The incidence of cardiac arrhythmias during exercise stress testing: a focus on patients with severe obesity undergoing sleeve gastrectomy
Authors' conclusion
Although in the early post-surgical phase the risk of exercise-induced arrhythmias may be higher, SG does not seem to increase the occurrence of arrhythmias in the long-term. No life-threating arrhythmias were found during post-SG evaluations.
Study context
- Population
- Patients with moderate or severe obesity, candidates for sleeve gastrectomy (SG), June 2015–September 2020severe obesity
- Participants
- 50 patients
- Exposure
- Before vs 6 and 12 months after SG
- Outcome
- Frequency and complexity of ventricular premature beats (VPBs) and atrial premature beats (APBs) during rest, exercise and recovery phases of maximal exercise testing
- Follow-up
- 1 month before and 6 and 12 months after SG
Methodological detailsbefore-and-after, ECG-monitored maximal cardiopulmonary exercise testing
- Before-and-after
- ECG-monitored maximal cardiopulmonary exercise testing
Main finding
As reported in the abstract
VPBs during exercise testing · 6 and 12 months post-SG
- At 6 months post-SG, an increase in ventricular premature beats (VPBs), mainly during the recovery phase
- At 12 months post-SG, a reduction in VPBs compared with the 6-month evaluation
Observational data: associations, not effects.
