Single time point lead-I ECG devices for the detection of AF in people with signs or symptoms of AF and an irregular pulse appear to be a cost-effective use of NHS re sources compared with MPP followed by a 12-lead ECG in primary or secondary care , given the assumptions used in the base-case model .
BACKGROUND Atrial fibrillation ( AF ) is the most common type of cardiac arrhythmia and is associated with an increased risk of stroke and congestive heart failure .
Lead-I electrocardiogram ( ECG ) devices are h and held instruments that can be used to detect AF at a single time point in people who present with relevant signs or symptoms .
OBJECTIVE To assess the diagnostic test accuracy , clinical impact and cost-effectiveness of using single time point lead-I ECG devices for the detection of AF in people presenting to primary care with relevant signs or symptoms , and who have an irregular pulse compared with using manual pulse palpation ( MPP ) followed by a 12-lead ECG in primary or secondary care .
Long-term risk of recurrent atrial fibrillation as documented by an implantable monitoring device: implications for optimal patient care.
OBJECTIVES The present study determined the incidence and time course of atrial fibrillation ( AF ) recurrences  in patients with a history of AF and fitted with an implantable monitoring device .  BACKGROUND The long-term risk of undetected recurrence of AF in patients receiving stable antiarrhythmic therapy remains uncertain . METHODS In 110 patients with a class I indication for physiologic pacing and a history of AF , a pacemaker with dedicated functions for AF detection and electrogram storage was implanted , and antiarrhythmic drug treatment was optimized . Patients were regularly followed up with evaluation of AF-related symptoms , a  resting electrocardiogram ( ECG ) , and  interrogation of device memory .  The incidence of AF recurrences lasting > 48 h in asymptomatic patients presenting in sinus rhythm ( SR ) at the respective follow-up visit constituted the primary end point of this prospect i ve study . RESULTS During 19 + /- 11 months , 678 follow-up visits were performed . Atrial fibrillation was documented in 51 patients ( 46 % ) by ECG recording and in 97 patients ( 88 % ) by a review of stored electrograms ( p < 0.0001 ) . Device interrogation revealed AF recurrences lasting > 48 h in 50 patients , 19 of whom ( 38 % ) were completely asymptomatic and in SR at subsequent follow-up . In 11 ( 16 % ) of 67 patients with device-confirmed freedom from AF for > or =3 months , AF lasting > 48 h recurred subsequently . CONCLUSIONS This prospect i ve study demonstrates a high incidence of recurrent AF despite optimized antiarrhythmic therapy . Of particular note , AF relapses > 48 h remained totally asymptomatic in a significant proportion of patients . Freedom from AF for > or =3 months did not preclude subsequent long-lasting AF recurrence
