Dihydroartemisinin-piperaquin (DHA-PPQ) has been used globally as standard combination therapies for vivax malaria treatment. One of the side effects that must be put into caution is the prolongation ofventricular repolarization, which can lead to the development of ventricular arrhythmia known as Torsadede Pointes (TdP). This study used ‘before and after’ design and was aimed to find out whether there was asignificant difference of QTc and JTc interval of vivax malaria patients pre and post DHA-PPQ and Primaquin(PQ) dose. The ECG record of DHA-PPQ and PQ, respectively, 24 and 14 subjects. QT and JT intervalsare affected by heart rate, thus, both of them have to be corrected according to the heart rate using twoformulas, i.e.: Bazett (QTcB, JTcB) and Fridericia (QTcF, JTcF) formulas. The results showed significant QTcFprolongations of 14.42 ms predose and 20.53 ms postdose on D3 DHA-PPQ treatment compared to thebaseline value, whereas prolongations of JT interval were 13.43 ms found on D3 postdose. The results aftergiven PQ showed mean difference of QTcB compared to the baseline value was 19.42 ms. The result for JTcFinterval after given PQ, showed mean difference of prolongations compared to the baseline value was 16.50ms, which was statistically significant.
