What is the implication if the heart rate is below on above the normal rate?

If the heart rate is below the normal range (bradycardia), it can indicate potential issues such as heart block, electrolyte imbalances, or the effects of certain medications, potentially leading to fatigue, dizziness, or fainting. Conversely, a heart rate above the normal range (tachycardia) may suggest stress, anxiety, dehydration, or underlying health conditions like hyperthyroidism or Heart disease, which can increase the risk of heart complications. Both conditions warrant further evaluation to determine the underlying cause and appropriate management.
