Thank you for viewing.
This is Myu, a 27-year-old model who is 170cm tall.
Not only was she tall, but she also had a slim figure with long, slender limbs, and a beautiful, small face. She was the kind of model who wouldn't look out of place in a fashion magazine.
We've had a model like that before, haven't we?
Furthermore, she has a laid-back personality and is a gentle, calm, and beautiful woman.
Myu's heartbeat was relatively slow, and despite her tall stature, I was sometimes worried about whether her heart was beating slowly enough to circulate blood throughout her body.

The video is 52 minutes and 56 seconds long.
After introducing myself, I was given a stethoscope to listen to my heart.
Her heart rate is about 78 BPM, which is about average for a woman in her 20s, but she seems a little nervous about this being her first time being photographed like this. She appears calm on the surface, but it seems she's a bit nervous inside. I wonder if her heart rate is usually slower.
Apparently, having her heartbeat heard is even more embarrassing for her than being seen naked, so I'm grateful that I'm given the opportunity to listen carefully to those embarrassing sounds with a stethoscope.
The rhythm was consistent, but when I asked a question and he answered it, his heartbeat quickened at times, and I could sense from the sound that he was feeling more nervous.
Next, I had Myu put on earphones so she could listen to the sound of her own heartbeat.
When asked if the sound of her own heartbeat, which she was hearing for the first time, was fast or slow, she said, "I think it's fast," and she also placed her hand on her chest to see if she could feel her own heartbeat.
After that, I changed the position of the stethoscope and asked the patient to listen to different parts of their body, and also asked them to tell me where they could hear best.
When you drank the water, we could hear the gulping sound as it went down your throat, and immediately afterward, your heart rate suddenly increased. The increased heart rate suggests that drinking the water stimulated your sympathetic nervous system.
Finally, we did some deep breathing exercises. The exercise involved taking a deep breath, holding it briefly, and then slowly exhaling. When inhaling, the breathing was rapid, like "thump, thump, thump," and when holding it, it was slower, like "thump, thump, thump." Usually, the exhalation is also slow, but in Myu's case, there were moments when it was almost as fast as the inhalation, like "thump, thump, thump." It's amazing how much difference there is between people, even with something as simple as deep breathing, so I'd love to hear how many more people do it.
Next, I listened to his heart sounds with a stethoscope while he was doing squats.
Since it was a squat exercise, she naturally stood up to do it, but I was once again surprised by how tall she is. Also, perhaps because she was wearing a swimsuit, she looked even slimmer.
Despite having such a great physique, she apparently doesn't exercise at all on a daily basis, and even her squats are done very slowly, but that's still enough to get her heart rate up, reaching about 96 BPM immediately after she finishes.
She said that if she placed her hand on her chest, she felt like she could feel the movement of her heart.
Finally, I asked them to take a deep breath to calm their heart rate.
Next, we had them do step-ups.
It may look like we're taking things at a slow pace, but of course we're not cutting corners.
It's said that this is even tougher than squats, and Myu is doing it with all her might.
During the step-up exercise, the heart rate gradually increased, reaching around 110 BPM immediately after finishing. We asked the person to stand there and listen to the changes in their heart rate, and it remained fast, staying at around 110 BPM without settling down. I think it was that tough for them.
If you take a deep breath, your heartbeat will gradually calm down, and if you sit up on the bed, your heartbeat will slow down even further.
When we finally had her lie down, her heart rate slowed down again, and just hearing the "thump, thump, thump," it sounded like it might stop completely. It was considerably slower than after her exercise. If this is Myu's normal heart rate, then it was definitely faster after her exercise. From this whole process, we can see that even a laid-back, easygoing Myu's heart rate does increase after exercise.
When we compressed her chest, we could hear differences in the speed and strength of her heartbeats before and after the compression. Also, because Myu is as slender as a model, the movement of her heart was very clear when we compressed it; it was so clear that it felt like it was right there, separated only by a thin layer of skin. Her slenderness certainly contributed to this, but it was also proof that we were able to compress her chest very strongly.
Before compression begins, a healthy heartbeat is heard, but once compression starts, the heartbeat slows down, and the heart sounds become quieter, possibly due to the compression.
Judging from Myu's expression, it seemed she was enduring it with her eyes closed, and at one point she even shook her head.
When the pressure is released, the **** looks relieved, and its heartbeat returns to its pre-pressure level. However, after a short while, its heart rate quickens, indicating that it was severely affected by the pressure.
When I applied pressure again, her heartbeat slowed down once more, and I even worried that it might stop if I continued like that. At one point, she seemed to lose strength in her body and nearly collapsed. When I released the pressure, her heart started beating faster as if it had remembered how to beat, and Myu seemed to regain consciousness and opened her eyes. Her heartbeat was also faster at that time.
