Answer: (C)

Tachycardia refers to a condition in which an individual has a rapid heart rate, generally defined as a resting heart rate exceeding 100 beats per minute in adults. This increased heart rate can occur during exercise, as a response to emotional stress, or may indicate underlying health issues such as fever, anemia, or heart conditions. Understanding tachycardia is crucial in the field of emergency medical services, as it may require further assessment and intervention depending on the patient's overall condition and symptoms. Recognizing the characteristics and implications of tachycardia allows providers to recognize when urgent medical actions may be needed.
