Bradyarrhythmia screening ‘does not improve clinical outcomes’

There was no difference in clinical outcomes between patients screened using an implantable loop recorder and those who received usual care.

Long-term continuous ECG monitoring to detect and treat bradyarrhythmia in older adults does not lower the risk of sudden cardiovascular death or syncope compared to usual care, a study shows.

Although there was a sixfold increase in diagnoses and a higher pacemaker implantation rate, Danish researchers reported no clinical benefit from screening for the arrhythmia using an implantable loop recorder (ILR).
