Thank you for viewing.
This is the second heartbeat of Mikuri, age 25.
She had a very approachable way of speaking, and was so friendly that it was hard to believe we had just met. She was also very charming, fair-skinned, and despite her slender figure, she had a nice bust, making her a photogenic model.
It also appears that Mikuri had been diagnosed with an irregular heartbeat at a hospital in the past. When we actually listened to her heart, it wasn't particularly noticeable when she was sitting, standing, or exercising, but when she was lying down and resting, her heartbeat would suddenly become extremely slow.
It's probably a bradycardia-type arrhythmia.
She had a different type of arrhythmia than Miina and Reina.
We were able to detect a slight movement that resembled a heartbeat in the second heart sound as well.
The contents are
- Heartbeat sounds when standing and when bending over
- Heartbeat when lying down
- Blood pressure and heart sounds when lying down and sitting up
- The sound of your heart when you do step-ups at full speed
- Carotid artery pulse and heart sounds
- The sound of your heart when you strike a sexy pose
• Heartbeat while smoking
Electrocardiogram and heart sounds during squats
Electrocardiogram and heart sounds during masturbation
That is the case.
The video is 41 minutes and 47 seconds long.
To hear your heart sounds while standing and while bending, we had you listen to your own heartbeat using a stethoscope while standing.
When I was sitting, it felt like around 73 BPM, but when I was standing, it seemed faster than that.
When we asked Mikuri-san about it, she said, "I'm faster when I'm standing," and it seems she understood the difference in speed.
When she did some stretching exercises, her heart rate increased, and Mikuri seemed to notice it too. The moment she realized it, she smiled and said, "It's gotten faster!" She seemed happy to notice the change in her heart rate.
For the heart sounds while lying down, we recorded the heart sounds while the patient was lying down in bed and resting.
No irregular heartbeat was observed, but the heart rate was slower than when standing.
I had them stretch again, and I listened to the changes in their heart sounds.
"Hmm? Has anything changed?" she said, stretching a few times and listening carefully. It seemed she noticed that the pace had become slightly faster.
And finally, when they stood up, the "dock, dock, dock, dock" suddenly became faster, and I listened to them saying, "Fast, fast, fast!"
Next, I took your blood pressure.
When we first measured your blood pressure while you were lying down, it seemed a little low. However, your systolic pressure is still above 100, so it's not extremely low.
When Mikuri-san also took a look, she said, "You seem to have low blood pressure."
Furthermore, the sound of her heart at that time was characteristic of Mikuri's, with sudden slowdowns, and there were also movements that seemed to stop, like "thump, thump, thump, thump, thump, thump, thump." The blood pressure monitor did not show any arrhythmia, but listening to her heart, it was clear that the rhythm was not stable.
Also, when we measured her blood pressure while she was sitting, it was higher than when she was lying down, but it wasn't high enough to be considered hypertension, so her blood pressure was perfectly healthy. Mikuri also said the same thing after seeing the results.
Also, since the heart rate is faster when sitting, the numbers show that the load on the heart and blood vessels differs depending on the posture.
To hear the heartbeat when doing step-ups at full speed, we asked Mikuri to do step-ups at full speed for about two minutes, using all the strength she had.
They would say things like, "This is tough!" and then look at the timer midway through and say, "Just a little more!" and push themselves to the end. At first, it was difficult to hear their heart sounds due to the rubbing noise of the stethoscope, but as they continued exercising, their heartbeats gradually became faster and more powerful, and they were able to hear the sounds even with the rubbing noise.
The fact that it's not just fast but also loud means that the heart valves are opening and closing very vigorously. I can imagine Mikuri's heart beating intensely inside her body while she's exercising.
Towards the very end, it was like "thump-thump-thump-thump-thump," so fast that anyone who heard it would think, "Wow!" I think my heart rate was probably around 130 BPM.
Immediately after it's over, they sigh "Ahhh" and collapse onto the bed, looking utterly exhausted.
When I placed my hand on Mikuri's chest at that moment, I could feel the tremendous pounding of her heart, so much so that it felt like it was going to burst through my chest.
Even a woman like Mikuri's heart starts pounding when she does such strenuous exercise.
I also gave Mikuri-san some earphones, and after she listened to them, she said, "It's so fast, it's amazing!"
From there, we had him lie down until his heart rate calmed down.
Her heart, which had been beating so frantically, gradually began to calm down, and Mikuri said, "I'm feeling a bit calmer now!"
However, each heartbeat is very strong, so it seems he hasn't fully recovered yet.
