Term
|
Definition
| non-rhythmic heart rhythm. results from abnormalities of the SA node, or a problem with conduction. |
|
|
Term
|
Definition
| pulse few then 60\min. and not consistent. blood pressure lowers and it can cause less blood to get to the brain and thus pass out. |
|
|
Term
|
Definition
| When pulse is more then 90\min. and not consistent. |

Term
| Sinus node dysfunction causes |
|
Definition
| sinle amiloidosis, hypothyroidism, advanced liver diseases, hypothermia, infectionus diseases, sever hypoxia, hypercapnic, acidosis, vasovagal syncope(lowers heart rate and causes faintness) |
|
|
Term
|
Definition
different organs undergo change that causes disruption in their function.
מטופלים האלה מועמדים להשתלת קוצב לב בדרך כלל בגלל שיש להם ברדקרדיה בגלל שהבעיה קשורה לחשמל |
|
|
Term
| malabsorption of kidneys causes: |
|
Definition
| people to have bradyarrhythmia and this raises the acidosis (lots of acid in the blood) |
|
|
Term
| who are most likely to have a problem of the SA node? |
|
Definition
| elderly people because their body becomes more fibroti and less flexible |
|
|
Term
| "sick sinus syndrome"-SSS |
|
Definition
| sinus node disease that leads to symptoms due to a slow heart rate. most common reason for implanting a permanent pacemaker. |
|
|
Term
|
Definition
| a blockage of the electrical impulse in the atria that stops from reaching the ventricles. (between the SA node to the AV node, bundle of HIS and bundle branches). |
|
|
Term
| block in the bundle of his will lead to: |
|
Definition
|
|
Term
| right bundle branch block will lead to: |
|
Definition
| causes an uneven constriction of the ventricles, then 2nd ventricle will get the signal in delay. you can live long with one bundle brunch blocked. |
|
|
Term
| why do patients with bradyarrhythmia receive pacemakers and some don't? |
|
Definition
| if we can't fix the problem and the patient has symptoms then he will receive a pacemaker, but if we fix the problem that causes the lower heart rate and the patient is a-symptomatic then we will give a temporary pacemaker and follow his recovery. |
|
|
Term
| how does a pacemaker look on a EKG? |
|
Definition
| the complex QRS will have a straight vertical line instead of a sloped line. |
|
|
Term
| Supraventricular tachycardia (SVT) |
|
Definition
| usually not fatal, and problem is a disturbance above the bundle of his (atrium area) that can cause passing out, heart beats and hard of breathing. usually a born problem. |
|
|
Term
| Ventricular tachycardia (VT) |
|
Definition
| usually fatal, disturbance below the bundle of his. |
|
|
Term
|
Definition
| electrical impulse is established that spins continuously between the atria and the ventricles, thus causing one for of SVT. |
|
|
Term
|
Definition
| a syndrome that is connected to SVT |
|
|
Term
|
Definition
| sometimes fetus material don't dissapear in the heart, and then the electrical impulse passes in two cycles instead of one. usually in young people. there are fast signaled fibers, and slow. the electrical impulse will prefer to go through the fast, but if the AV node is not ready it will pass through the fetus cycle and thus back and forth through the ventricle causing the impulse to only reach the ventricle |
|
|
Term
| How to fix the fetus cycle in SVT disturbance? |
|
Definition
1. electrical shock
2. taking out the line that causes the fetus cycle
3. the heart produces an added electrical signal that stops the fetus cycle. |
