Absolute indications for stopping an exercise test |
- drop in SBP >10mmHg from baseline despite increasing workload accompanied by other evidence for ischaemia (chest pain, dyspnea) - moderate severe angina (> or = 3 on standard scale) - increasing neuromuscular symptoms (ataxia, dizziness, or near syncope) - signs of poor perfusion - technical difficulties with ECG or SBP monitoring - sustained ventricular tachycardia - ST elevation (+1mm) in leads without diagnostic Q waves - client wishes to discontinue or volitional exhaustion - target has been achieved |
|
|
Relative indications for stopping an exercise test |
- drop in SBP>10mmHg from baseline despite increasing workload (no other evidence of ischaemia) - excessive ST depression (>2mm horizontal or downsloping ST-segment depression) - abnormal arrhythmia - fatigue, dyspnea, wheezing, leg cramps, or claudication - increasing angina - hypertensive response (SBP>250mmHg and/or DBP>115mmHg) |
