Why the study?
What are the immediate electrocardiographic changes following synchronized d.c. cardioversion in patients with atrial fibrillation or flutter?
What are the immediate electrocardiographic changes following synchronized d.c. cardioversion in patients with atrial fibrillation or flutter?
Immediately following synchronized d.c. cardioversion for atrial fibrillation or flutter, there is typically no compensatory pause and the first QRS complex is frequently aberrant.

May aid post-cardioversion ECG interpretation in AF; case report leaves open confirmation in larger cohorts.
Electrocardiograms were registered with a special technique during attempts at cardioversion in 22 patients with atrial fibrillation or flutter. The registrations permitted analysis of the electrocardiogram 0.1-0.5 s after the electrical discharge. Mean values indicate that there is no compensatory pause after the d.c. shock. After 29 of the 42 synchronized d.c. shocks the first QRS complex was aberrant.
