I'm noticing that my heart rate is going above 100-115 from time to time. My blood pressure is normal, but my hemoglobin level is 10.8. About a month ago, I had an ECG done, and it showed sinus tachycardia and IRBBB. But I'm still experiencing a heart rate over 100-115. Should I be worried about this? What might be causing it?
