Wellbutrin can cause temporary heart irregularities. On average, it takes the body about 4-6 weeks to get fully used to most antidepressants. I was diagnosed with sinus tachycardia, but it has mostly gone away. It comes back at times with anxiety and panic attacks. If it's not causing pain, I wouldn't worry too much about it. If you are really worried, ask your doctor for a referral to a cardiologist to get a full workup done.
