[Ultrasound in treating cardiac dysrhythmia]

Ultrasound was used in the treatment of cardiac arrhythmia. Suppression of automatic activity of pacemaker cells, a trend to reduction of AV junction transmittancy and prolongation of its refractory period in response to specially programmed ultrasound may contribute to elimination of tachyarrhythmia paroxysms in some patients. Ultrasound therapy should be used with caution in suspicion of sinus insufficiency and AV junction failure. Ultrasound in the treatment of cardiac arrhythmia seems perspective and requires further studies.
