Uranus at opposition is just barely visible to the naked eye and was undoubtedly seen by the ancients. But it moves very slowly, about four degrees per year, so that its motion is not readily apparent. With no special reason to watch this particular dim star over the course of several months, none of the ancient records identify it as a planet.
Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat directly (auscultation), traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers.
Heart rate is measured by finding the pulse of the heart. This pulse rate can be found at any point on the body where the artery's pulsation is transmitted to the surface by pressuring it with the index and middle fingers; often it is compressed against an underlying structure like bone.
