Why each option
Tachycardia is the clinical term for a heart rate exceeding 100 beats per minute, indicating a fast rhythm that may be physiological or require medical evaluation.
A heart rate below 60 bpm defines bradycardia, which is the opposite dysrhythmia from tachycardia.
A heart rate greater than 100 beats per minute is the standard clinical criterion for tachycardia. This threshold is applied universally across cardiology and emergency medicine to identify abnormally fast rhythms, which can arise from physiological stimuli such as exercise and fever or from pathological causes such as supraventricular or ventricular arrhythmias.
A heart rate of 70-80 bpm is a normal adult resting rate and represents neither bradycardia nor tachycardia.
A heart rate of 90-100 bpm is within the high-normal range and does not meet the greater-than-100 bpm threshold required for a tachycardia designation.
