Implication
P wave dispersion may aid PAF identification on ECG; leaves open prospective validation before clinical use.
Structured PICO
Does P wave dispersion on 12-lead ECG identify patients with paroxysmal atrial fibrillation?
P
Population
160 subjects, comprising 90 consecutive patients with a history of idiopathic paroxysmal atrial fibrillation (46 men, 44 women; aged 55 +/- 13 years) and 70 healthy subjects (42 men, 28 women; mean age 53 +/- 14 years).
I
Intervention
Measurement of P wave dispersion (PWD) and P maximum duration on 12-lead surface ECG
C
Comparator
Healthy control subjects
O
Outcome
Identification of patients with idiopathic paroxysmal atrial fibrillationsurrogate
P wave dispersion and maximum P wave duration on standard 12-lead ECG are significantly higher in patients with idiopathic paroxysmal atrial fibrillation and can serve as simple markers to identify these patients.
