The patient was taken to the room where the treadmill pulse and blood pressure are recorded at rest. Electrodes attached to the chest and connected to the ECG machine inspection.
This test consists of two parts. The first part of the exercise stress test, you will be asked to walk on a treadmill with specific training procedures, starting from step slow. The Bruce Protocol, the protocol most commonly used, has a total of 7 stages with increased speed and inclination steepness periodically every 3 minutes. Blood pressure, heart rate, and ECG you will be monitored and recorded simultaneously, at rest, and every 3 minutes in each phase of training. The doctor will ask you before a stage is over, are you still able to proceed to the next stage.
There are several considerations that must be followed when the test will be stopped and you do not need to complete the 7 stages. Stages 4-6 are require intense effort, and stage 7 requires maximum effort.