Finally, I also measured my blood pressure, and even though I was lying down, the reading wasn't much different from when I was sitting. It seems that my blood pressure was definitely affected.
In the carotid artery pulsation and heart sounds, Mikuri's carotid arteries were clearly visible, especially on the right side, where the blood vessels seemed to bulge out as they pulsed. We focused our filming efforts on that side.
The pulse rises on the "thump" part of the heartbeat, and conversely, recedes on the "thump" part, moving in sync with the heartbeat. When you place your finger on it, you can feel it twitching, and even in the video, the carotid artery pulsation disappears when you place your finger on it. If you press too hard at this point, the person will surely lose consciousness.
Even when photographed from a distance, it was clear that it was moving.
We can also see a pulsation on the left side, but it appears to be moving in a way that the base of the neck is bobbing up and down, so the appearance is different on the left and right sides.
When she struck sexy poses, her heartbeat was audible. She took on various poses on her own without us having to ask her to, and she even smiled when we zoomed in, so she seemed very comfortable with it.
We asked her to strike poses that boldly show her armpits and poses that emphasize her chest, and finally, she even struck a daring pose with her legs spread in an M shape.
Because Mikuri has such a great figure, this photoshoot looks fantastic on her.
Also, when she changes poses, her heartbeat quickens slightly, and the sound of her heartbeat that you hear is definitely Mikuri's.
The photoshoot involved her wearing a swimsuit, but I can't help but imagine what she would look like without it.
In "Heartbeat 1," there are parts where she is fully nude, so if you want to see Mikuri naked without a swimsuit, please check that out.
For the recording of heart sounds while smoking, we asked Mikuri, who smokes, to smoke during her break, and we filmed it at that time.
I'm worried about whether it's okay to inhale something when I've been diagnosed with an arrhythmia.
Mikuri, who normally doesn't listen to the sound of my heart while I'm smoking, chuckled midway through and asked, "How is it? Is there any change?"
When I actually listened to it, it seemed a little faster.
For the electrocardiogram and heart sounds during squats, participants performed squats while wearing an electrocardiogram monitor.
Due to equipment limitations, we only took an electrocardiogram and did not measure oxygen saturation.
Please note that the electrocardiogram readings may be slightly difficult to read.
Of course, we can hear the electronic sounds from the electrocardiograph and your heartbeat, so please don't worry about that.
When she started squats, her heart rate was around 84 BPM, but it gradually increased, reaching 100 BPM after about a minute, and Mikuri exclaimed, "Wow, it's over 100!"
After that, my heart rate continued to rise steadily, exceeding 110 BPM right after I finished. I was surprised that it rose so much after only about two minutes of squats, and it was also easy to see how my heart rate was increasing while I was taking an electrocardiogram.
They say, "Wow!" and tell you how much your heart rate has increased before and after the session.
When I also touched her carotid artery, she exclaimed, "Oh wait, I can feel it pulsating even without you touching it!" It seems she could feel the vigorous movement of her carotid artery even without strong pressure.
It must have been moving very strongly.
Finally, I was asked to take a deep breath to calm my heartbeat, and as a result, the heart rate on the electrocardiograph returned to about the same level as before the procedure began.
Finally, we had the subject masturbate while wearing an electrocardiogram, and observed the changes in the waveform and heart rate. We also listened to the heart sounds with a stethoscope, so not only the heart rate but also the strength of the heartbeat was conveyed through the sounds heard through the stethoscope.
It's embarrassing enough to be seen doing something like this, but to have your heart rate monitored at the same time... I think that's quite a **** experience.
Before we started, I asked her some slightly naughty questions about masturbation, and she already seemed embarrassed when she answered them. Just asking these kinds of questions is already a form of **** play.
Then, they used an electric massager and performed the act.
Occasionally, he would change the intensity of the electric massager and put his hand inside her swimsuit again, and she would let out soft moans.
I wonder if she does this at home on a regular basis. Just looking at her like this is incredibly erotic.
Her heart rate, which was around 60 BPM, continued to rise steadily throughout the act, occasionally dropping slightly, until it exceeded 83 BPM. The beats of her heart, as heard through the stethoscope, became stronger with each beat, and she said, "I'm about to come," giving the impression that she was close to climaxing. A few seconds later, she came, moving her hips and shouting, "Ah, I'm coming, I'm coming!"
What's interesting is that immediately after reaching the peak, the heart rate starts to decrease rapidly.
It had been rising for a while, but then it started to drop the moment it reached its peak, so by looking at the heart rate, you can pretty much predict where it reached its peak.
Immediately after reaching her climax, she had a slightly embarrassed expression on her face.
The format is "MP4".
