A 68-year-old woman with history of diabetes mellitus, peripheral arterial disease, and breast cancer is referred to your outpatient clinic for decision regarding antithrombotic agents. In laboratory findings, creatinine and platelet count were 0.9 mg/dL and 88,000 × 10⁹/L, respectively.

She was receiving Aspirin 80 mg daily, Rivaroxaban 2.5 mg BD, Pantoprazole 40 mg daily, Atorvastatin 40 mg BD, and Empagliflozin/Linagliptin 10/5 mg daily. Her chemotherapy regimen was Docetaxel + Carboplatin + Trastuzumab.

 Which option is incorrect?

A 50 y/o male patient was admitted in the ICU, due to severe head trauma. He was unconscious (GCS:6) and his past medical history was not clear.
His SBP was 145 mmHg at the time of admission.Emergent craniotomy and hematoma drainage was performed and he was stable in the first day.

Cardiology consult was requested due to rise in Troponin level and ECG changes. 
In day 2, he became hypotensive, that was refractory despite initiating vasopressor agent.
You can find brain CT scan and ECG below.

What’s the best choice ?

Temperature: 36.5°C

Those are the initial ECG that was taken 10 minutes after arrival:
