Does the Valsalva maneuver induce atrial fibrillation in patients with PSVT after cardiac surgery?
The Valsalva maneuver, a guideline-recommended first-line treatment for PSVT, may carry a risk of inducing atrial fibrillation in patients who have recently undergone cardiac surgery.
Answers are grounded in this paper and cite their sources.
Valsalva may induce AF in post-cardiac surgery PSVT; hypothesis-generating case that should not change practice.
According to the recent guidelines, both vagal maneuvers and intravenous adenosine are recommended as the first-line treatment for paroxysmal supraventricular tachycardia (PSVT). We report a case of atrial fibrillation (AF) induced by the Valsalva maneuver performed to terminate PSVT in a male patient after cardiac surgery. Although the efficacy of Valsalva maneuver and modified Valsalva maneuver for PSVT treatment is well known, this case suggests that these maneuvers can have a risk of inducing AF, especially after cardiac surgery. Adenosine can be an alternative strategy when the heart rate is easily controllable by epicardial pacing wires.
