Absence of angina or other significant symptoms (e.g., unusual shortness
of breath, light-headedness, or dizziness heart rate and systolic blood
pressure with increasing workloads and recovery) |

Moderate Risk |
• |

baseline) during exercise testing or recovery |

chronotropic incompetence or flat or decreasing systolic BP with
increasing workloads) or recovery (i.e., severe postexercise
hypotension) |
