Q. A 61-year-old man comes to the emergency department because of a transient loss of consciousness (syncope). During the last few days, he reports heart palpitations that he attributed to exertion. The patient's past medical history is significant for diabetes, hypertension, and Parkinson's disease. He recently underwent coronary revascularization after an inferior myocardial infarction. His blood pressure is 80/50 mm Hg, heart rate 40/min, respiratory rate 12/min, and his temperature is 37 degrees Celsius. Cardiac and chest auscultation is within normal limits, and no jugular venous distention is noted. Based on his history, physical exam findings, and ECG (see image), which of the following best describes this patient's expected central venous pressure waves?
