I am on Budecort 200mcg inhaler , 2 puffs twice daily since 1 year because of asthma. Since 7-8 months while checking on oximeter, I always find my heart rate almost always above 100 and upto 130. Even in resting condition. Sometimes I even feel sort of palpitations or fluttering in my chest, which happens around twice in a week , and it then subsides within 10 minutes. At times, I get breathless even without doing any exercise. After waking up from sleep, the heart rate is generally around 90. Oxygen levels are always normal. What steps can be taken ?
