The QRS complaex on an ECG is representative of the patient's ventricles contracting. The left ventricle is responsible for perfusing the blood to the rest of the body (the most important part).
I'm assuming that you are refering to an ICD (implanted cardiac defibrillator). These devices are "tweaked" to recognize the patient's QRS complex. When the patient doesn't make their own, or rather makes an irregular one, the ICD "fires", thus defibrillating the patient's heart into a normal rhythm.

If the patient had a pacematker, I would think it meant the patients own heart beat, vs not the pacemaker. Also, some times hospitals apply external pacemakers on the heart, so maybe a diferance between the pacemaker and own heart beat. Cause the pacemakers make their own complexes.
