|
|
Atrial flutter |
the atria contract at a rate too fast for the ventricles to match, so the ventricle only actually fires at a ratio of 1:2 or 1:3 of the electrical stimulus coming from the atria. That is why you see the F waves or sawtooth pattern. it usually degenerates into A-Fib. |
|
|
A-Fib |
occurs when many different cells in the atria depolarize independently rather than in response to a stimulus coming from the SA node. |

|
left sided heart failure |
blood gets backed up into the lungs due to weakened left ventricle. the left ventricle doesn't have enough force to push all the oxygenated blood in a single contraction from the left ventricle to be circulated throughout the body. This leads to increased systolic pressure and blood backing up in the lungs. the extra pressure needed to pump blood can damage the right side of the heart. |
|
|
right sided heart failure |
usually happens after left sided failure. hearts pumping mechanism is already damaged and there is increased pressure in the circulatory system. when the right side loses pumping power the blood back backs up in the body's veins causing pedal edema and swelling within the abd. |
|
|
CHF |
After being diagnosed with heart failure, the blood begins to back up in the body and causes swelling of the tissues. as the tissues swell, fluid backs up in the lungs causing pulmonary edema. This causes SOB especially while lying flat and can lead to respiratory distress or failure. |
|
|
causes of seizures (non-epileptic) |
Low blood sugar levels low sodium levels drugs and etoh high fever trauma idiopathic (unknown cause) |
|
|
generalized seizure |
involves the interruption of electrical stimulus in the cells (neurons) within the entire brain. |
|
|
Partial seizure Complex partial seizure |
involves the interruption of electrical stimulus in the cells, effecting only a small portion of the brain. subtal alterations in LOC. |
|
|
tonic-clonic seizure (formally known as grand mal) |
generalized seizure causing convulsions and AMS. tonic refers to stiffening of the limbs and clonic refers to the jerking of the limbs. |
|
|
epileptic seizures |
most common cause of recurring seizures not related to a medical condition. the cause in most cases is unknown, but it is believed that genetic factors play a role. |
|
|
status epilepticus |
>5 minuets of continuous seizure activity. this is a life threatening condition. Medication to stop seizure must be used. |
|
|
