What is tachycardia?

Tachycardia refers to an elevated heart rate, typically defined as a resting heart rate exceeding 100 beats per minute in adults. This condition can occur in response to various factors such as physical activity, emotional stress, or certain medical conditions. Understanding tachycardia is important for assessing a patient's cardiovascular health, as it may indicate underlying issues that require attention, such as dehydration, fever, anemia, or heart disorders. The identification of tachycardia allows healthcare providers to investigate the cause and determine the appropriate interventions necessary to address the patient's health status.
