What the trial is, and whether it could suit you
New-onset supraventricular arrhythmia (NOSVA) is reported in 40 % of patients with septic shock and is associated with hemodynamic alterations and mortality. The lack of consensus regarding best practices for the management of NOSVA in this setting has led to major variations in practice patterns. Observational studies reported three usual strategies: (i) heart rate control (hereafter rate control) with the use of antiarrhythmic drugs, essentially based on low dose of amiodarone, (ii) rhythm control with the use of antiarrhythmic drugs, essentially based on high dose of amiodarone, and electrical cardioversionand (iii) modifiable NOSVA risk factors control (hereafter risk control) without using antiarrhythmic drugs.
Risk control would minimize adverse events of antiarrhythmic drugs. Rhythm control would rapidly improve haemodynamics via restoring diastole and decreasing cardiac metaboli

📋 Eligibility rules (as published)
Inclusion Criteria:
1. Age \>= 18 years
2. Septic shock, defined by the association of the following criteria:
* Documented or suspected infection, with initiation of antibiotic therapy
* Initiation of vasopressors (norepinephrine, epinephrine) for at least 1 hour to maintain the MAP \> 65 mmHg
3. NOSVA with heart rate ≥ 110 bpm lasting 5 minutes or more
4. Written informed consent (patient, next of skin or emergency situation)
5. Affiliation to a social security system
Exclusion Criteria :
1. Refractory shock defined by a dose of noradrenaline BASE or adrenaline BASE \> 1.2 µg/kg/min
2. Cardiac surgery or cardiac transplant in the previous month
3. Aortic or mitral mechanical prosthesis, significant mitral stenosis (mitral surface \< 1.5 cm2)
4. Congenital heart disease other than bicuspid aortic valve, atrial defect or patent foramen ovale.
5. History of supraventricular arrhythmia prior to the episode of septic shock defined by a permanent TRSVN or paroxysmal TRSVN requiring long-term specific treatment (heart rate reducer and/or antiarrhythmic and/or curative anticoagulation) or permanent NOSVA.
6. NOSVA that began more than 48 hours ago \* (or more than 24 hours ago under vasopressor). \* In cases of TRSVN dating back more than 48 hours, the patient may be included after undergoing a transesophageal echocardiogram (only in patients who are intubated and on mechanical ventilation) to rule out the presence of an intracardiac thrombus, coupled with the initiation of curative anticoagulation (in the absence of contraindications contraindication) starting from the transesophageal echocardiography.
7. Electrical cardioversion or use of amiodarone, other antiarrhythmic, or drug inducing bradycardia (beta-blockers, bradycardic calcium channel blocker, digitalis, flécaïnamide) in the previous 6 hours before inclusion
8. Contraindication to amiodarone: history of serious adverse event related to amiodarone, history of lung disease related to amiodarone, history of hyperthyroidism related to amiodarone, PR interval \> 240 ms, severe sinus node dysfunction with no pacemaker, 2°/ 3° atrioventricular block with no pacemaker, QTc\>480 ms, known or treated hyperthyroidism, hypersensitivity to iodine, amiodarone or to any of the excipients, severe hepatocellular insufficiency (prothrombin rate \<20%), diffuse Interstitial Lung Disease.
9. Kalemia \< 3 mmol/L
10. Pregnant or breast feeding women
11. Moribund patient or death expected from underlying disease during the current admission; Patient deprived of liberty and persons subject to institutional psychiatric care
12. Participation to another interventional trial on septic shock and/or arrhythmic disease
