Thank you for viewing.
This is the first heartbeat of Rena, age 23.
She's slender, has fair skin, and is genuinely only 23 years old, born in 2003. I'm really happy that recently I've been able to photograph mostly relatively young people.
Rena, who has a straightforward and mature personality, has an average heart rate at rest, and at first there were no abnormalities, making her seem healthy at first glance. However, perhaps because she had been doing strenuous exercise multiple times, in the latter half there were instances where premature contractions occurred repeatedly to a worrying degree.
The sound of a young woman's heart at the moment she experiences multiple premature contractions due to strenuous exercise is something you don't hear very often, so I'm glad they put in that much effort to film it.
The content is,
Self-introduction and heartbeat
• Reactions to hearing heart sounds and heart sounds
- Heartbeat sounds when standing and when squatting
- Heart sounds when chest is compressed
- Heartbeat during squats
- Heartbeat sounds when stepping up and down
• Electrocardiograph and heart sounds
- Electrocardiogram and heart sounds (with premature contractions) during exercise while breathing into a bag.
Echocardiography and heart sounds
• Post-exercise echocardiogram and heart sounds (premature contractions observed)
- Heartbeat sounds during masturbation
That is the case.
The video is 55 minutes and 50 seconds long.
We started with an introduction and a heartbeat. I listened to my heart with a stethoscope and found that my heart rate was around 78 BPM, which is an average speed, and the rhythm was normal. I could hear the heart valves opening and closing properly, making a "thump, thump, thump" sound.
She said she wasn't nervous, so I guess Rena's heart rate is probably around the same as usual.
I'm really looking forward to seeing how that will change after I start exercising and masturbating.
During filming, she also answered questions such as, "What did you think when you first heard that we would be filming your heartbeat?" and "Are you embarrassed to have your heartbeat heard?"
During the photo shoot where she listened to her own heartbeat, she commented, "It's slower than I thought," upon hearing it for the first time. It seems Rena had expected it to be a bit faster.
During the examination, the patient was asked to change the position of the stethoscope to find the best location for hearing. Because her chest wasn't particularly large, the sound was clear wherever the stethoscope was placed, but she said the initial position provided the best sound.
After she drank some water, she seemed to get a little faster, and Rena noticed the difference.
When I asked him to take a deep breath at the end, his heart rate remained the same as before when he exhaled, but when he inhaled, his heart rate increased as if he was happy to receive the air, and he exhibited sinus arrhythmia.
Regarding the heart sounds when standing and squatting, we first had you listen to your own heartbeat while standing. Counting your heart rate, it was around 85 BPM, which is slightly faster than when sitting. Rena also said that her heartbeat is faster when standing.
When I asked him to squat down with the stethoscope still on, his heartbeat changed almost immediately, and he stood up again. So I asked him to squat down again and wait, and his heartbeat slowed down. When he stood up again, his heartbeat sped up immediately, and then gradually slowed down again after a while. I guess his body reacts so quickly because he's young.
When chest compressions were performed, the patient did not appear to be in much distress during the compression. However, as the heartbeat was listened to during the compression, it gradually increased in speed, and then slowed down again when the compression was released.
She didn't seem to be in much pain during the compression, but when I asked her after the shoot, she said it was quite painful, so it seems she was enduring it.
The second time, when I applied pressure while holding the camera, the vibrations of Rena's heartbeat were fully transmitted to the camera, causing it to shake and the screen to shake as well. As her heartbeat quickened due to the pressure, the camera's shaking also quickened accordingly. It seems that her heartbeat was very strong and she felt her life was in danger from the external ****.
Finally, when I zoomed in on her chest and applied pressure, I could see my hand moving in time with her heartbeat. Seeing it visualized like this, I could see that the heart, which I had only heard as sound, was actually inside Rena's body and beating.
Despite having a good physique, this person says they don't exercise regularly, and their heartbeat seems to become faster and stronger as they bend their legs and lower their hips during the squats.
After the squats were finished, Rena listened to her heartbeat and said, "I feel like it's gotten faster." She also said that she could feel her heartbeat when she placed her hand on her chest, and although each beat seemed strong, her heartbeat had indeed become slightly faster in response to the strenuous exercise.
Judging from her fast heart rate, perhaps because she's young and has good stamina, squats might not be such a strenuous exercise for Rena. Finally, we had her take some deep breaths and asked if she noticed any changes.
Next, we had Rena try step-ups, which are even harder than squats.
This one drains a lot of energy, so I think it's much harder. Rena also said this one was tougher, and more importantly, her heart rate gradually increased while she was doing the step-ups, and right after she finished it was over 120 BPM, which is clearly faster than squats.
"It's beating really fast!" she said, placing her hand on her chest, and it seems the intensity of each beat is different compared to when she's doing squats.
Taking a few deep breaths will slow things down, but it's still much faster than before you started. Your heart is working hard to replenish the oxygen that was consumed during the exercise.
When she sits on the bed, her heart rate has calmed down considerably compared to immediately after the exercise, and when she lies down, it's hard to believe that her heart was beating so fast just moments before; it's so slow that it almost seems like it might stop. Or rather, this is probably Rena's normal heart rate, and the time immediately after the exercise was too fast for her.
With the electrocardiogram and heart sounds, the process begins with attaching the electrodes, and once that's done, the monitor displays the waveform of the electrical signals from Rena's heart and her heart rate in real time.
