cardiovascular II Flashcards
what is angina pectoris
deficit of oxygen to meet myocardial needs
what is myocardial infarction
(heart attack) coronary artey is totaly obstructed, atherosclerosis common, myosin and cardiac troponin are elevated
premature atrial contractions
extra contraction
atrial flutter
av nodes delays conduction, ventricle rate slower
atrial fibrillation
causes pooling blood, thrombus at risk
Atriventriclular node abnormalties are known as
heart blocks
heart blocks do
conduction excessivley delay or stoped at AV node/buddle of his
First degree block
Delay atrial and ventricular contractions
Second degree block
Atrial beat dropped (skipping beat)
Third degree block
No transmission
Bundle branch block is a ventricular conduction abnormalities what does it do
Interference with conduction
Ventricular tachycardia is a ventricular conduction abnormalities what does it do
Beats out of sync
Premature ventricular contractions (PVCs)) is a ventricular conduction abnormalities what does it do?
Additional beats, lead to ventricular fibrillation
Ventricular fibrillation, is ventricular conduction abnormalities what does it do?
Cardiac standstill occurs if not treated immediately
What is cardiac arrest?
Cessation of heart activity, flat ECG
