|
pos (neg) inotropic drugs
|
|
|
drugs that inc (dec) heart hrate
|
pos (neg) chromotropic drugs
|
|
|
drugs that accelerate (slows) conduction of heart
|
pos (neg) dromotropic drugs
|
|
|
What are teh effects and indictions for Cardiac glycosides?
|
digoxin
1. inc contractility (pos inotropic effect) --> Hf 2. regulate rhythm and conduction --> atrial fibrillation |
|
|
What is important to assess before administering Digoxin?
|
assess pulse
hold if: <60 adults <70 children <100 infants |
|
|
Why is it immortant to monitor I&O for patieths receiveing digoxin
|
digoxin toxicity levels are close to therapeutic
therapeutic = 0.5-2 toxic = >2 |
|
|
What prevents absporption of digoxin

|
digoxin Fab - antibody
|
|
|
Suspecct digoxin toxicity. What to do first?
|
1. hold dose
2. notify physicion 2. expect serum digoxin levels ordered 3. expect digoxin Fab order |
|
|

2. variant - occurs at rest or during sleep 3. unstale - intermittent pain severe |
|
|
What is primary drug to treat angina? how does it work?
|
nitroglycerine
relaxes sm. muscle --> vasodilation, lower BP, dec workload of heart |
|
|
what works better for acute angina - topical or sublingual?
|
sublingual is faster
topical slower - more preventative |
|
|
these drugs are used in prophylaxis of angina
