External and internal forces can cause dysrhythmia. External factors include exhaustion, overexertion, emotional stress (such as Annie's campaign speech), cigarette smoking, drinking alcohol, and ingesting stimulants such as caffeine, decongestants, and cocaine.

This can happen if the special nerve cells that produce electrical signals don't work properly. An arrhythmia also can occur if another part of the heart starts to produce electrical signals.
