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).
Problems with this electrical conduction system can cause an arrhythmia. Arrhythmias can cause the heart to pump less effectively because the coordination of the heart muscle becomes uncoordinated. Certain arrhythmias increase your risk of other medical problems like stroke or blood clots. In an arrhythmia, abnormal electrical signals through the heart muscle may cause the heart to beat too fast, too slow, or in an irregular manner. In any of these situations, the heart may not be able to pump an adequate amount of blood to the body with each beat.
