AITAH for telling my husband that I wasn’t sure that he “wouldn’t let me die”?

Last night I (48F) had a really scary health event. For context, it started with a really intense calf cramp, which slowly moved up into my abdomen and then my chest. I was having pain and tightness in my chest, and I felt like I was gasping for air. My blood pressure dropped to 50/31 and I truly believed for the first time that I might die. I was starting to black out and couldn’t hear my own voice or anything around me. I told my husband (46M) that I needed to go to urgent care or the hospital, which I’ve only ever said once before in my life, so it’s not like I would normally jump to asking for emergency help unless I REALLY thought I needed it. About 20 minutes into this episode, my husband finally said he was going to change his pants and put on shoes so he could drive me to urgent care. He told me to lie down, so I did, and when I tried to get up to go, i got really sick to my stomach and thought I was going to throw up or pass out, so I laid down again. I kept telling my husband to wait, it seemed like my symptoms were starting to get better, and ultimately I didn’t go to the hospital.

Cut to this morning, after we got up, I said to him that I was really feeling concerned about what happened and that I was going to follow up with my doctor to make sure that there was no underlying issues to address. He kind of blew it off and suggested that it was just a onetime thing that probably won’t ever happen again. For me, it was so scary, and I truly thought I might die, so it hurt to hear him minimize the experience. He told me he’d never let me die, and I responded that I wasn’t sure that he wouldn’t let me die since he waited so long to decide to take me to urgent care or call 911. I didn’t mean it like I thought that he’d purposely let me die, just that you can’t really know when something like that is an actual emergency or not which is why most people just call 911 or go to a hospital instead of waiting. Now he’s so angry with me for insinuating that he would let me die in an emergency. I tried explaining what I meant, but he is too angry to hear it or try to understand.

So, AITAH for being insensitive? Or is HE the one being insensitive? I just don’t understand why he is so angry at me over this.
