Sinus Arrhythmia (SA) Normal except irregular


The difference between the fastest two heart beats (from 1 QRS to the next QRS) and the

slowest two heart beats is greater than .12 sec




Asystole No electrical activity


CODE BLUE

but it does arise from the SA node??




Pulseless Electrical Activity (PEA) Normal rhythm, but...No Pulse*


Electrical activity is present but there is no pulse, so the heart is not beating! Something has

happened to prevent the muscular tissue from responding to the electrical activity

(i.e. ↓↑ K+, hypothermia, Pneumothorax, cardiac tampanode, hypovolemia, drug overdose,

pulmonary or coronary thrombosis)

Sinus Tachycardia

Sinus Bradycardia
