You're definitely doing the right thing by planning to ask his cardiologist. With something as important as a new pacemaker, it's always better to get advice that's specific to his situation rather than relying on mixed information online.

From a practical standpoint, if he does end up using a lift chair or any other mobility aid, it can really help to ask about day-to-day use, positioning, and any precautions that the manufacturer or healthcare team recommends. That way, everyone feels more confident and comfortable using it.

Hopefully, you'll get some reassurance from his medical team soon. Wishing your father a smooth recovery and continued improvement.
