Thank you for viewing.
This is the first heartbeat of Rika, age 25.
She was a slender, blonde beauty with a toned, slim body, well-shaped breasts, a perfect figure, bright hair, and a refined face. Rika had an active and cheerful personality, and had previously studied in the medical field, so she seemed interested in medical procedures and contacted me when she learned about my photoshoot.
The filming was very enjoyable, and we were able to shoot for quite a long time, which is why this video is over an hour long.
In stark contrast to Rika's bright and energetic appearance, her heartbeat was slow and calm, and at times her heart rate even dropped below 60 BPM, indicating bradycardia. This contrast with her active image was very appealing.

The video is 1 hour, 6 minutes, and 57 seconds long.
During the initial self-introduction and heartbeat check, when you placed the stethoscope on me, you could hear a calm "thump, thump, thump" and my heart rate was about 74 BPM.
During the procedure, the doctor moved the stethoscope several times, mainly around the apex of the lower breast, and the sound varied depending on where it was placed.
When I asked if she could feel her own heartbeat through the hand holding the stethoscope, she pressed the stethoscope against her chest, closed her eyes, and tried to feel her heartbeat, saying that the area around the apex of her heart was the easiest place to feel it.
I asked her various other questions, and one of them was whether she would let her boyfriend listen to her heartbeat if he had a heart fetish. She said of course she would, and even that she would want him to listen every day, which made me, a listener, incredibly happy.
I would love to hear the heartbeat of someone as beautiful as her every day.
Also, perhaps because I was embarrassed, my heart started beating a little faster at that time.
Next, she listened to the sound of her own heartbeat. Rika, who is interested in medical procedures, seemed very excited about this, saying she wanted to hear it as soon as possible even before the filming started.
He said that his own heartbeat sounded "typical." He mentioned that it sounded like what you hear on TV, but slower than he expected.
Indeed, given Rika's high energy level, I feel like her heart rate could be a little faster.
When the doctor changed the position of the stethoscope, the patient said that in some places it sounded like being in a cave, but when the doctor placed it near the apex of the heart, it was easier to hear, and that it felt more like the heart! The doctor continued to move the stethoscope around and carefully listen to the heart sounds. It seems the doctor really enjoys performing medical procedures.
We also listened to the patient's heartbeat as they drank water. Their heart rate increased the moment they took their first sip, and they commented that it had become slightly faster. They continued to drink water several more times and asked about the difference.
Finally, I had her take a deep breath, and her heart rate increased slightly as she inhaled, but it was still relatively slow, and Rika said she couldn't really tell the difference.
I wonder if Rika is less prone to respiratory arrhythmias.
Even so, she kept trying her best to take deep breaths and listened intently to see if there was any difference in the speed of her heartbeat.
Up until this point, Rika's heartbeat has been on the slower side, but from here we moved on to filming exercise-related activities. We had her do squats to speed up her heart rate. She did each squat slowly, but that seemed to put extra strain on her, and we could see her slow heart rate gradually increasing. It just goes to show that even the most beautiful person or someone with a slow heart rate will have their heart rate increase with exercise.
Rika also said, "It's getting stronger!" and "My heart's beating really fast!", and it seems she could feel her own heart beating faster even while doing squats.
Immediately after it was over, Rika's heart rate was 95 BPM, the first time it had been in the 90s during the shoot, and she said, "It's so fast, it's almost too fast!" It seemed to her to be quite fast. Finally, we had her take a deep breath. When she slowly inhaled, her heartbeat calmed down for a moment, but when she exhaled, her heartbeat quickened again, and it seemed like a respiratory arrhythmia, with a slight disruption in her rhythm.
Next, when we had him do step-ups, he didn't seem to be struggling that much at first, and even said that the squats were harder. However, as the session progressed, his expression became more strained. His heartbeat, which was initially slow and difficult to hear, became faster and louder, and was clearly faster than when he was doing squats.
For the last 30 seconds, they were running at full speed, and during that time they were shouting, "It's tough! It's too tough!" It seems that this is definitely tougher than squats, as their heart rate immediately after finishing exceeded 140 BPM, which is much faster than with squats. Since their initial heart rate isn't that high, I think the strain on their body must be considerable when it rises this much.
I had Rika put on earphones so she could hear her own heartbeat, and while she was putting them on, I placed my stethoscope over her chest. Even though I wasn't touching her chest, I could hear a very fast beating through the stethoscope. I could clearly hear her heart literally beating furiously inside her slender body. As Rika listened to her own heartbeat, she exclaimed, "It's so fast! Ha, ha, it's so fast!" out of breath.
If you place your hand on your chest, you should be able to feel your heartbeat much more strongly than usual.
That probably means the heart's movements are becoming more vigorous.
Just like when doing squats, if you take a deep breath, your heart rate will slow down when you inhale, and then speed up again when you inhale slowly once more.
It was difficult to notice during normal times, but respiratory arrhythmias become much more pronounced and easier to identify when taking deep breaths immediately after exercise.
Rika also listened to her own heartbeat and noticed that her heart rate was slowing down quickly, saying, "It might be regulating faster!"
Finally, when we had him sit on the bed and then lie down, he became incredibly slow, making a "dock, dock, dock" sound, as if he might stop altogether. After a while, he returned to his normal speed.
