A.
decreased blood flow to the tissue;depressed or inverted T wave
B.
Ventricular repolarizaton
C.
Ventricular depolariztion
D.
VTach. Rate 100-200bpm rhythm regular. no P waves, causes same as PVc Tx: defib. if no pulse, lidocaine or amiodorone and cardioversion if pulse present.
E.
atrial fibrillation 400-700bpm chaotic and irregular rhyth. causes: hypoxia,ischemic heart disease, MI Tx:O2 digoxin, cardioversion, beta blockers
F.
Atrial flutter 250-350bpm Tx:O2, digoxin, cardioversion, beta blockers
G.
Dominant pacemaker with intrinsic rate of 60-100 bpm
H.
tacycardia >101-160 Tx:o2
I.
count the # of R waves in a 6 sec. strip and X by 10. Or do 300 ___ # of large blocks between R waves.
J.
bradycardia <60bpm Tx:O2 and atropine
K.
PVC. rate depends on underlying rhyth. P wave absent. Causes:caffeine, stress, alcohol,acidosis,MI, hypoxemia. Tx:O2, Lidocaine or Amiodorone.
L.
atrial depolarization
M.
back up pacemaker with 20-45 bpm
N.
SA-AV-Bundle of His-bundle branches-purkinje fibers.
O.
Asystole Rate:none rhythm:none Confirm in 2 leads first, Causes: ischemia, infarct. hypoxia,hypothermia, drug od, acute resp. fail. Tx: CPR, epi, atropine
P.
death of tissue; the end result of ischemia or injury.
Q.
atrial and ventricular repolarization, should be at baseline, -Tall or spiked waves=Hyperkalemia,MI -elevation=infarction -depression=ischemia
R.
V Fib Rate:NONE rhythm: chaotic pQRS wav: absent No cardiac output or pulse Causes: acute MI, untreated Vtach,hypothrermia, electrolyte imbalance, electric shock. Tx: Defib., CPR, O2
S.
Acute damage to the tissue often from ischemia; elevated S-T segment
T.
not elevated or depressed.
