regex - Multiple Line Search in Notepad++ -

I am looking for a way to identify missing records within a record group in Notepad ++. Each record group starts with Tild and ends. However, some group expansion records (H1 records) are lost. In the example below, I need to find bold / italicized entries.

~ H1 ~, 10222,30333, Jones
Midwest Emergency, 123456


H1 ~, 30334, 3234543, Smith
Midwest Emergency, 933233


Midwest Emergency, 92345434


H1 ~, 3232353434,232343534, Horst
Midwest Emergency, 223342545


Modern Emergency, 2334333



H1 ~, 3055543,33232322, Vice
South Emergency , 233446655
