| We recommend that for patients who arrest in a catheter laboratory the benefits of epinephrine which are mainly based on out-of-hospital arrest randomised controlled trials (RCTs) may also apply in terms of an increased return of spontaneous circulation. | I | A |
| We recommend that for patients who arrest with ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) intravenous epinephrine 1 mg is given after the third shock cycle. | I | A |
| We recommend that for patients who arrest with a non-shockable rhythm intravenous epinephrine 1 mg is given after the third cycle of cardiopulmonary resuscitation (CPR) rather than immediately to allow time for reversible causes of cardiac arrest to be addressed | IIa | C |
