Table 4 Absolute and relative criteria indicating termination of ergometry [31]

From: Internet-based perioperative exercise program in patients with Barrett’s carcinoma scheduled for esophagectomy [iPEP - study] a prospective randomized-controlled trial

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)
