49 year old woman with large basal infarction and documented Möbitz 2 AV block requiring pacing. Following multiple arrests the pacemaker threshold rose from 1.0 to 6.0 mAmps and the tracing shown below was obtained. What are the conduction abnormalities observed? What is the likely position of the pacemaker tip?
