WebD) Inferior. Answer: C. Explanation: Atrial dysrhythmias are caused by an ectopic impulse in either the right or the left atrium. 3) In a premature atrial complex (PAC), the P wave may be biphasic. This means that: A) the waveform has both positive and negative deflections on the ECG tracing. B) the P wave is hidden within the T wave.
