Suggest Treatment For Fluctuating Heart Rate

I am worried about my resting heart rate.
In bed at night it is btw 40-50 bpm sometimes even in the 30's.
I am 37 years old, slim build. I do cardio exercise everyday e.g run, cycle, aerobic classes. At peak exercise it ranges between 140-170bpm. However I am not an athlete!
I have become obsessed with checking my pulse because of a new heart rate ap I have ( not a great idea now for me!)
My question is will I need a pacemaker later on in life and is this infact to low? Will I benefit on cutting down on my cardio exersion?
Normal, accetable figures
Detailed Answer:
Hello, madame! Thank you for your question and welcome to HCM. I am Dr. Meriton and carefully read your query.
Heart rate is a variable component in everyday life. It is subject to a lot of physiogical changes happening to our bodies during a day. And I am referring to physical activity, psychological stress and hormonal level peak and nadirs during a day. Now, everyone's heart races when they exercise, and there is a formula for that, 220 - age. So, in your case, during physical activity, the heart rate is expected and normal to go up to 183 beats per minute, so my opinion is that there is nothing to worry about and no further treatment is recommended, having also in mind that you mentioned you had benign premature ventricular beats and sinus tachycardia. As for the other part, in people who jave moderate to vigorous, or have regular, physical activity, the accepted heart rate as normal is down to 45 beats per minute. During sleep, there is a predominance of the parasympathetic system in the human organism, which, among others, lowers the heart rate. I would not worry about this problem either. However, if this comes as a constantly worrisome event to you, you can wear a 24-hour Holter rhythm monitor, which registers your heart rate figures spun in 24-hours. Whether you will need pacemaker or not, in the future, cannot be predicted now, since I do not see any pathological condition or abnormality in your case. Physical activity is a very healthy behaviour and recommended to everyone. I think that you should continue to engage to physical activity, as you scheduled according to your lifestyle.
I hope this answers your concerns. If you have follow-up queries, I would be happy to help. I wish you a good health.
Best regards,
Dr. Meriton
