What does a “heart rate 53” mean when you’re taking Lyrica (pregabalin)?
A resting heart rate of 53 beats per minute (bpm) is typically considered “bradycardia” only if it is low for you and/or comes with symptoms. Many people naturally run in the low 50s, especially if they’re fit or the number is taken during sleep or rest. The key question is whether the low heart rate is causing problems (dizziness, fainting, chest pain, unusual shortness of breath, confusion).
Lyrica (pregabalin) is not commonly known for directly lowering heart rate in the way some blood pressure or rhythm medications do. Still, any medication can contribute indirectly through side effects such as dizziness, sedation, or blood-pressure changes that make bradycardia feel worse—even if the heart rate itself doesn’t drop substantially.
Could Lyrica cause a low heart rate or worsen bradycardia?
Lyrica can cause side effects that overlap with symptoms people notice when heart rate is low, including dizziness and sleepiness. If your Lyrica dose is new, increased, or combined with other medicines that slow heart rate (for example, beta-blockers like metoprolol or bisoprolol, some calcium-channel blockers like verapamil or diltiazem, certain antiarrhythmics, or some sedatives), the combination can make a low resting heart rate more concerning even if Lyrica isn’t the primary cause.
If you’re seeing a trend (heart rate dropping after starting or increasing Lyrica), it’s worth discussing with the clinician who prescribed it.
When is a heart rate of 53 on Lyrica an emergency?
Seek urgent care or call emergency services if heart rate 53 comes with any of these:
- Fainting or near-fainting
- Severe dizziness or inability to stay awake
- Chest pain
- Shortness of breath at rest
- Confusion, trouble speaking, or new weakness
- Heart rate repeatedly much lower (for example, <40 bpm), or accompanied by a feeling that your heart is “pausing”
If you feel well, it’s usually reasonable to document the readings (time of day, symptoms, whether you were sleeping/resting) and contact your prescriber soon.
What should you do right now if your HR is 53?
- Check whether the reading is real and repeatable: recheck after sitting quietly for 5 minutes.
- Note symptoms: dizziness, lightheadedness, weakness, chest discomfort, or faintness.
- Review meds and timing: did Lyrica start or dose change recently? Are you also taking any heart-rate–slowing drugs or sedatives?
- Don’t stop Lyrica suddenly on your own. If dose adjustment is needed, a clinician should guide the taper/plan.
What questions to ask your doctor about Lyrica + bradycardia?
Bring the following details:
- Current Lyrica dose and when you started or increased it
- Your typical heart rate before Lyrica
- Whether the 53 bpm occurred while awake or asleep
- Any other symptoms (dizziness, fatigue, fainting, chest symptoms)
- Other medications (especially beta-blockers, calcium-channel blockers, antiarrhythmics, opioids, and sleep meds)
Your clinician may consider an ECG and review medication interactions or causes such as conduction disease, dehydration/electrolyte issues, thyroid problems, or recovery after illness.
