Compared to amiloride treatment , the chlorthalidone phase was associated with an increased frequency of ventricular ectopic beats ( 24 - hour Holter monitoring ) and a higher Lown grading , increased upslope and duration of the monophasic action potential , prolonged ventricular effective refractory period , and increased electrical instability during programmed ventricular stimulation .
