Normal Sinus Rhythm
PR Interval: 0.12-0.20
QRS: Less than 0.12
QT: 0.36-0.44
Sinus Tachycardia: 101-150 bpm
Sinus Bradycardia: < 60
Sinus Arrhythmia: Irregular, can change when pt breathe in or
out (in fast, out slow)
PACs: Premature Atrial Contraction
-Has a P Wave but is slightly different Types of PVCs:
-Has a pause after, then returns to NSR Multi-formed (from diff areas of the heart)
Couplets (2 PVCs in a row)
PVCs: Premature Ventricular Contraction Bigeminal (every other beat)
-No P Wave, Wide QRS complex (greater than 0.12) Burst of V Tach (8 PVCs in a row)
R on T (PVC early in cycle -apex of t wave)
BBB: Everything is normal, but the QRS is widened (greater than 0.12) (BUNNY EARS)
-No treatment. Comes & goes on it’s own
A Fib: Irregular & no discernable P Wave
-Atrium doesn’t know who wants to be in charge to start P Wave.
-↑ risk of stroke ***
-If you have A Fib over 100 bpm = RVR (Rapid Ventricular Rate)
-Tx: amiodarone, anticoagulants (warfarin), if meds don’t work → synchronized cardioversion
(if no blood clots) ASPIRIN IS NOT AN ANTICOAGULANT IT IS AN ANTIPLATELET
A Flutter: Sawtooth, F waves
-Tx: same as A Fib, can give beta blockers, calcium channel blockers
SVT: Supraventricular Tachycardia
-Same as sinus tach, but bpm >150 and P & T waves look smashed together
-Tx: give adenosine, vagal maneuvers → if doesn’t work then synchronized cardioversion
PSVT: Comes & goes on it’s own, sinus rhythm gets super fast then returns to normal
-Tx: vagal then adenosine, beta blockers, calcium channel blockers
ST Elevation = MI
ST Depression = Myocardial Ischemia