The sounds of Rena's heartbeat heard through the stethoscope and the electronic beeps from the electrocardiograph were synchronized, and when I asked Rena what her current heart rate was, she replied, "It's 70!" It seems she knows which is her own heart rate. Her heart rate is also average.
Next, we had them take a deep breath and check if there was a difference in their heart rate when they inhaled and exhaled. Here, the heart rate drops sharply when they exhale and rises sharply again when they inhale, and the difference is clearly visible because the heart rate is visualized.
I also asked them to hold their breath for one minute.
At the beginning of holding her breath, her heart rate dropped slightly and then gradually increased. Her stomach was moving and it looked like she was breathing, but her oxygen saturation was slowly decreasing, so it seems she was indeed holding her breath. When I asked Rena about it later, she said her oxygen saturation had dropped significantly.
When the timer went off and the patient resumed breathing, their heart rate increased rapidly, and at around 37 minutes and 2 seconds, although not visible on the electrocardiograph, a careful listening to the heart revealed what appeared to be a premature contraction.
Next, regarding the electrocardiogram and heart sounds while the patient was exercising while breathing into a bag, there were a lot of premature contractions.
This is one of Rena's heartbeat videos that I especially want you to see.
At the beginning of the exercise, there wasn't much change, and I just felt my heart rate gradually increasing, but around 37 minutes and 54 seconds, I felt my pulse was slightly off.
After that, there was another sound that sounded like a premature contraction, and as the heart rate increased further, it started happening repeatedly, and when I listened to the heart, I heard a stumbling rhythm like "thump, thump, thump-thump, thump, thump."
On the electrocardiogram, we observed that in areas where premature contractions were occurring, there were instances where the waveform appeared twice in a row.
As she continued exercising, she started experiencing premature contractions at a rate of once every four to five beats, which was quite a mess. Moreover, the sounds of her heart heard through the stethoscope and the electronic sounds from the electrocardiograph were out of sync, which was also a mess. They had been properly linked up until then, so it made me wonder if there was something seriously wrong with her heart. I loosened the bag once and then resealed it, but the premature contractions continued to occur frequently. It seems that even Rena's heart, which was healthy under normal circumstances, can become this disrupted when she exercises in a low-oxygen environment.
Finally, the bag was removed and the patient was allowed to rest, but the premature contractions continued to occur repeatedly, and the patient was completely out of control. The oxygen saturation level dropped to a low of 85, and the heart rate exceeded 100 BPM at times, so judging from the numbers, I think the patient was well beyond their limits.
I was relieved when the heartbeat finally returned to normal towards the end.
When I asked how it went, she replied, "It was painful," which is understandable considering the number of premature contractions she experienced. Despite that, she persevered until the end, and we were able to capture some excellent video and audio.
With echocardiography and listening to heart sounds, when we place the probe to locate the heart, we can see a black mass that is moving around.
Because you're lying down, your heartbeat is slow and your heart is moving slowly.
When you held your breath, your heart appeared smaller and its movement was slightly faster.
Next, we performed an echocardiogram after she did some step-ups, and once again, premature contractions occurred. It was so frequent that we were actually worried if it was okay, but we really wanted you to see this as well. As soon as she lay down on the bed immediately after the exercise, she started having repeated premature contractions, like "thump, thump, thump, thump" and "thump, thump, thump, thump, thump," so much so that we thought it might have gotten worse than before, and her heart's pumping function was completely disrupted. When we applied the probe, we could see that her heart twitched and convulsed for a moment at the time of the premature contractions, and although Rena didn't notice, it was very clear from the video that she was having premature contractions. It's cute to see her brave heart trying its best to pump blood despite its malfunctions.
The premature contractions had subsided, so I asked you to take a deep breath as a final step. However, when you inhaled, another premature contraction occurred. It seems that even deep breathing is now causing premature contractions and negatively impacting your heart.
After the scan, we informed Rena that she had experienced premature ventricular contractions, but she said she didn't feel anything in particular. The fact that she was experiencing so many premature contractions without even realizing it, and that we were able to see them through the ultrasound, makes this a truly excellent scan.
All of these ultrasound images are from separate videos, so I especially want you to see the heart during exercise and observe the spasmodic movements of the heart.
For the segment about the sound of her heartbeat during masturbation, we had Rena take off all her swimsuits and use adult toys while she was naked.
Rena's body, with her translucent, beautiful skin, perfectly sized breasts, and her figure without a swimsuit, is absolutely gorgeous.
I'm sure my videos are the only ones where a young woman of 23 years old shows her face and masturbates, and you can even hear her heartbeat. Her facial expressions and the changing sounds of her heart as she feels pleasure are incredibly erotic.
When we inserted the adult toy, she let out a soft "Ahhh" that clearly showed how much she was feeling it. Even a mature woman like Rena can make such sweet sounds when her sensitive parts are stimulated.
After that, she repeatedly let out sounds of pleasure like "Ahhh" and "Mmm," and her heartbeat, which had been slow before we started, gradually quickened. Finally, she said "Ahhh, I'm coming," and climaxed, her breasts shaking.
After it was over, she moved her hands away, leaving her private parts completely exposed, and she looked embarrassed. I also noticed her heartbeat seemed to have quickened slightly.
