Arm | Intervention/treatment |
---|---|
Experimental: Amiodarone
Amiodarone - administered intravenously Bolus of 150 mg is given over a minimum of 10 min, with subsequent continuous infusion of 1 mg/min for 6 h, next continuous infusion of 0.5 mg/min for 18 h, then switch to oral administration. Oral administration 200 to 400 mg/day (adjust dosage based on cardiac response and age) up to discharge. |
Drug: Amiodarone
Ion channel blocker |
Experimental: Verapamil
Verapamil - administered intravenously Bolus of 0.075-0.15 mg/kg (5-10 mg) over at least 3 minutes, then switch to oral administration. Oral administration 120 to 480 mg/day in divided doses every 6-8 hours (adjust dosage based on cardiac response and age) up to discharge. |
Drug: Verapamil
Ion channel blocker |
No Intervention: Usual Care |
- Clinical improvement [ Time Frame: Randomization to day 15 ]Time to first occurrence of clinical improvement assessed on a seven category scale ranging from 1 to 7
- Clinical improvement [ Time Frame: Randomization to day 7 and 28 ]Time to first occurrence of clinical improvement assessed on a seven category scale ranging from 1 to 7
- Cardiac troponins [ Time Frame: 7, 10 and 15 days after randomization ]assessed serially
- Mortality [ Time Frame: Randomization to day 28 ]Individual endpoint
- Time to resolution of fever [ Time Frame: Randomization to day 28 ]Defined as body temperature (≤36.6°C [axilla], or ≤37.2 °C [oral], or ≤37.8°C [rectal]) for at least 48 hours without antipyretics or until discharge, whichever is sooner.
- Tachyarrhythmias [ Time Frame: Randomization to day 28 ]defined as atrial fibrillation, supraventricular or ventricular tachycardia requiring treatment
- Time to clinical improvement from admission using the 7-point ordinal scale [ Time Frame: Randomization to day 28 ]Clinical improvement assessed on a seven category scale ranging from 1 to 7.
- Change in NEWS2 score [ Time Frame: Randomization to day 7 and 15 ]The National Early Warning Score (NEWS2) score. A Higher score is worse.
- Duration of hospitalization [ Time Frame: Randomization to day 28 ]Length of hospitalization in days
- PO2/FIO2 [ Time Frame: Randomization to day 7 and 15 ]oxygenation index defined as quotient of partial pressure of oxygen in arterial blood (PaO2, in mmHg) and fraction of inspired oxygen (FiO2)
