Can i die from while having a pacemaker?

No: Pacemaker implantation is a routine procedure for experienced operators. While there are risks to any procedure, the risk of serious adverse events with pacemakers is quite low. Most people commonly are a little sore and may have some swelling in the area for a few days.

Yes.: Yes, but the risk is very low, <1%.

Assuming...: I'm assuming you mean "what can i die of while getting a pacemaker?" ok - puncture of the heart by the pacemaker wire is by far the most common way, and occurs 1:1500-1:2000 cases. Puncture of the lung and bleeding can both occur but are usually treatable and rarely fatal. Infection of the pacemaker system itself is serious and usually treatable, but can result in death in severe cases.
