Table 4 Absolute and relative criteria indicating termination of ergometry [31]
Absolute indication | Relative indication |
|---|---|
ECG ST-segment depression ≥3 mm | Hypertensive dysregulation (RRsyst 230–260 mmHg, RRdiast ≥ 115 mmHg) |
ECG ST-segment elevation ≥1 mm | Drop in blood pressure > 10 mmHg (compared to baseline blood pressure) without signs of myocardial ischemia (no angina pectoris, no ECG ST-segment depression) |
Drop in blood pressure > 10 mmHg (compared to baseline blood pressure) with signs of myocardial ischemia (angina pectoris, ECG ST-segment depression) | Polymorphic extrasystols, duplets (2 consecutive ventricular extrasystols), salves (≥ 3 consecutive ventricular extrasystols) |
Moderate-severe angina pectoris-symptoms | Supraventricular tachycardias |
Severe dyspnea | Bradyarrhythmias |
Clinical signs of less perfusion (cyanosis) | Line faults |
Persistent (duration >30 s) ventricular tachycardias | Presence of line faults (high AV-blockage, branch block) |
Exhaustion of the patient | reinforced angina pectoris symptoms |
Technical problems (defect ECG-registration, monitor failure) |
