Riona's heartbeat 2

* This work is fictional, and all persons appearing in it were 18 years of age or older and were filmed with their consent.

Thank you for viewing.
This is Riona's heartbeat, age 23 (part 2).
She was a tall model at 165 cm, with a large F-cup bust and beautiful, fair skin. She was fair-skinned, cute, and had a large bust—the perfect combination.
During the shoot, you were very considerate of things like camera angles, and I had such a great time that the time flew by.
Furthermore, Riona had participated in various sports such as dancing and swimming, which seemed to have strengthened her heart, resulting in a very slow heartbeat. When counting her resting heart rate, it was sometimes below 50 BPM, indicating a significant tendency towards bradycardia, which was also evident from her heart sounds, even at heart sound level 2.
The contents are
- Heartbeat sounds when standing and when bending over
- Heartbeat sounds during leg raises
• Various blood pressure readings and heart sounds
- Heartbeat when lying down
- The heart when chest is compressed after exercise
- Heartbeat sounds when breathing in a bag
- Heart sounds while holding in urine and while urinating
- Heartbeat sounds during sexual activity (full nude version)
That is the case.
The video is 35 minutes and 16 seconds long in total.

Regarding the heart sounds while standing and while bending, this was the first time you heard my heart sounds while standing during this photo shoot.
Many models have a faster heartbeat when standing, but in Riona's case, there isn't much difference compared to when she's sitting. It was slow when she was sitting, so I'm surprised it's not much different when she's standing.
Riona also said, "It doesn't seem to have changed much," but when she squatted down to do some stretching exercises, her heartbeat slowed down even further, as she said, "Has it gotten slower?" When she stood up again, it became faster, and the difference was clearly noticeable.

For the leg-raising exercise, we ask you to perform three sets of 10 repetitions to measure your heart rate.
Before starting, Riona's heartbeat was slow, but after just 10 leg raises, it started beating faster, and she exclaimed, "It's fast!" After the 10 reps, there was a 10-second interval during which her heartbeat calmed down, but as soon as she started the next 10 reps, it started beating fast again. Riona's heart is certainly very busy!
After the third set, they said, "That was tough..."

Blood pressure and heart sounds are measured both while lying down and sitting.
When she had her blood pressure measured at the hospital about a month before the photoshoot, she was told that nothing was wrong and that there were no abnormalities. However, when we actually measured it, it was a little lower than the average for women in their 20s, and when Riona took a look, she said, "You have low blood pressure!" What's also concerning is her heart rate, which is still very low, below 50 BPM, and that's what really catches the eye.
While sitting, my systolic blood pressure remained unchanged, but my diastolic blood pressure increased slightly.
Your heart rate has also increased slightly, but it's still on the lower side.

When she lay down, her heart rate was slow, about the same as when we measured her blood pressure earlier. We had her stretch a few times. For the first two stretches, the speed didn't change much, but when she stretched a little deeper, Riona said it "didn't change much," but it seemed to have gotten a little faster.
Even when she stretches, Riona's heart doesn't seem to be affected much.
When he finally stood up, his heart rate had increased noticeably, and he exclaimed, "It's gotten faster!"

When I compressed her chest after exercise, her heart rate was very fast when she did step-ups, with a "thump, thump, thump, thump" sound. When I compressed her chest, it was much faster than when I compressed it at rest, with a heart rate of around 130 BPM. I could feel her ventricles contracting with each beat, pumping blood into the aorta with all her might. The exercise and compressions made her cute face contort in pain, and she was breathing heavily, "ha, ha, ha," which was a very welcome reward as her breath blew onto my face.
Also, Riona, who isn't wearing earphones, seems to be able to hear her own heartbeat, and she whispered, "I can hear it so clearly!"
The heartbeat gradually calmed down, and when the pressure was released, the heartbeat slowed even more, so I tried applying pressure again.
After the shoot, I collapsed onto the bed, completely exhausted, so I also recorded my heartbeat at that time. My heart rate was slow, but it was slightly stronger than when I was lying down earlier. Also, when I measured my blood pressure in this state, my systolic blood pressure was slightly elevated.

The heart sounds recorded during bag breathing were taken while the subject was in a resting state, breathing in a sealed bag over their head.
Occasionally, the patient takes deep breaths to try and replenish the dwindling oxygen levels. Initially, the oxygen saturation level decreases gradually, but then it drops sharply, reaching a low of 86.
It seems that the oxygen in her body was consumed very rapidly, which shows that Riona also consumes oxygen to survive.
Furthermore, the heart rate increased from a slow 51 BPM to 74 BPM, indicating that the heart rate increased to efficiently circulate the reduced oxygen.
His breathing had become rapid, and he looked quite distressed, saying he was at his limit. When the bag was removed, his oxygen saturation had returned to 93, and upon seeing that number, the doctor said, "It's dropped quite a bit!"

The heart sounds during and after urination indicate that the patient needs to go to the toilet, so we are asking them to hold it in for a little while before urinating.
I have them stand in front of the toilet and ask questions like, "How long have you been holding it in?" or "How many times a day do you go to the toilet?" I tease them by not letting them urinate, and they glance at the toilet bowl occasionally, looking like they want to go quickly.
When I press on her lower abdomen, she desperately resists, saying, "Ahhh, not there!", "No, no, no, I'm going to leak!", and her heart rate increases.
I asked her to urinate, but she stopped after only letting out a little. She looked distressed and said, "I don't think I can do it!", but she couldn't stop and kept saying, "No!", "I can't stop, I can't stop!", and in the end she let it all out.
My heart was beating fast at that time, and I was feeling quite desperate.

Finally, I was allowed to hear the beat of her heart as she performed sexual acts while fully nude.
When Riona, who is completely naked, has adult toys applied to her sensitive areas, it's easy to see the changes, such as her heart rate quickening or calming down.
It seems you can really feel the difference in the parts where the speed increases.
Finally, she said "I'm coming!" and lifted her hips as she reached orgasm.
