Question number four, a 63-year-old woman is undergoing a treadmill stress test for evaluation of exertional fatigue. The baseline ECG is shown in tracing 4.1a. At peak exercise represented in tracing 4.1b, her ventricular rate is only 68 per minute. Which of the following is the best interpretation of the data? She has chronotropic incompetence due to sinus node dysfunction. She has avenodal disease. She has mixed sinus and avenodal disease. She has hysperkinesis disease, or she has mixed avenodal and hysperkinesis disease. Here is tracing number one in the baseline state. Here is tracing number two, peak exercise, heart rate 68.
