What is defined as a heart rate greater than 100 beats per minute?

The term that describes a heart rate greater than 100 beats per minute is tachycardia. This condition indicates that the heart is beating faster than the normal resting rate, which typically ranges from 60 to 100 beats per minute for adults. Tachycardia can arise from various factors such as stress, anxiety, fever, or underlying medical conditions, and it signals that the heart is working harder to meet the body's demands for blood and oxygen. Understanding this term is crucial in a clinical context, as it helps healthcare providers identify potential cardiovascular issues that may need further evaluation or intervention.
