What Causes A High Pulse Rate?
Thank you for contacting XXXXXXX
A pulse rate of 111 per minute is slightly high. Normal pulse rate should be between 60 to 100 beats per minute. Average normal pulse rate is 72 per minute. However, pulse rate may go up normally after exercise; or when one is anxious; or during fever. When there is no obvious reason for increased pulse rate, hyperthyroidism (excess thyroid hormones) should be excluded (a blood test for T3,T4 and TSH is sufficient to exclude this condition). Rarely, rhythm abnormalities of the heart may cause increased pulse rate. But in this case, one should have palpitaitons (uncomfortable awareness of one's own heart beats).
However, if you do not have any symptoms, please keep a regular watch on your pulse rate. If it remains high for some days, you may go for above evaluations (thyroid profile blood test and an ECG).
Please get back if you have any more queries.
