What does the term "tachycardia" refer to?

The term "tachycardia" specifically refers to an abnormally fast heart rate, typically defined as a heart rate exceeding 100 beats per minute in adults. This physiological condition can arise from various factors, including stress, anxiety, fever, or underlying health issues such as heart disease. Understanding tachycardia is crucial for paramedics and medical professionals because it can indicate underlying health problems that may require immediate attention. Recognizing the signs of tachycardia helps in the effective assessment and management of patients who may be experiencing cardiovascular distress.
