Snow on the ?, Smoke over ? and ? in the middle.
The brown lead goes in the ? of the chest at the ? intercostal space at the right ? boarder. |
grass, fire, mud,
middle, 4th, sternal |
|
|
A single lead by itself shows ? and ? and time to conduct an ?
|
rate & regularity,
impulse |
|
|
A single lead cannot indentify or locate an ? It cannot indentify ? deviation or chamber ? It cannot identify ?-? differences in conduction. It cannot show the quality or presence of ? action.
|
infarct,
axis, enlargement, right to left, pumping |
|
|
No ekg strip can tell us about ? action, it can only tell show us the ? signals.
|
pumping,
electrical |
|
|
Only Mechanical action from ?, ? can tell us about pumping action.
|
pulse,
BP |
|
|
ECG paper tells about ?,?,?
|
TAD,
Time Amplitude, Direction |
|
|
The SA node is the ? of the heart it makes the heart pump at ?-? bpm. If the SA node is not firing the AV node will take over and fire a ?-? bpm. If the SA and AV nodes are not firing then ? cells will take over and the heart will fire from ?-? bpm. Any of these cells can take over and cause rapid ? beats.
|
pacemaker, 60-100bpm,
40-60bpm, ventricular, 20-40bpm, irregular |
|
|
Normal time intervals:
P-R =? QRS=? Q-T= ? |
0.12-0.20,
0.08-0.11 (<12), 0.33-0.42 |
|
|
The systematic approach to reading EKG is:
Is there a regular ?, What is the ?, Is there a ? wave and are they the ?, measure the ? interval to see if it is WNL measuter the ? interval to see if it is WNL |
Rhythm,
Rate, P, same, P-R, QRS |
|
|
Dysrhythmias that originate in the SA node:
Sinus ?, all reading WNL except Rate is >100 & ?&? are smooshed together. Sinus ?, all readings WNL except Rate is <60 Sinus ?, is when the HR ↑ or↓ with breathing. |
Sinus Tachycardia,
Sinus Bradycardia, Sinus Dysrhythmia |
|
|
Dysrhythmias originating in the Atria:
Premature atrial ?s which are not usually a problem Paroxysmal ? tachycardia Rate ?-?, Suddenly starts and stops is the meaning of ? Atrial ?, Pwaves are called Fwaves and can be caused by Rheumatic ? disease, ?, ? Atiral ? has no Pwaves and no ? line there is just atrial ? |
contractions,
supraventricular, 150-250bpm, paroxsymal, flutter, heart, ETOH, hyperthyroidism, fibrilation, isoelectric, quiver |
|
|
Premature atrial contractions: happen when one ? cell takes over for 1 beat in the ?
The rate depends on underlying ? Rhythm is usually regular except for the ?, Pacemaker site is an ? site in the Atria, Pwave occurs ? than expected, PR varies dependent of foci of ? QRS is usually ? |
irritable, atria,
PAC(Premature Atrial Contraction), Ectopic, earlier, impulse, WNL |
|
|
Paroxysmal Supraventricular Tachycardia:
Rate=>?-?, Rhythm= ?, Pacemaker site is outside the SA node firing at the ? node. Pwaves are often buried in the preceding ? wave. PR and QRS are usually ? |
>150-250,
AV node, Twave, WNL |
|
|
Paroxysmal Supraventricular Tachycardia:
We know that it is firing above the ventricle at the AV node because the ? complex is there so the electrical signal must have gone down the ? |
QRS,
Bundle Branch |
|
|
S/S of SVT include ? cyanosis, pt will not ? well.
TX= ? stimulation, RN's are not allowed to initiate this Tx. This includes ? massage, have the pt bare down like having a ?, or apply pressure to the ?s |
circumoral, feel,
Vagul, Carotid, BM, eyeballs |
|
|
Meds for SVT= ? , ? , ?
|
Diltiazem(Cartizem)
Beta Blockers, Adenosine(Adenocard) |
|
|
Adenosine(Adenocard) slows conduction through the ? node and interrupts ? It will not convert ? or ? its only good for SVT. It is administered ? via IVP, followed with a ? flush, it has a ? half-life.
|
AV node,
re-entry, Afib or A-flutter, rapidly, saline, short |
|
|
Side Effects of Adenosine(Adenocard) include:
Causes a brief period of ?, It Rarely causes ?, It also causes ?, ?, ?, ?, ?, ? |
Asystole,
Chest pain, Flushing, HA, Dizziness, Nausea, SOB |
|
|
Dysrhythmias originating in the Atria: Atrial Flutter:
Rate = Atrial ?-?, Ventricular rate ?s, Rhythm = ? Pacemaker site is ? Pwaves = ? waves are present, PR= Can't read, QRS = ? |
Atrial =250-350, Ventricular=varies,
WNL, Atrial, Fwaves, Can't read it, WNL |
|
|
TX for ATrial flutter: A flutter is a concern it can cause ? which can lead to death.
Meds: ?, ? Cardio ? can be a tx, or electro-physiology ? |
RVR,
Diltiazem(Cardizem), Amiodarone, Cardio-version, electorphysiology ablation |
|
|
A fib: Rate= Atrial rate= ?-?, Ventricular ?s,
Rhythm is irregulary - ?, Pacemaker is the ? node Pwaves = non ?, Pwaves are present. PR= ? QRS= ? |
350-750, varies,
irregular, AV, discernable, NONE, WNL |
|
|
With Afib we want to get the rate controlled to < ? with activity and < ? bpm when resting.
Tx = Cardio-? , Warfarin(?), EP-? |
110bpm, 80bpm,"",
Cardioversion, Warfarin(Coumadin), EP ablation |
