It would be impossible to say for sure.
I get Bigeminy, which is one premature beat and one normal beat. You don't feel the premature beat. Many Premature Ventricular Contractions have a Compensatory Pause after them, allowing the heart to fill with a little more blood than usual, during the pause, and is followed by a normal beat that feels like a thump as the extra blood is ejected. Some forms of Premature Ventricular Contractions, known as Interpolated PVCs, don't have a pause.
