Example 10: 56 (8)y The number 56 is positive and the number 8 is negative. These numbers have different signs.
Taking a Pulse (Heart Rate) Your pulse is the rate at which your heart beats. As your heart pumps blood through your body, you can feel a pulsing in some of the blood vessels close to the skin's surface. The usual resting pulse for an adult is 60 to 100 beats per minute. Certain illnesses can cause your pulse to change, so it is helpful to know what your resting pulse is when you are well.
Resting heart rate, or pulse, refers to the number of times your heart beats per minute when you are at rest. Though a normal range is 50 to 100, most peopleâs hearts beat 60 to 80 times a minute. Above 100 is considered a rapid pulse, called tachycardia; an unusually slow resting heart rate is called bradycardia.or example, if you are 50, your maximum heart rate is 220 minus 50, or 170. Then multiply 170 by 0.6 (for the low end) and by 0.8 (for the high end), which gives a range of 102 to 136. Your heart rate should fall between these two numbers while you exercise.
