What heart rate is generally considered tachycardia?

Tachycardia is defined as a heart rate that exceeds the normal resting range, which is typically considered to be between 60 to 100 beats per minute for adults. When the heart rate rises above 100 beats per minute, it is categorized as tachycardia. This elevated rate can occur for various reasons, including physical activity, emotional stress, fever, or underlying medical conditions. Understanding this threshold is vital in clinical practice for diagnosing and managing patients with potential heart rhythm disturbances. The other ranges mentioned do not meet the criteria for tachycardia, as they either fall within the normal range or below it. Therefore, recognizing that a heart rate above 100 beats per minute indicates tachycardia is essential for proper assessment and intervention.
