perfect figure, she was just like a model. It wouldn't be surprising if she was approached by a talent agency.
This time, we finally managed to get Rua to allow us to take photos after we asked her for permission.
I am so happy to have had the opportunity to photograph such a beautiful person.

It is as follows.
The video is 50 minutes and 30 seconds long.

First, he introduced himself, then placed a stethoscope on my chest and listened to my heartbeat.
"I'm nervous," Rua replied, her heart beating as fast as it had just been after exercise, at about 110 BPM.
You can tell from his heartbeat that he is so tense that his heart feels like it's going to jump out of his chest.
Although he appeared calm on the outside, I could sense his heart beating with tension inside, and I was drawn in by this contrast.
We also asked questions about the heart, such as, "What did you think when you heard that you would be filming the sound of the heart?"

Next, we asked them to listen to their own heartbeat through earphones.
He still seemed nervous, and when he heard his own heartbeat for the first time, he said, "It's really fast."
Once, she put a stethoscope to me and compared the sound of her heart with mine, and she laughed, saying, "About the same?" I was nervous in front of this cute girl, and Rua could tell. (Note: My heartbeat was not recorded in this scene.)
This time, when I asked her to hold her breath, her fast heartbeat slowed down for a moment, and Rua said, "It's slowed down." However, it quickly returned to its original speed, so next I asked her to take a slow, deep breath, and her heartbeat slowed down a little, perhaps because her tension had been relieved.
However, it's still a little fast, so Rua's heart rate may already be high to begin with.
Finally, when he drank some water, his heartbeat became even faster, and he laughed, saying, "What? That's so fast!"

For the heart sound during squats, we asked participants to listen to their own heart sounds with a stethoscope and then squat in that position.
He doesn't usually exercise, so as soon as he started, his heartbeat changed, and his already fast heartbeat accelerated and became even faster.
Torua also said, "It's getting faster."
Immediately after finishing, my heart rate was at an extremely high 130 BPM and I was a little out of breath, which shows how difficult squats are.
He said, "It's so much faster than before," and had me place my hand on his chest to feel his heartbeat and touch his carotid artery to experience the change.
Finally, we asked them to take a deep breath. When they inhaled slowly, their heartbeat slowed down, but when they exhaled, it sped up, showing a change in rhythm linked to their breathing, a phenomenon similar to respiratory sinus arrhythmia.

Just like with squats, the stethoscope was placed over the patient's heartbeat during and after stepping up and down the step.
There is some noise when stepping up and down the step, but you can also hear your heartbeat, and I think it's easier to hear the changes in your heartbeat than when squatting.
Immediately after finishing, his heart was beating at 145 BPM, faster than when he was doing squats. When we asked him to wear earphones to listen to his own heartbeat, he said, out of breath, "It's so fast, ha ha." This must mean that step-ups are that tough.
Here too, if you take a deep breath at the end, the rhythm of inhaling slowly and exhaling quickly is clearly recorded.

When I compressed her chest, I could hear her heartbeat and I was able to press down on her chest quite hard with my hands.
You can feel my hands shaking in time with Rua's heartbeat. Her heart rate was gradually increasing due to the strain of the pressure, and she began to feel dizzy and pale, looking like she was about to collapse, so we stopped midway and had her lie down on the bed. This entire session is also recorded uncut. There are some parts where my voice is heard, so the audio has been cut out for those parts.
When I put the stethoscope on him again after he lay down on the bed, I noticed that his heartbeat had suddenly slowed down, which may have been because he was lying down. He also seemed to be stumbling several times, and if I were to describe it in sound, it would sound like "thump, thump, thump, thump, thump, thump," to the point where I thought he might stop.
When I asked Rua, she said it was "extremely slow."
After a while, his heart rate gradually improved, and when he sat down and I checked his heartbeat again with a stethoscope, it had returned to its normal rate.

When taking an echocardiogram and heart sounds, we usually use the echocardiogram once before taking the picture to check the position of the heart, but since Rua has large breasts, it was difficult to determine, but we were able to see her heart moving by adjusting the way we placed the echocardiogram.
In the video, you can see the heart shrink at the "thud" of the heartbeat and get bigger at the "kun" of the heartbeat, so the sound and movement are properly linked.
It's quite mysterious that such a small body can house a heart that beats without rest.
Rua also said it was amazing when she saw her own heart for the first time.
When we asked them to hold their breath, no change was observed while they were holding their breath, but when they resumed breathing and exhaled, we could see that their heart rate increased accordingly.
We have also recorded footage of this ultrasound, so please check that out as well.

For the post-exercise echocardiogram and heart sounds, we performed an echocardiogram immediately after the patient had stepped up and down a step.
The video starts just before the step-ups finish.
Since she had just exercised, her heart rate was not only fast, but I could also feel her heart beating powerfully. I could also feel Rua's fast heartbeat through the probe, which got me excited. Rua was also surprised at the difference in speed, saying, "It's so fast!"
Unlike normal times, Rua's heart is working hard to circulate more oxygen throughout her body. I think this is the only video where you can see Rua's heart beating so hard, so it's extremely valuable.
During the procedure, I asked the patient to take a deep breath. When I took a deep breath, my heart rate suddenly slowed down, and the movement of my heart was clearly visible on the ultrasound.
This ultrasound image was recorded in the same way as normal images.

The blood pressure and heart rate measurements when lying down were originally planned to be taken while sitting and standing, but due to an equipment error, results were only obtained when lying down.
Rua said that she found it hard to get up in the morning, and when her blood pressure was actually measured, it was found to be quite low, with a systolic blood pressure of less than 100.
"It's so low," Torua said, laughing but also surprised.

To measure the heart rate while exercising with bag breathing, participants lay down on a bed and performed leg-raising exercises while the bag was placed over their heads to seal the air.
The bag expands and contracts in time with Rua's breathing, and it is clear that she is only breathing the air inside the bag.
At first, he is breathing normally, but as the oxygen becomes thinner, he starts to breathe deeply in an attempt to take in as much oxygen as possible.
Even so, the air that comes in is worn out and low in oxygen, so it seems like it would be quite painful.
Rua is in so much pain just from having her head wrapped in a bag, and just like us, she can only take in enough oxygen through her mouth and nose.
We have loosened the bag several times, but it has been quickly resealed, so the ****s are working hard in extremely low oxygen conditions.
His breathing seems to be hyperventilating and he seems to be at his limit.
Not only is the heart beating fast, but each beat is powerful.
The sound of the heartbeat tells us that the body is working desperately to get as much oxygen as possible into its body.
When the bag was removed, he was still drowsy, but his chest was rising and falling repeatedly to take in fresh air, and his heartbeat was gradually calming down.

At the end, we had the chance to hear Rua's heartbeat while she was doing something naughty.
Not only did she appear on the show, but she also showed us embarrassing parts of herself that she would never show to anyone, and even let us hear her heartbeat at the time. I can't thank Rua enough for that.
I asked her some naughty questions and had her use adult toys.
She seems to be very sensitive, and when I use it she lets out a sigh and looks very pleased.
Halfway through, I started making noises because it felt so good, and my heart was beating faster.
As she cries out "I'm coming, I'm coming," her body trembles and climaxes, and at that moment her heart beats at its fastest, showing that she's really climaxing.

We asked Rua to do a lot of difficult things throughout the shoot, but she responded sincerely to all of our requests, which made for a really great shoot.
