Recommendations and Levels of Evidence for Acute Treatment of AT
| COR | LOE | GOR (MINDS) | LOE (MINDS) | |
|---|---|---|---|---|
| Emergency synchronized electrical cardioversion for the termination of hemodynamically unstable or drug‐resistant AT 645 , 646 | I | C | C1 | VI |
| Intravenous β‐blockers, diltiazem or verapamil for the termination of hemodynamically stable AT or rate control therapy 640 , 647 , 648 , 651 | IIa | C | B | IVb |
| Intravenous adenosine triphosphate for the termination of AT or differential diagnosis of SVT 640 , 650 , 651 | IIa | B | B | III |
| Intravenous Class I antiarrhythmic drugs for the termination of hemodynamically stable AT without organic heart disease 640 , 649 , 652 | IIa | C | B | IVb |
| Self‐administration of Class I antiarrhythmic drugs (pill‐in‐the‐pocket) for the necessary confirmation for efficacy and safety of drugs on ECG before this approach * 104 | IIa | B | B | II |
| Intravenous Class I antiarrhythmic drugs for the termination of hemodynamically unstable AT or AT with moderate/severe cardiac dysfunction 1 , 21 | III | C | C2 | IVb |
| Intravenous Class I antiarrhythmic drugs for the termination of AT in patients with Brugada syndrome or tachycardia–bradycardia syndrome 1 , 21 | III | C | C2 | IVb |
*
For example, severe bradycardia following termination of AT, occurrence of bundle block, cardiac dysfunction according to negative inotropic action, past history of atrial flutter.
