Key result
Long-term automatic event recorders revealed paroxysmal atrial fibrillation in 31% of patients with recurrent palpitations and a negative 24-hour Holter, of which 55% were asymptomatic.

Does a long-term automatic event recorder improve the detection of paroxysmal atrial fibrillation in patients with recurrent palpitations and a negative 24-hour Holter?
Long-term automatic event recorders reveal numerous, prolonged, and often asymptomatic episodes of PAF in patients with palpitations and a negative 24-hour Holter, which would be missed by standard monitoring.
Roche et al. (2002) conducted a cohort in Recurrent palpitations with a negative 24-hour ECG Holter (n=65). Cardiac event recorder with continuous automatic arrhythmia analysis vs. Standard 24-hour monitoring / patient-triggered event recorder (hypothetical) was evaluated on Diagnosis of paroxysmal atrial fibrillation (PAF) episodes. Long-term automatic event recorders revealed paroxysmal atrial fibrillation in 31% of patients with recurrent palpitations and a negative 24-hour Holter, of which 55% were asymptomatic.