When I compressed her chest, I could clearly hear her heartbeat. By firmly pressing her slender chest against the wall with my hands, I could hear her heart beating very clearly, and it made me realize once again that even in Rika's thin body, there is a heart inside and beating strongly. I performed the compressions a total of three times.
During the compression, Rika closed her eyes and endured it, and her heartbeat gradually quickened. Especially during the second compression, Rika's body swayed in time with her heartbeat. Even after the compression was released, her heartbeat remained fast for a while, indicating the intensity of the strain. This shows just how powerful the compression was.
Finally, when I brought the camera closer to her chest and applied pressure, I could see my hand twitching in response to Rika's heartbeat.
When we looked at the electrocardiogram and listened to the heart sounds on the electrocardiograph, we attached electrodes to Rika, who was lying down, and the waveform appeared in time with her heartbeat. The waveform was clean and the rhythm was good, but when we checked her heart rate, it was a surprisingly low 56 BPM, which is on the slower side. This might be because she was lying down, but it's still quite slow. Rika was momentarily confused, saying "56?", and when we showed her the average heart rate for women, she was surprised at how extremely slow her heart rate was, and her heart rate increased slightly at that point.
When you stretch, your heart rate jumps up to 70 BPM, and the electrocardiograph is clearly capturing the changes in your heart's activity.
Next, when we asked the patient to take deep breaths, there was a significant difference in heart rate between inhaling and exhaling, with some heart rates dropping below 60 BPM during exhalation. Looking at this, it's clear that respiratory arrhythmia is present.
Finally, I asked them to hold their breath.
When you hold your breath for one minute, your heart rate will be faster at first, but it will gradually slow down. When the timer goes off and you resume breathing, your heart rate will also be slightly faster.
She still seemed to have plenty of energy left, so we filmed her holding her breath for two minutes in a separate video. She looked like she was struggling, but she did her best to hold it. Rika seemed to be good at holding her breath, so we asked her to hold it to her limit one more time, and she managed to hold it for a considerable 2 minutes and 20 seconds. Towards the end, she was frowning and had a strained expression, pushing herself to the absolute limit, and her efforts paid off as she was extremely out of breath when she resumed breathing. I would love for you to see her heart rate at that time.
The electrocardiogram and heart sounds recorded while exercising with the bag over her head showed that her heart rate was initially a slow 56 BPM, but it gradually increased as she performed leg raises and breathed inside the sealed bag. The bag expanded and contracted in time with Rika's breathing, creating a tight seal.
Partway through, they kept saying "This is too hard!" and eventually stopped exercising because it was too difficult.
At that time, her heart rate was 85 BPM, which is quite fast for Rika, and her oxygen saturation level had dropped to around 91, indicating that she was consuming a significant amount of oxygen.
The patient raised their hand at this point, and when the bag was removed, they began breathing deeply, saying "Oxygen! Oxygen!" However, their oxygen saturation level did not improve immediately; in fact, it dropped further to 81. It seems their body is not keeping up with supplying oxygen.
After breathing for a while, the reading returned to 99.
With the echocardiogram and heart sounds, the heart, beating at approximately 58 BPM, can be seen moving in the upper right corner of the screen when the probe is applied. It's a little hard to see, but the movement of a bradycardia is extremely slow, so slow that it looks like it might stop at any moment. It's amazing that the heart can still circulate blood even with such slow movements.
Seeing their own heart for the first time, they are fascinated, exclaiming, "It's beating!" and "It's working so well!"
When you take a deep breath to hold your breath, your lungs expand and your heart is hidden, but when you resume breathing, your heart becomes visible again, and its movement is faster and seems larger than before.
This time, we performed an echocardiogram immediately after the patient performed step-up exercises.
The time spent stepping up and down is relatively short, only about a minute, but even so, the heartbeat is fast immediately after it finishes, and when the probe is applied, the movement is faster than before, and the heartbeat is also easier to see.
Rika also commented, "I can see better than before," and "It's so fast!"
Finally, after taking a deep breath, the patient's heartbeat gradually became quieter and their movements slowed down.
The ultrasound images are also available in a separate video.
The sound of her heartbeat during masturbation was recorded while she was completely naked.
Having taken off your swimsuit completely, your slender figure is even more emphasized, and you look absolutely beautiful.
There are some scenes where the camera's shadow is visible due to the lighting, but that actually enhances the eroticism.
As we inserted the adult toys and attached the vibrator, she involuntarily let out a moan, and throughout the act, she occasionally said, "It feels good." Her facial expression during the act was also incredibly erotic, and as she reached orgasm, she softly said, "Ah, I'm coming..." and her body twitched. Moreover, her orgasm lasted for nearly a minute, which was longer than that of the other models.
As for the crucial sound of her heart, Rika's heart gradually quickens as she masturbates, presumably because she is feeling pleasure. It slows down for a moment, but then quickly speeds up again, and as she climaxes, it beats incredibly fast, even faster than when she was feeling pleasure, and the pulse becomes extremely strong, indicating she is having a real orgasm.
Even without watching the video, you can tell the difference in when the heartbeat is reaching its peak just by listening to it.
Even though you have a tendency towards bradycardia, I was relieved to see that your heart rate quickened properly when you reached your goal.
