Figure 1 Diagram showing systolic blood pressure (BP) and heart rate responses during exercise and the recovery phase in a severely symptomatic 16-year old girl with nonobstructive hypertrophic cardiomyopathy (patient #1 in Table 2). Systolic blood pressure failed to increase from the baseline value of 100 mm Hg, and the test was interrupted after 2 min and 30 s due to hypotension (baseline systolic blood pressure of 100 mm Hg dropping abruptly to 80 mm Hg) associated with dizziness. This patient died suddenly and unexpectedly six months after the exercise test.
