Research output: Contribution to journalConference articlepeer-review


An experimental study was performed to demonstrate that the use of a microbubble ultrasound echogenic contrast imaging agent (MUECIA) is associated with atrial and ventricular premature contractions and polymorphic ventricular arrhythmias when the heart is exposed to pulsed ultrasound. There were no meaningful conduction abnormalities when the heart was exposed to pulsed ultrasound alone or when exposed to MUECIA alone.
