If bradyarrhythmias are severe enough to cause haemodynamic instability, [[atropine]] (0,5 mg) can be given to increase the heart rate. Atropine can be repeated up to 3 mg. As a second choice, [[isoprenaline]] or [[adrenaline]] can be given. Transcutaneous pacing may also be used, where pads applied externally to the chest pace the heart like a pacemaker.<section end="A&IC" /> | If bradyarrhythmias are severe enough to cause haemodynamic instability, [[atropine]] (0,5 mg) can be given to increase the heart rate.
