What is a one-sentence summary of the following article?
. The first step in estimating your systolic blood pressure is to locate your pulse. Your pulse will give you basic information you need to estimate if your systolic blood pressure is relatively normal. Keep in mind this is a very rough estimate and really only tells you if your systolic blood pressure is not low — it doesn't indicate high blood pressure.  Take two fingers, preferably your index and middle fingers, and place them just below the wrist creases on the thumb side of your hand. Don't use your thumb, as your thumb has a strong enough pulse to interfere with this process. Once you’ve got your two fingers in the general area, see if you can feel your radial pulse – the shockwave generated by the beating of your heart. If you feel your pulse, this indicates that your systolic measurement is at least 80 mmHg, which is normal. This does not, however, give you any information as to whether or not your blood pressure is high. If you don’t feel your pulse, your systolic is likely below 80 mmHg, which is still normal.  The reason this indicates your blood pressure is at least 80 mmHg is because your radial artery (the artery in your wrist) is small and your blood pressure has to be at least 80 mmHg for a pulse to reach it.  Not feeling your pulse does not indicate health problems. Estimating your blood pressure without a cuff will give you no information about your diastolic pressure. Some studies have questioned the efficacy of estimating systolic pressure using your pulse. You should recheck your pulse later in the day to get an idea of how your pulse increases after some activity. This will give you more information to determine whether your blood pressure is low, high, or normal.  If you don’t have a detectable pulse after moderate activity, there is a chance you could have low blood pressured. Consult your doctor if you suspect any irregularities.

Summary:
Place your fingers on the inside of your wrist Notice your pulse. Recheck your pulse after you’ve been moderately active.
