Anxiety, heavy exercise, pregnancy and chronic kidney disease can cause an increased pulse rate, states MedlinePlus. Abnormal heart rhythms, hyperthyroidism, anemia and fever can also cause an increased heart rate.

Other factors that can affect heart rate include air temperature, humidity and certain medications, reports the American Heart Association.

Patients should contact a doctor if their pulse rate suddenly increases and does not go away, states MedlinePlus. It is especially important to contact a doctor for those who already have heart conditions. The National Heart Association also stresses the need to contact a doctor if the increased heart is accompanied by dizziness, fainting or weakness.

For adults and children 10 years and older, the average resting heart rate is between 60 and 100 beats per minute, states the American Heart Association. Athletes tend to have lower resting heart rates, ranging from 40 to 60 beats per minute. While doing heavy exercise, the heart rate increases to around 70 to 90 percent of the maximum heart rate. The maximum heart rate for people in their 20s is 200 beats per minute, while the maximum heart rate for those in their 50s is 165 to 170 beats per minute.

To check heart rate, place a finger over the pulse and count the number of beats within one minute, explains the American Heart Association. The best places to find the pulse are the wrists, the top of the foot, the inside of elbow and the side of neck.
