Septic pericarditis
Infection of the pericardium that progresses to heart failure & death
What is pericardial effusion?
Excess fluid accumulates in the pericardium
Can be caused by inflammation, infection, or hemorrhage & a # of conditions
What is cardiac tamponade?
What does it lead too?
Fibrous pericardium (out/ no elastic) is overfilled w/ fluid the heart can’t expand normally between contractions
It leads to less complete cardiac filling, decreased stroke volume, & decreased cardiac output
Pericardial effusion w/ or w/out cardiac tamponade may be treated
By inserting a needle into the pericardial sac (usually through chest wall) & withdrawing the excess fluid
What is patent ductus arteriosus? (PDA)
What do they suffer from?
Cure?
Normally, the shortcut opening between the pulmonary artery & aorta known as the ductus arteriosus closes soon after birth.
Occasionally, the opening fails to close in the newborn (PDA)
Young- they suffer from inadequate oxygenation of their blood; in long term- condition incompatible w/ life.
Cure- treated w/ drug therapy to promote closure, or surgical closure of the ductus arteriosus may be an option
“CLEAR” baymax’s monotone said.
What does it mean?
Defibrillation (heart electrical conduction system)
It sends a large electrical current of short duration through the heart, to repolarize all cells at same time
If successful, the SA node & hearts normal conduction system will resume control over depolarization of heart cells after cells have been “reset” by defibrillation
Sometimes caused by an ectopic (out of place) pacemakers & SA node together create currents from diff directions…. Losing synchronized contraction of heart is lost
Or in ventricular fibrillation
CGF congestive heart failure
Common- pumping ability of the heart decreases, usually due to disease of heart muscle or a valve malfunction that restricts the forward flow of blood through a valve that allows a backwards flow
CDF predominantly right or left side?
Either- when right: blood returning from systemic circulation is no longer able to move through the right heart as quickly
So blood pressure in systemic circulation increases, which results in ascite (fluid in abdomen) & edema ( fluid in tissues)
Left: venous return from the lungs is decreased
So pulmonary edema, which interferes w/ respiratory function. Decrease in cardiac output associated w/ heart failure may also reduce perfusion of important organs, such as kidneys, to dangerously low levels
What treats CHF
Medications: cardiac glycosides to increase strength of cardiac contractions, diuretics to promote elimination of extra fluid to relieve edema, & vasodilators to enhance blood flow to the organs & decrease vascular resistance to outflow from the heart
No cure!!!!!!!!!
Just treat-improve life quality
If there are more P wave (aota depolarization) then QRS waves (ventricular depolarization)
Heart block!!!
Not every electrical impulse generated by SA node is being successfully transmitted through AV node to ventricles
