A patient with tachycardia has a?

Tachycardia is a medical condition where the heart rate is abnormally high, typically over 100 beats per minute. Therefore, a patient with tachycardia would have a rapid pulse. Slow pulse (option A) would refer to bradycardia, where the heart rate is abnormally low. Irregular pulse (option B) could indicate arrhythmia, a condition where the heart beats irregularly. Normal pulse (option D) would refer to a heart rate within the normal range of 60-100 beats per minute, which would not be considered tachycardia.
