A non-conducted PAC (premature atrial contraction) does not affect the ventricular response rate because it is essentially a beat that occurs early in the heart cycle and is not followed by a corresponding ventricular contraction. When a PAC happens, it can interrupt the normal rhythm, but if it does not conduct through to the ventricles, there will be no resulting ventricular contraction from that PAC.

In a normal conduction pathway, the atrial impulse should reach the ventricles; however, in the case of a non-conducted PAC, the impulse fails to trigger a response in the ventricles in the same cycle. Therefore, since there is no ventricular contraction associated with the non-conducted PAC, the overall heart rate and ventricular response remain unchanged.

This understanding is key in telemetry and arrhythmia management, as it helps in determining the impact of different types of arrhythmias on cardiac output and patient stability.
