Antibiotics are used to treat or prevent some types of bacterial infections. They aren't effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat conditions:
1 A normal adult resting heart beat is between 60-100 heartbeats per minute. 2  Some experienced athletes may see their resting heartrate fall below 60 beats per minute. 3  Tachycardia refers to the heart beating too fast at rest-over 100 beats per minute.
For most adults, normal heart rate is 60 to 80 BPM. Well-trained athletes can have a normal heart rate of 40 to 60 BPM. When you work out, your heart rate will get higher. This is called your active heart rate. Active heart rates, like resting heart rates, differ in people and change as you age. Generally, a healthy active heart rate is 60 to 80 percent of your maximum heart rate, or the highest your heart rate should safely go.
