Which of the following conditions is where the heart muscle cannot contract even though electrical activity appears on the ECG?

What heart condition do the waves in the ECG tracing below represent?

An ECG tracing from a patient with a pacemaker may have wide or bizarre __________ if the pacemaker captures the chamber it is pacing.
