I had a terrible panic attack Christmas eve and even though my EKG/xray and all the blood work came back normal the doctor said he'd feel more comfortable if I was on some blood pressure meds until speaking with my GP and talking to a cardiologist because people my age have had cardiac damage from covid. While I didn't think I needed it I've been taking it for 4 days and feel generally more calm and it seems to cap my racing heart at just "slightly high" and not "sit down before you pass out"
