I had a Medtronic 2 lead Pacemaker installed on 07/16/2020. The first few nights of sleep eluded me. I was to afraid to sleep. I am now able to get 5-6 hours of sleep. I've been getting lightheaded quite often. Is this normal. I also have Asthma. I've noticed after using my Nebulizer with Albuterol I seem to be getting a fluttering feeling in my chest. Is the Pacemaker trying to compensate for the temporary increase in the heart rate caused by the Med. Any help will be greatly appreciated.
