When should I worry about bradycardia - low heart rate?

What is a normal heart rate?

A normal heart rate is anything between 60 and 100 beats per minute (bpm). Anything that falls below 60 bpm is considered a low heart rate, which doctors call ‘bradycardia’.

It’s normal for your heart rate to vary during the day. This is because it’s affected by daily activities like exercise and the food you’ve eaten. As a result, your heart rate may drop below 60 bpm at some points and then speed up again.

What if my heart rate is too low?

It’s also common for your heart rate to drop below 60 bpm when you’re asleep. This is because your body processes slow down meaning the heart does not need to work as hard. But it will usually go back to normal when you wake up.

Some people have a naturally low heart rate or a health condition that affect their heart’s ability to regulate its rhythm. A low heart rate can also develop as you age.

If you’re usually fit and healthy, and you do not have any symptoms, then try not to worry if your heart rate drops below 60 bpm.

But speak to your doctor if you notice new symptoms that can be associated with bradycardia, like:

• dizziness
• palpitations
• feeling more tired than usual
• feeling generally weaker and fainting.

They will be able to discuss the need for any further tests, investigations or treatments with you.
