What does 'tachycardia' indicate in a patient?

Tachycardia is a medical term that specifically indicates an increase in heart rate. In adults, a resting heart rate over 100 beats per minute is generally considered tachycardic. It may arise from various factors, including stress, anxiety, fever, medications, or underlying health conditions such as heart disease.

Understanding heart rate is crucial in a clinical setting, as tachycardia can be a sign that the body is responding to stress or may indicate a potential health crisis requiring further evaluation. It is essential for healthcare providers to monitor heart rate carefully, as both elevated and reduced rates can have significant implications for patient care. Recognizing tachycardia helps in determining appropriate interventions and treatment plans.
