Congestive Heart Failure (CHF)
Heart failure accompanies by congestion of body tissues
complicated by pulmonary congestion or systemic congestion
Symptoms of CHF
Tachycardia
Increased PVR
Cardiomegaly
Sodium and water retention by kidneys
Goals of CHF therapy
Decrease Na and H2O retention
Decrease systemic O2 demand
Decrease preload and afterload
Improve conractility
Drugs used to treat CHF
Inotropics (cardiac glycosides and bipyridines)
Diuretics
Vasodilators
Action of Digitalis Glycosides
Slows rate of ventricular contraction
Increases force of contraction
Increases stroke volume
increases cardiac output
Contributing factor to digoxin toxicity (electorlyte)
hypokalemia
Important drugs for digitalis glycosides
Digoxin
Action of Digoxin
therapeutic effect on electrical activities of the heart
Factors leading to Digoxin Toxicity
electrolyte imbalance
acid base imbalance
renal or liver disease
dehydration
Adverse Effects of Digoxin
Cardiac: Ventricular bigeminy or trigeminy (Initial sign in adults)
AV block (initial sign in children)
