What condition is characterized by an increased heart rate?

Tachycardia is defined as an increased heart rate, typically exceeding 100 beats per minute in adults. This condition may arise due to various factors, including stress, anxiety, fever, anemia, heart conditions, or the effects of stimulants. Understanding tachycardia is essential in the context of health assessments, as it can indicate underlying health issues that may require further investigation or intervention.

Bradycardia, on the other hand, refers to a slower-than-normal heart rate, making it the opposite of tachycardia. Hypertension is characterized by elevated blood pressure levels and does not specifically relate to heart rate. Similarly, hypotension refers to low blood pressure, which also does not correlate directly with an increased heart rate. These distinctions are crucial in differentiating cardiovascular conditions and understanding their implications for patient care.
