Her father, born in 1965, suffered from high blood pressure and heart disease, and had just had a pacemaker installed at the hospital on September 17, 2021. Now, my father is in the hospital for observation, but today, the incision is swollen. So the doctor asked me if the incision with the pacemaker was swollen? Is it good to install it? What to avoid and what to avoid and related to such a pacemaker? Thank you doctor.

My grandmother had heart failure of grade 3, mitral valve regurgitation, and broke a wire in the aorta, so she was often tired. The treating doctor advised her to put on a pacemaker. She is 86 years old this year. So the doctor asked me if the elderly with heart failure and heart valve regurgitation should have a pacemaker?
