Other Causes of Elevated Heart Rate. Elevated heart rate when sick is actually your heartâs aid in order to quell the sickness. However, there can be other causes for elevated heart rate as well. Electrical signals produced and sent to the heart tissues are responsible for controlling the heart rate.
A pulse rate faster than 100 beats per minute is called tachycardia. Conditions such as congestive heart failure (CHF), hemorrhage, shock, dehydration, and anemia can all speed up the heart rate.. If the pulse is regular, count for 30 seconds, then multiply that number by 2.If the pulse is irregular, count for 1 full minute. View poster preview. Palpate a patient's pulse to determine circulation distal to the pulse site and for rhythm, quality, and strength.