Once again, when I brought the camera closer to her chest and applied pressure, I could see my hand moving in time with her heartbeat, but more than that, Myu's body became wobbly and she looked like she was about to collapse several times. I guess my pressure was too strong. When I released it, she returned to normal, but I hadn't expected her to become so wobbly, and it was also easy to see the change in her heartbeat.
You can see that the carotid artery pulsates in sync with the heartbeat, which beats at approximately 62 BPM, with a rising and falling motion. When you place your finger on the pulsating area, you can feel the pulse beating, tap, tap, tap. This gives you a glimpse into a part of the cycle in which blood flows through the large blood vessels in the neck to every corner of the head and then returns to the heart.
Furthermore, considering that blood needs to reach not only the head but also the capillaries at the ends of long limbs, the heart beats at a rate of about once per second. It makes me worry again about whether such a slow pace is really okay.
Next, we had the subject wear a bag over their head and seal it, then asked them to perform leg-raising exercises while we recorded their heartbeat.
We also attached an electrocardiogram (ECG) so that we can constantly monitor the heart rate and ECG waveform. The electronic sound from the ECG and the sound of the heart are closely linked, and although the heart rate was a relatively slow 65 BPM before the exercise began, it gradually increased as the exercise progressed. The exercise seemed to be difficult, as the subject put its feet down to rest midway through, but because it was breathing in a sealed bag, the oxygen level was decreasing, and it seemed that the discomfort was still continuing.
We asked her to continue exercising, but she let out a pained groan as she struggled, and when we removed the bag she let out a sigh of relief. However, her heart rate exceeded 90 BPM at that point, which must have been quite intense for Myu. Her oxygen saturation had also dropped to 88, and normally, if she exercised without the bag, her oxygen saturation wouldn't drop this low. This indicates that the bag was tightly sealed, and her body was consuming its limited oxygen.
Although her oxygen saturation and heart rate had not yet returned to normal, we sealed the bag and had her exercise again. However, she quickly reached her limit, groaning and looking distressed, and tried to remove the bag with her fingers, so we removed it again. We wanted Myu to push through a little longer, so we sealed the bag again and had her exercise, but towards the end she could no longer exercise and was coughing, so we removed the bag. She looked a bit exhausted, but she was able to breathe some fresh air for the first time in a while. She did such a tough job three times, so she really did her best.
After the bag was removed, her heart rate, which hadn't dropped before, fell below 80 BPM, and her oxygen saturation recovered to 99. It's clear that, like any other human being, oxygen is an essential energy source for survival, and that's true for Myu.
With the echocardiogram and heart sounds, we were able to see Myu's heart beating in real time.
When we apply the probe, we can see a small, round, black mass moving vigorously in time with the heartbeat. Through the ultrasound, we can see a glimpse of this life-sustaining mechanism that pumps blood throughout the body with each beat every day. If we could directly grasp this beating heart, it would stop working almost instantly, and the blood supply to the rest of the body would cease.
When asked what shape their own heart was, as they were seeing it for the first time, they seemed a little bewildered by the sight of their own heart and gave a genuine reaction.
When I asked them to hold their breath, their heartbeat slowed down slightly the moment they stopped, which gave me the impression that they were trying to conserve oxygen.
Next up is an echocardiogram and heart sounds after exercise.
Just like before, we had the patient do some step-ups before applying the probe.
Since filming equipment and other items were visible in the video, we have blurred them out.
As the exercise continued, the heart rate increased, and immediately after finishing, we had the patient move to the bed and applied the probe, but the heart rate had calmed down considerably, and was only slightly faster than normal.
However, the heart initially appeared heart-shaped, but as we changed the angle at which we applied the probe, its appearance also changed accordingly, and at one point it even appeared to be split in two.
The ultrasound images are in separate videos, so please check those out as well.
During the recording of her heartbeat while masturbating, she was completely nude. She wasn't wearing a swimsuit or anything, so her breasts and lower body were fully exposed, and her private parts were visible. I was once again captivated by her incredibly slim body.
This alone is exciting, but we also get to hear how her heart rate changes as she inserts an adult toy and pleasures herself. Her heart rate quickens slightly the moment of insertion, and she moans "Aaah" throughout the insertion, her voice is incredibly erotic. It seems that she is feeling pleasure when she moans, and her heart rate quickens at various points, so I think she must be feeling it when it speeds up.
The intervals between her moans gradually shortened, and her voice grew louder until finally she climaxed, gripping the bedsheets tightly with her hands and saying, "Ah, I'm coming, I'm coming!" Her heartbeat quickened at the moment of climax, and then she seemed to calm down afterward.
It was incredibly erotic from beginning to end, so I watched it many times, which made editing very difficult. That just goes to show how attractive Myu is.
