Is It Normal To Have Heart Rate Of 40bpm During Sleep?

Posted on Wed, 27 May 2015

Question: I had all cardiac testing done 2 months ago. Everything came back structurally normal with my heart. I have pacs and rare pvcs according to my holter monitor. I passed my stress test. My holter was always in sinus rythm. Something that worries me is the fact that my resting heart rate sometimes goes to 55 bpm. My cardiologist says there is no heart block and no SSS. He says my heart is normal and I am healthy. This scares me. Is this normal? During sleep my bpm went down to 41. My 48 hour holter said 26 % of the time in bradycardia and 13 % tachycardia. My cardiologist says this is all normal. Is this a common finding? I know my cardiologist says these are benign. I was just wondering if it's dangerous to wake up with the erratic heart beats. Also is it normal to get more etopic before bed and do they occur during sleep

Brief Answer:
Following answer to your query.

Detailed Answer:
Hi XXXXX!

You shouldn't worry about your heart its perfectly normal (as shown from cardiac examinations ).

You have a resting heart rate that go as low as 55 bpm. This is very common and no need to worry about it.

Also you have a minimal heart rate of 40 bpm during sleep that is normal to. All the other findings especially the percentage of periods of bradycardia and tachycardia are normal to.

It's a normal thing to experience palpitations at night before sleep (due to night quietness) and in the morning (due to adrenaline peak release).

Hope this was of help!
Wish you health!
