A common cardiac dysrhythmia with atrial contractions that are so rapid that they prevent full repolarization of myocardial fibers between heartbeats
|
Atrial Fibrillation
|
A property of specialized excitable tissue in the hear that allows self-activation through the spontaneous development of an action potential, such as in the pacemaker of the heart
|
Automaticity
|
Drugs that influence the rate of the heartbeat
|
Chronotropic Drugs
|
Drugs that influence the conduction of electrical impulses within tissues
|
Dromotropic Drugs
|
The proportion of blood that is ejected during each ventricular contraction compared with the total ventricular filling volume
|
Ejection Fraction
|
When heart cannot pump enough blood to keep up with the body's demand
|
Heart Failure
|
Drugs that influence the force of muscular contractions, particularly contractions of the heart muscle
|
Inotropic Drugs
|
The total amount of blood in the ventricule immediately before contraction? Also called?
|
Left Ventricular/End-Diastolic Volume / Preload
|
Heart Failure can be caused by what 3 conditions?
|
Myocardial infarction, ischemic heart disease, cardiomyopathy
|
Pulmonary edema, coughing, shortness of breath, and dyspnea are signs of what kind of heart failure?
|
Left-Sided Heart Failure
|
Systemic venous congestion, pedal edema, jugular vein distension, ascites, and hepatic congestion are signs of what kind of heart failure?
|
Right-Sided Heart Failure
|
A weakening of the heart muscle which can lead to heart failure
|
Cardiomyopathy
|
Tissue death that occurs due to inadequite blood supply. What is it called when it happens to heart muscle?
|
Infarction / Myocardial Infarction
|
5 drug classes are mentioned for treatment of heart failure? What do all of them have in common? What drug is used if all of these fail?
|
ACE Inhibitors, ARB's, Beta Blockers, Loop Diuretics, Aldosterone Inhibitors / Renin-Angiotensin-Aldosterone System / Digoxin
|
Why is Digoxin the last resort drug for heart failure?
