is the rate at which the heart is beating and is measured by listening to the sounds of the heart with a stethoscope or by ECG. Pulse rate is the rate at which the pulse is felt at different places in the body, commonly at the wrist. The pulse rate can never be higher than the heart rate. However, at times, the heart rate can be higher, as occurs during certain arrhythmias where each heart beat does not translate to a pulse wave.
Your main complaint is postural dizziness
. Though there could be many causes, certain corrective measures can be taken. Always keep yourself well hydrated. Drink lots of fluids, and take a little extra salt in the diet. Avoid sudden standing from a lying down position. Jerk your legs a few times in the lying down position, then sit up, dangle your legs down and bend and straighten a few times. Slowly stand up and stamp a few times. You could also consider wearing stockings. If these measures dont help, you should see a physician for further evaluation.
