Heart notifications - how to get a tap/haptic/vibration

Hello! I have an Apple watch series 5 and I have the Heart notifications on as I have a severe bradycardia which I need to track. I’m seeing the notifications of my low heart beat when I wake up in the morning as it’s registered in my phone and watch notifications, but I don’t get a tap/haptic/vibration when the low heart event is happening, which I want to activate. Is there something else I need to change so I can feel it which is very important in my case due to the bradycardia? If I have my watch in don’t disturb, will this stop the heart notification? Thanks in advance for your guidance.
