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.
a normal resting heart rate for adults ranges from 60 to 100 beats a minute generally a lower heart rate at rest implies more efficient heart function and better cardiovascular fitnessfor example a well trained athlete might have a normal resting heart rate closer to 40 beats a minute normal resting heart rate for adults ranges from 60 to 100 beats a minute generally a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness
