Tachycardia specifically refers to an abnormally fast heart rate, which is typically defined as a resting heart rate over 100 beats per minute in adults. This condition can result from various factors such as exercise, stress, anemia, fever, or various medical conditions. It indicates that the heart is beating faster than normal and may require further evaluation to determine the underlying cause.

Understanding tachycardia is crucial in emergency medical situations as it can be a symptom of serious health issues, including cardiac distress, and can lead to complications if not addressed. Recognizing this condition is essential for EMTs and medical professionals when assessing a patient's cardiovascular health and overall stability. Other options refer to different medical conditions and physiological responses, but they do not accurately define tachycardia.
