Permanent pacemaker check-up is to ensure normal pacemaker function and to electronically program the pacemaker settings to suit heart’s requirements.

Stress test is to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle). Stress test is used to provide information about how the heart responds to exertion. It usually involves walking on a treadmill at increasing levels of difficulty, while your electrocardiogram, heart rate, and blood pressure are monitored.

VO2 max is the maximum rate of oxygen consumption as measured during incremental exercise on a motorized treadmill. Maximal oxygen consumption reflects the aerobic physical fitness of the individual, and is an important determinant of their endurance capacity during prolonged, sub-maximal exercise. The name is derived from V – volume, O2 – oxygen, max – maximum.
