Complicated Heart Condition

My dad has a complicated condition. He is a diabetic, his EF has fallen to 15%.

Further, due to the weak pumping of his heart, his kidneys are not fuctioning properly. The kidneys had stopped functioning about 25 days back, then they started functioning with medication given at the hospital, and then they stopped functioning again.

Finally the doctors decided to start dialysis as water started accumalating and this was causing further strain on his heart.

Currently, dad is on dialysis 3 times a week.

Dad has been in hospital for the past 25 days, and his dialysis has started about 10 days back.

Whilst in hospital, he had put on approximately, 10 kgs due to water retention. This is now improving with since we started the dialysis.

The doctors are suggesting that we put a bi-ventricular pacemaker, however, my dad is not in any condition to do the operation. The doctors recommended that we continue with the dialysis for a while and then do the pacemaker operation.

Could someone please help me with the following questions:
How long do we have to wait to put the pacemaker on?
Is there any possibility that once the pacemaker is put, how much can the EF improve?
Is there ANY possibility that his kidneys will start functioning again?

For some insight, the heart problem may be secondary to the kidney disorder.  If there is an overload of fluids (volume) that condition will/can overwork the heart and as a result the heart becomes weak and almost always the heart size will increase. The 15% of blood pumped into circulation with each heart stroke can back up the blood received from the lungs and fluids can leak into lung tissues and cause congestion...

There has to be a reduction of fluids (blood volume) before there can be good heart pumping functionality, and that may cause a delay for the implant..  Sometime with a heart disorder, the heart doesn't beat regularly and often a pacemaker can correct the problem. A pacemaker is a small device that sends electrical impulses to the heart muscle to maintain a suitable heart rate and rhythm. A pacemaker may also be used to treat fainting spells (syncope), congestive heart failure, and hypertrophic cardiomyopathy.  A pacemaker implant is more for assurance of good, normal heartbeat than a remedy for heart failure.
