Quizplus · Accepted Answer

Sinus arrhythmia is a type of irregular heart rhythm where the rate changes with the patient's respirations. This typically means that the heart rate will increase during inspiration and decrease during expiration. This is due to changes in the autonomic nervous system, specifically the vagus nerve, which can affect both the respiratory and cardiac systems. Therefore, the correct answer is A) respirations.
