where is the pacemaker in the heart

The pacemaker generator is typically placed under the skin of the chest, usually just below the collarbone on the left side, though it can be implanted on the right side or, in some cases, other locations depending on anatomy and surgical preference. Leads run from the generator into the heart to coordinate heartbeats. This setup places the device outside the heart but connected to it to regulate rhythm. If you’d like, I can summarize common locations, why a side is chosen, and what to expect during recovery. [web results indicate chest/ collarbone placement as standard]
