Stressed heart (HTN, valves CAD), hyper-sympathetic (thyrotoxicosis, Etoh), lung stress to heart (COPD)
19
Q
How to treat AFib?
A
Keep rate slow, prevent clots, convert rhythm.
Funnel drugs- beta blockers, calcium channel blockers, dig
Anticoagulation- heparin, Coumadin, lovenox, xarelto
Convert rhythm before anticoagulant of unstable, or have had AFib

Adenosine (d for down) or vagal maneuvers
23
Q
VTach treatment
A
Bon Jovi rhythm- is the pt dead ( no pulse) or alive (pulse).
Alive, ok-no funnel drugs because it’s a v rhythm not through AV nose. Use amiodarone.
Unstable but pulse present- cardiovert
Dead- defibrillate

squeezed heart or lung (tamponade or tension pneumo)... Needle these
others are
HEAD
Hypothermia, electrolytes, acidosis, drugs

32
How do you treat hyperkalmia acutely?
Calcium will stabilize the cell membrane- give this if ekg changes, it will give you 30 mins.
Bicarbonate will push potassium into cell by causing metabolic alkalosis. Insulin will do this because k will follow glucose. High dose Proventil (neb) also works.
