Isthmic spondylolisthesis is caused by a defect in a part of the vertebra called the pars interarticularis. This defect can cause the vertebra to slip forward.
What's a normal heart rate? Most adults have a resting heart rate of 60-100 beats per minute (bpm). The fitter you are, the lower your resting heart rate is likely to be. For example, athletes may have a resting heart rate of 40-60 bpm or lower. You should contact your GP if you think your heart rate is continuously above 120 bpm or below 40 bpm, although this could just be normal for you.
The normal resting heart rate for an adult is between 60 and 100. The typical healthy resting heart rate in adults is 60-80 bpm, with rates below 60 bpm referred to as bradycardia, and rates above 100 bpm referred to as tachycardia. Note howâ¦ever that conditioned athletes often have resting heart rates below 60 bpm. 70-75 beats a minute.
