질식하다 (to choke, to suffocate) is 질식해요 in the polite 해요체, 질식합니다 in formal 합니다체, 질식해 in casual 반말 and 질식한다 in the plain written style. The past is 질식했어요.

What is the past tense of 질식하다?

질식했어요 in everyday polite speech, 질식했습니다 formally. It is built from the 아/어 form 질식하여 plus ㅆ, which is why an irregular stem shows its irregularity here.

Is 질식하다 irregular?

Yes — it is 여 irregular (여 불규칙). 하다 and every verb built on it: 하다 → 하여 → 해요. That is why the stem looks different in 질식하여 and 질식하니 but unchanged in 질식합니다.
