Do you know what they checked specifically? There are many things that can cause an elevated resting heart rate such as thyroid issues and anaemia. Or it might be related to any medication you take or things like caffeine / alcohol consumption. In my experience doctors generally don't worry too much if you're only just outside of normal ranges, but that doesn't mean something isn't wrong / suboptimal with your health. I'm not blaming doctors for this, at the end of the day they only have so much time and they can't waste time trying to obsessively optimise the health markers of every person they see. But that doesn't mean you can't. For example, hyperthyroidism can cause both panic attacks and a high resting heart rate. Even if your doctor tested you for hyperthyroidism it's still worth knowing if you're own labs because like I say, if they're only slightly high your doctor is quite likely to overlook it as it's not an immediate risk to your health, but slightly high can still cause problems for some individuals. Personally a high resting heart rate is something I'd be very concerned about because it will take years off your life. You really want it in the low normal range of around 60-70bpm.
