Hi there, I had a CRT-D inserted 2 weeks ago. Post Op has been smooth until yesterday when I started feeling dizzy and had slight chest pain, with some crazy palpitations. Has just happened again in the last hour. Can anyone give me an idea if this is normal. My BP is low, usually around 90/70 but during these spells rises to around 130/85. Would really love some input, feeling very alone and anxious.
