A week ago at my first checkup, Medtronic changed my upper pm limit to 140 and turned the rate response setting to on. When I brushed my teeth and washed my face this morning I was totally breathless ! Called Dr. who said that Medtronic was coming today so I went in. The "delay" setting has been changed from factory setting of 200ms to 150ms - their feeling is that atria is signaling before ventricles have a chance to empty so that blood may be backing up causing my feeling of having my heart in my throat. Make sense to you?
Also apologize - tried to use the chat room and messed up. What is the upper limit for characters in a chat room message?
