Question | Answer |
---|---|
what results in 80-90% mortality rate even with the best care possible | cardiogenic shock |
what drug is contraindicated in the treatment of cardiogenic shock | Inderal (propranolol) |
the amount of blood ejected by the heart in one cardiac contraction is known as | ejection fraction |
the pressure in the ventricle at the end of diastole is known as | preload |
what is the equation for blood pressure | SV x HR x SVR |
During ventricular systole which valves open | aortic |
the electrical pathway | 1,SA 2.inter nodal pathways 3.AV 4.bundle of HIS 5. bundle branches 6. purkinje fibers |
The sympathetic receptors that are located in the blood vessels and responsible for vasoconstriction | alpha 1 receptors |
the cardiac contractile force is called | inotropy |
the heart sound heard by closure of the AV valves is | S1 |
a junctional escape rhythm originates from the | AV node when the SA node is firing at a slower rate than the AV |
an infarction that involves the entire thickness of the myocardium | transmural |
What rhythm requires trans cutaneous pacing | 3rd degree AV block |
the time an impulse takes to travel from the atria to the ventricles is known as | PR interval |
a normal QRS lasts | 0.04-0.12 secs |
the absolute refractory period is from the | beginning of the QRS to the apex of the T wave |
to perform standard TCP, set the demand rate to | 60-80 bpm |
V-fib can | 1.mimic artifact on the monitor 2.may produce a peripheral pulse 3. should be treated with early defibbrilation |
when initiating TCP in a pulsing patient you should begin with the mA output set at | the minnimum setting 0 |
Hypokalemia treatment | transport |
treatment for RT sided heart failure | fluids |
Hyperkalemia treatment | calcium chloride/sodium bicarb/insulin and glucose |
A goal to treat left ventricular failure is to | decrease myocardial oxygen demand |
this disease leads to: organ engorgement,venous distention,pitting edema,ascites and or pericardial tamponade | right ventricular heart failure |
which arrythmia is commonly associated with sudden death | V-fib |
a sound produced by the body to protect the lungs during LVHF | Wheezing |
BP on the left arm and hard to read on the right, patient is suffering from | a dissecting ascending aorta |
sharp tearing pain between the scapula, patient is suffering from | dissecting aneurysm |
pain comes on suddenly and is 10 from onset | aneurysm |
pain usually lasts 3-5 mins but can last up to 15 mins | stable angina |
pain may come on gradually and build with intensity over the time with resulting irreversable tissue death | myocardial infarction |
pain is usually found in the lower back or flank region it can radiate to the thigh, groin and perineum | aneurysm |
pain usually comes on at rest it can be relieved over time by O2 rest and nitro | unstable angina |
the greater the venous return, the greater the preload, the greater the force of contraction and the greater the stroke volume is describing what | Starlings law |
Atrial systole force is determined by | preload and stretch of ventricles |
LVHF signs and symptoms | resp distress,apprehension,cyanosis,diaphoresis,resp acidosis,rales,rhonchi,wheezing,JVD,altered,HTN,CP,tachy/irregular,tachyapnea |
Cor pulmonale | HTN in the lungs which causes right ventricular hypertrophy |
the cell is negative on the inside compared to the outside | resting potential (polarization) |
K+ movement out of the cell starts this phase | repolarization |
This phase is responcible for muscle contraction | action potential (depolarization) |
cell is considered the most positive on the inside compared to the outside | action potential (depolarization) |
small box represents | 0.04 sec |
a large box represents | 0.20sec |
