Does atrial stimulation within the vulnerable period produce atrial fibrillation in normal subjects?
Stimulation within the atrial vulnerable period can induce transient atrial fibrillation in normal subjects.
Twenty-six episodes of atrial fibrillation and flutter-fibrillation, each lasting less than 23 sec, were recorded in three normal subjects during atrial pacing studies. The cause of these atrial arrhythmias was determined to be the result of stimulation within the atrial vulnerable period.
