Summary of Key Issues and Major Changes made in 2015
The combined use of vasopressin and epinephrine offers no advantage to using standard-dose epinephrine in cardiac arrest and therefore vasopressin has been removed from the ASCL cardiac arrest algorithm.
In cardiac arrest patients with non-shockable rhythm and who are otherwise receiving epinephrine, the early provision of epinephrine is suggested.
There is a strong association between early administration of epinephrine and increased ROSC, survival to hospital discharge, and neurologically intact survival.
One observational study suggests that ß-blocker use after cardiac arrest may be associated with better outcomes than when ß-blockers are not used, however,  the routine use of
ß-blockers after cardiac arrest is potentially hazardous because ß-blockers can cause or worsen hemodynamic instability, exacerbate heart failure, and cause bradyarrhythmias.

8. When interrupting cardiac rhythms remember:
Rate: achieved by counting QRS spikes
Rhythm: use calipers to determine QRS spikes are equal
P Wave: assess for presence prior to QRS complex
PR Interval: measure from beginning of P wave to the beginning of QRS complex
QRS: Assess base of QRS for width; is it wide or narrow?

9. For Example:
Rate: 80 beats per minute
Rhythm: Regular
P Wave: Present before every QRS complex
PR Interval: 0.20
QRS: 0.08
Interpretation: Normal Sinus Rhythm
