Differential Diagnosis. The diagnosis of spondylolysis is confirmed by the discovery of a pars defect on a lateral x-ray or CT scan, and spondylolisthesis is confirmed by noting the forward position of one vertebral body on another.
A normal resting heart rate for adults ranges from 60 to 100 beats a minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.
Itâs best to measure your resting heart rate it in the morning before you get out of bed, according to the American Heart Association (AHA). For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the personâs physical condition and age. For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm, according to the AHA. But a heart rate lower than 60 doesnât necessarily mean you have a medical problem. Active people often have lower heart rates because their heart muscles don't need to work as hard to maintain a steady beat. Athletes and people who are very fit can have resting heat rate of 40 bpm.
