What is a spectrometer? A spectrometer is an tool commonly used by astronomers which splits the light collected by a telescope into its colors. This allows astronomers see the details in the light from space. Astronomers know how to get a lot of special information about a space object by studying its light. By using spectrometers, we can find out the temperature of an object in space, learn which direction it is traveling, find out how fast it is going, figure out its weight and even find out what it is made of.
Negative inotropes weaken the heart's contractions and slow the heart rate. These medicines are used to treat high blood pressure (hypertension), chronic heart failure, abnormal heart rhythms (arrhythmias), and chest pain (angina).
Some people become very short of breath or dizzy when their heart rate speeds up. Getting the heart rate to slow down can help eliminate those problems. Cardioversion is also performed when someoneâs heart rate becomes irregular, such as atrial fibrillation or atrial flutter. If the heart remains in one of these rhythms for a long time without taking a blood thinning medication, you could be at risk for having a stroke.
