Hello and welcome to the forum. Thanks for your question. We, of course, can not diagnose you and hopefully you will sit down with your doctor to discuss these results. Bradycardia as suggested is something to confirm with your doctor. This is when your resting heart rate is below the average and not because you are a world class competitive athlete. For some people, it is not a serious issue and has no symptoms or complications. Others, it is more serious and they may require a pacemaker. If you have bradycardia, your doctor will want to try to uncover the underlying cause to treat it. There are many reasons why it can occur. https://www.mayoclinic.org/diseases-conditions/bradycardia/symptoms-causes/syc-20355474
When do you follow up with your doctor next?
Hmmm.. yeah 43 is actually quite reasonably Bradycardic. Do you faint or feel like fainting frequently?
You may actually need a Pacemaker this much is true.
Thankfully for you they make leadless devices that are wireless and easy to insert. You won’t have any scars or realize it’s there and can usually go home just a few hours after implant; next day at the latest.
