Q
What is Oversensing? SENSEOr Failure to PACE?
Undersensing? SENSE failure
Failure to capture? PACING Failure
failure to output? PACING Failure
A
- mistakes a fib, tremor, physical actvitiy for cardiac activity and doesn’t fire when it should. syncope. dropped beats
- spikes in the middle of QRS or after (some spikes with QRS some without). doesn’t sense native cardiac activity=asynchromnous pacing
Capture- pacer stimulus doesnt lead to myocardial contractions - from MI maybe
output failure- not generated when it should

TTP- platelts problem. Vwf WITHOUT inhibtiory DAMST13. platelte plugs with end organ damage. thrombocytopenia, LDH, end organ damage, schisotcytes. GIve 2 units plasma. put in a line, bleeding is rare! go femoral.
DIC: secondary. too much thrombin. consumes factors to make bleeding, but in prothombotic state bc of thrombin, finbrinlysis also in play. D imer up, fibrinogen down, plates down, coags ups. No specific transfusion threshold, you CAN transfuse if bleeding or need procedure. give cryo 10 units if fibrinogen <150, transfuse if getting worse.
d Dimer is product of to fibrin vlots arc welded by factr 13 and fibrninlysis.
thrombin ceanes to make fibrin clot!
62
What can you treat PEs like?
Pulm HTN! inhaled nitric oxide. dont intubate. no fluids.
catheter, vs surgercal, vs medicine clot removal.
go epi and then vasopressin
remember the RV is very suspeiclpte to hypotension and ishcemia- poor RV is a poor LV and CO- look for Interventricular flattening

Sublingual nitro in the mean time!
1.25 mg of IV enalapril - or captoril cn abe helpful
becareful for Aoritc stenosis with high doses of NItor to drop thier afterload!

```
Stat CXR (20% normal),
D Dimer + clinical tool = decent study and usabel to see if CTA needed
US: suprasternal with flap in your vessel
```
If there is anaphylaxis to contrast - intubate them and then CTA and then OR
Tx: consultant coagulaopthy based reversal, 50/50!
Check for tamponade.
control pain.
