Thank you for visiting.
This is a video of the heartbeat of Yumi, 23 years old, who is as cute as an idol.
She had a small face and white, smooth skin, and was as cute as a doll.
Although she was wearing a mask, her cuteness still oozed out.
She was also so thin that I thought her body might break, and I really thought she could be in an idol group somewhere.
He has a gentle personality and gives off an aura that is soothing to be around.
This time we are also taking photos using ultrasound.
The contents are:
・Self-introduction and heartbeat
- How do you feel when you hear your heartbeat under normal circumstances?
Heart sounds when standing and sitting
- Heart when chest is compressed
- Heart sounds during and after squats
- Heartbeat during and after stepping up and down the platform
- Heart movement and heart sounds when an echo is applied under normal circumstances
- Heart movement and heart sounds seen with an ultrasound after exercise
- Heart sounds when exercising with a bag on your head
・The sound of your heart when you're doing that
The video is 52 minutes and 19 seconds long.
First, I had a stethoscope placed on my face to listen to my heartbeat.
Her heart rate is about 70 BPM. It's relatively slow, but when I asked her if she was nervous, she said, "A little bit."
When I asked him if he had ever been told that he had a heart problem, he said that he had only been told once that he had an arrhythmia.
This time, Yumi herself listened to her heartbeat.
He was told that it might be surprisingly fast, and apparently his own heartbeat felt faster than he thought.
When we listened to his lungs, he cutely said, "I can hear you breathing."
If you hold your breath during the session, your breathing will slow down a little. When you resume breathing, your breathing will speed up a little, and you will be told, "That's fast!"
When we asked him to touch his carotid artery, he said, "I feel my heart with my hand and ear," which really appeals to those with a fetish.
Next, we ask you to compare the heart sounds while sitting and standing.
When standing up from a sitting position, the patient's heartbeat also becomes faster, and he has commented that it has become ``just a little faster.''
When we had him sit down again and attached the pulse oximeter, his heart rate was displayed as 66 BPM. When we had him stand up, his heart rate immediately rose to nearly 100.
It's amazing how much of a difference just this can make in your heart rate. Yumi couldn't hide her surprise, saying, "It goes up so much!" and "Amazing!" She also made an amusing description of the change in her heart rate, saying it was like riding a roller coaster.
When I pressed on his heart, his body was so thin that I thought it might burst if I pressed too hard, but I asked Yun-san to let me press as hard as I could.
My whole arm is shaking violently, proving that I'm pushing with all my might. This isn't due to me shaking, but to Yumi's heartbeat. I zoomed in on her chest area and you can see that it's shaking even more. It's not just my hand; Yumi's body is shaking with her own heartbeat.
As an aside, you can see faint marks on Yumi's chest from the stethoscope that was placed on her during the previous photo shoot.
The heartbeat is getting faster, and the sound is telling us that our lives are in danger.
When the pressure was released, he had a look of relief on his face.
This time we're doing squats.
This video is probably the only one where you can hear Yumi's heartbeat, which gradually gets faster as she does squats, something you would never hear in a normal day to day life.
You can clearly see that the speed increases with each squat.
Even after it was over, her heart continued to beat quickly for a while, which she cutely described as "pounding like a drum." When she placed her hand on her chest, it seemed like she could feel her heart beating.
If you take a deep breath, you will notice that your rapid heartbeat will gradually calm down.
Next, we will have him do some more strenuous step-ups.
It seems he doesn't exercise much on a regular basis, and his legs are already shaking.
This is also done with a stethoscope placed on my body, so I can feel my heartbeat gradually getting faster.
Right after it's over it's so amazing, my heart is beating so hard I feel like it's going to explode.
My heart rate was about 120 BPM, which is probably twice as high as normal.
Yumi also said, "I'm going backwards and forwards," and she was out of breath and breathing heavily.
At one point, when I focused the camera on the area around the solar plexus, I could see it twitching.
Finally, I asked him to take another deep breath and calm his heartbeat.
Next, we used an ultrasound to look at Yumi's heart.
What is going on in the heart of such a cute girl?
When the probe coated with a special gel was placed on Yumi's chest, she let out a cute "whoa" as she felt the coldness of the gel.
The screen shows the rhythmic movement of Yumi's heart, beating in time with her heartbeat. It's exciting to think that such a mysterious organ exists inside Yumi's slender body.
Yumi, seeing her own heart for the first time, couldn't help but say, "It's beating."
We have been able to observe the movement of the heart from various angles, and when they look at it from a certain angle, they say, "It looks like a heart!"
This time, we tried looking at the heart with an ultrasound while the patient was sitting.
It looks different from when you are lying down.
"It looks like a head of broccoli," she says, another cute description.
When he breathed in, part of his lungs was also visible.
Next, we use an ultrasound to check the movement of the heart immediately after the patient steps up and down the step.
The video starts just before the step-ups finish.
When we placed the probe, we could see that her heart was beating at a much faster rate than before, pumping blood throughout her body with all its might.
I was surprised at how fast it was, saying "It's so fast!"
I could also feel Yumi's heartbeat through the probe in my hand, which made me feel really excited.
From there, we were able to see the heartbeat gradually slow down, and he also commented on this.
To measure the heartbeat during exercise while wearing a bag, participants lie on a bed with the bag sealed over their head and perform intense leg-raising exercises.
About 30 seconds into the exercise, he was already struggling to breathe. He raised his hands several times during the exercise, so we loosened the bag a little, but quickly resealed it to prevent fresh air from entering the bag.
Towards the end he was gasping for breath and looked extremely distressed.
Still, all that enters Yumi's lungs is used-up air high in carbon dioxide, and as if to prove it, the oxygen concentration on her pulse oximeter has dropped to around 79. Her heart rate has skyrocketed to 120 BPM. It's beating so hard it feels like her heart might give out.
This must be extremely painful. Yumi also exclaimed, "This is so painful!"
When the bag was removed, he breathed voraciously, ventilating his lungs with fresh air.
At the end, we recorded the sound of her heart beating as she engaged in some naughty acts.
She looks embarrassed as she has the electric massager on her, and she closes her eyes and moans softly. Her body moves every time she feels it, and just this alone is already erotic.
As she continues, her moans get louder than at the beginning, and finally she reaches orgasm, saying "Ah, I'm coming." She's so sexy and cute.
My heart was beating faster at that time too.
You'll never see Yumi, who is as cute as an idol, in such an embarrassing state, and you'll definitely only be able to hear the sound of her heart beating in that state in this video.
