Your doctor will order to have your pacer checked regularly to make sure that it is working correctly and that the settings are right for you. The process of checking your pacemaker’s settings is called an interrogation. The strength and length of the impulse is sent to the heart muscle and how fast the pacemaker will go can be programmed.
