The following mnemonic directs AHA accepted actions after absolute (<60bpm) or relative (slower rate than expected) bradycardia with circulatory compromise due to the slow rate is discovered. Start the Secondary ABCDs and remember:
*Pacing Always Ends Danger

| Mnemonic |
Intervention |
Note |
| Pacing |
**TCP |
Immediately prepare for transcutaneous pacing (TCP) with serious circulatory compromise due to bradycardia (especially high-degree blocks) or if atopine failed to increase rate. |
Consider medications while pacing is readied. |
| Always |
Atropine |
1st-line drug, 0.5 mg IV/IO q3-5 min. (max. 3mg) |
| Ends |
Epinephrine
2-10 µg/min |
2nd-line drugs to consider if atropine and/or TCP are ineffective. Use with extreme caution. |
| Danger |
Dopamine
2-10 µg/kg/min |
|
*Pacing does not "always end danger" in bradyarrhythmias. If the above measures do not improve circulatory stability the bradycardia may merely be an indication of a pathological process, think Differential Diagnosis!
**Prepare for transvenous pacing (TVP), managed by an expert, if TCP fails.
