Step-by-step explanation:
The technical term for an abnormally rapid heart rate is tachycardia. Normalizing heart rhythm is crucial when dealing with arrhythmias, which can manifest as either too fast, known as tachycardia, or too slow, known as bradycardia. Tachycardia occurs when the heartbeat is above 100 beats per minute in adults, while bradycardia is when it's below 60 beats per minute. It's important to note that factors like exercise, stress, and certain medical conditions can cause fluctuations in heart rate. Treatment for tachycardia depends on the underlying cause and may encompass medications, implantable cardioverter defibrillators, ablation, or surgery.
