Question

What is the normal heart rate, and what is considered an abnormal heart rate?

a) The normal heart rate is 60-100 beats per minute, and anything below or above this range is considered abnormal.
b) The normal heart rate is 120 beats per minute, and anything lower is considered abnormal.
c) The normal heart rate is 30-50 beats per minute, and anything higher is considered abnormal.
d) The normal heart rate varies widely and is not defined.

Answer 1

The standard adult resting heart rate ranges from 60-100 bpm. Rates below or above this are considered bradycardia and tachycardia, respectively, and can be significant if symptomatic.

Step-by-step explanation:

The normal heart rate for an adult at rest is typically in the range of 60-100 beats per minute (bpm). A heart rate below this range (bradycardia) is usually considered abnormal, potentially indicative of a health concern if accompanied by symptoms such as weakness or dizziness. A heart rate above 100 bpm while at rest (tachycardia) is also considered abnormal and may be caused by various factors including stress, illness, or certain medical conditions. Specific conditions such as arrhythmia can represent heartbeats that are irregular, too slow, or too fast, leading to potential complications. Treatment and significance depend on underlying causes and accompanying symptoms.
