Such individuals upon taking Bactrim could present with irregular heartbeats and life-threatening ventricular arrhythmias. Individuals with history of chronic disturbance in serum magnesium and potassium ions are at increased risk for arrhythmias. Also, individuals taking Lasix are at increased risk for losing potassium, thus setting the ground for life-threatening arrhythmias, upon taking Bactrim.
