From: General anesthesia in a patient with asymptomatic second-degree two-to-one atrioventricular block
Intraoperative monitor electrocardiogram following induction of general anesthesia. The traces show complete atrioventricular block with junctional escape rhythm of approximately 30–40 beats per minute. The P waves (marked) were completely dissociated from the QRS complexes. Artifacts most likely due to poor electrode contact with the skin caused the noisy baseline in this tracing
