What Causes Fluctuations In Heart Rate?
Question: My pulse is slower than usual. My resting heart rate is usually between 80-100 but is typically in the 90s. And when I'm standing it's usually in the 110s. At the moment it's between 55-62 and it was even as low as 52. It's not even reaching 70 when I stand. What might be causing this?
Brief Answer:
Physiological fluctuations
Detailed Answer:
Hello and welcome to HCM. I understand your concern. Thank you for your question.
I will start my answer by informing you that the normal heart rate figures are between 60 and 100 beats per minute. In various physiological situations and/or other factors, such as position changing, day-night cycle etc., these figures may be increased or decreased and still considered normal. This being said, we have to add the fact that you are young, only 26 years of age.
Now, heart rate is mostly individual, where some of the people may have a normal heart rate of 90 beats per minute. This is their mean heart rate. But, in resting states, such as when one is lying down or during sleep, the resting heart rate may go down to 50 beats per minute, even 45 is considered normal. Also, sudden changes in one's position such as from sitting to standing up and vice-versa, there may be increased/decreased heart rate due to the abrupt re-distribution of the blood circulation. With all these being said, I would like to put your mind in peace, and reassure you that there is nothing to be worried about. I would not recommend any further treatment or other procedures.
I hope I have been of help. I am happy to help, if you have follow-up questions.
Best regards,
Dr. Meriton

My resting heart rate is usually around 90. I have monitored it for a few years for fitness. I know it's rarely lower than 80, so 60 is low for me. Could the iron supplements I'm taking be contributing to the lower readings?
Brief Answer:
No contribute
Detailed Answer:
Hello and welcome back.
There is no contribute of iron supplements to the fluctuating of heart rate. Major contributors of this phenomenon are changes that come from various physiological situations, which I described in my original answer, and they happen to everyone, including me. It is just that some people pay more attention to this, and then it is accompanied with stress and anxiety, which may pronounce these fluctuations. My recommendation is that you have nothing to be worried about and that you are a healthy, young woman.
I hope my follow-up is helpful. If you do not have further questions, please close the discussion and rate the service.
Kind regards,
