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.
Without nervous system control, your heart would beat around 100 times per minute. However, when you are relaxed, your parasympathetic nervous system sets a resting heart beat rate of about 70 beats per minute, (resting heart rate is usually between 72-80 beats per minute in women and 64-72 beats per minute in men).0-100 beats per minute is the normal range for healthy adults. Count for a full minute during different times of the day as your heartrate fluctuates with activity, anxiety/stress and even the time of day.
