I'm really concerned about my heart rate because it's usually around 100 or more whether I'm just sitting, walking, or doing anything else. I've been using my Fitbit to track it, and I also have an Omron BP machine at home that often shows it going over 100, sometimes even hitting 120. I did see a cardiologist who said it was nothing, but I'm still worried. Can you help me figure out what might be going on or if there's anything I should do?
It sounds like you may be experiencing persistent tachycardia. One common medication used to help lower heart rate is Metoprolol (brand name: Lopressor). I recommend discussing with your doctor about starting Metoprolol at a low dose, such as 25mg once daily, and then adjusting the dose as needed to help control your heart rate. It is important to monitor your blood pressure and heart rate regularly while on this medication.
