Joe had experienced a recent respiratory infection but felt he was responding well to over-the-counter medications. He still had a low-grade fever, however. He was awakened during the night with pain in the thoracic region. Fearful that the symptoms might indicate a heart attack, he called 911 and was transported to the emergency department. On the way to the hospital, the paramedic advised Joe that his EKG was normal. After all tests for cardiac illness and pathology returned negative, Joe was sent home on antibiotics, pain medication, and with recommended bed rest. From your study of tissues and membranes, what might be the reason for this treatment? Explain your answer in 4 to 5 sentences. Indicate the reference/s of your answer.
John is your 68-year old neighbor who was recently told by his doctor that his heart’s main pacemaker stopped working (“They told me it is called an SA node”). He knows you are a nurse, so he came to you to ask why his heart is still beating, but only at a rate of 50 times per minute. Please explain using appropriate physiological and anatomical details.
