| Answer |
|
|
| A normal heart rhythym is called? |
normal sinus rhythym |
| Why is it called sinus rhythym? |
because the electrical conduction starts at the sino-atrial node |
| Rate of normal sinus rhythym is? |
60-100bpm (normal heart rate or atrial rate) |
| Rate of the AV node and bundle branches is? |
40-60 |
| Rate of the purkingie fibers is? |
20-40 (Just remember normal sinus rhythym is 60-100 and it slows down as it goes through the heart. Subtract 20 through the bundle branches and subtract 20 through the purkingie fibers.) |
| Normally the atria (P waves) and the ventricles (QRS complexes) should beat at the same rate? True or False? |
True |
| If electrical conduction begins in the BB or ventricle-What would the rate be? |
40-60bpm |
| A slow heart rate is called? |
sinus bradycardia |
| Rate of sinus bradycardia is? |
40-60bpm |
| Can sinus bradycardia be normal? |
Yes in children or athletes |
| Does normal sinus brady need treatment? |
NO |
| When is sinus brady considered abnormal? |
When there are signs of low Cardiac Output |
| Signs of low Cardiac Output are? |
SOB, reduced LOC, cold, clammy, diaphoretic. |
| Does abnormal sinus brady need treatment? |
YES |
| Causes of Sinus Brady are? |
ICP,vagal stimulation(constipation), hypertrophy, beta blockers, rest/sleep, any disease that damages the SA Node, digoxin, CCB’s (Think Brady If Brad-C Acronyms spell Ivh, Bradc) |
| Med Treatment for Brady is? |
ADE for Brady, Atropine 0.5mg IVpush, Dopamine, Epi (Also hold any of the drugs that cause Brady – Na+ blockers(dig) and BB’s, and CCB’s) |
| If the heart is beating too slow and meds do not correct it what else might be needed? |
Temporary pacing until the cause is found. Or permanent pacing if sinus disease. |
| A fast heart rate is called? |
sinus tachycardia |
| Rate of Sinus Tachycardia is? |
100-150bpm |
| What are causes of Sinus Tachy? |
Infection, Fever, Pain, Anxiety, Caffeine, Hypoxemia, Hypovolemia, y Brady meds (Think Tachy - IF PACHY) |
| A normal heart rate that fluctuates with the Pts. respirations is called? |
Arrhythmia |
| If arrhythmia is suspected what would the nurse do to observe this? |
Observe the rhythm while listening to respirations. |
