However, your pacemaker may not prevent escape tachycardias, which is a type of fast heart rhythm, so you may also be prescribed medicines to stop this from happening. [bhf.org.uk]

We also provide support services, including social workers, programs to prevent heart attacks and strokes, and rehabilitation care to help you recover after your treatment. [med.nyu.edu]

This may not prevent tachycardias from occurring so you may also need to take anti-arrhythmic drugs. Some people may need to have an ICD fitted instead of a pacemaker. Medication alone does not help. [c-r-y.org.uk]
