Tachycardia is defined as an elevated heart rate that exceeds the normal resting rate for adults, which typically ranges from 60 to 100 beats per minute. When a heart rate is more than 100 beats per minute, it is classified as tachycardic. This condition can be indicative of various physiological responses or medical conditions, such as stress, fever, anemia, or heart disease. Understanding this definition is crucial for EMTs, as recognizing tachycardia can help identify patients who may require immediate medical intervention.

The other options reflect heart rates that do not meet the criteria for tachycardia. A heart rate less than 60 is considered bradycardic, while rates from 60 to 80 would fall within the normal range for adults. A rate exactly at 100 may seem borderline but does not exceed the threshold necessary to classify it as tachycardia unless it is sustained or indicative of other clinical symptoms. Therefore, recognizing that a heart rate over 100 beats per minute is a clear indicator of tachycardia is essential for effective patient assessment and care.
