A resident with a pulse rate greater than 90 bpm is classified as having which condition?

When a resident has a pulse rate greater than 90 beats per minute (bpm), this condition is identified as tachycardia. Tachycardia is defined as a heart rate that exceeds the normal resting rate, which is typically between 60 to 100 bpm for adults. A heart rate over 90 bpm indicates that the heart is beating faster than usual, which may be a response to various factors such as anxiety, stress, pain, fever, or underlying health conditions.

Understanding tachycardia is essential for healthcare providers, as it can help in assessing a patient's cardiovascular health and determining if further action is needed. It is also important to differentiate it from bradycardia, which is defined as a pulse rate of fewer than 60 bpm, and normal sinus rhythm, which is characterized by a stable heart rate within the normal range. Atrial fibrillation relates to an irregular heart rhythm, which is different from simply having a fast heart rate observed in tachycardia.
