Mitra valve
Myocardium-
Endocardium-
Myocardium – heart muscle
Epi means on top
Endocardium- blood tocuhes it
Visceral – covers the
organ
Double-layered serous membrane redudes
friction
Epi means
on top
Pericarditis – inflammory of the
parietal pericaridium usally happens after a virus and PT witll complain of Fatigue Acute
Acute - triad of symptoms
Chest pain
friction rub
ECG changes
Pericardial Effusion
accumulation of fluid in pericardial cavity
Tamponade
Pulsus Paradoxus
30-50ml in sac is normal
Tamponade - increased pressure r/t fluid in pericardial sac so dec cardiac output
Pulsus Paradoxus - exaggerated decrease in systolic BP
Constrictive pericarditis
Fibrous scar tissue
Reduced diastolic As are not filling
Reduced cardiac output
Coronary Circulation
Left Main Anterior descending Circumflex Right main SA node-PACEMAKER* Posterior descending
Coronary Heart Disease
- Atherosclerosis
- Fixed
- Unstable
-Atherosclerosis - most common cause of CHD,Vessel hardening
hyperchoseral
- Fixed - stable - plaques - chronic ischemia-thick
- Unstable –thin- vulnerable - platelet adhesion-marathon perff health runner fall death
Acute Coronary Heart Disease
Unstable Angina / Non-ST-MI
ST Segmental Elevation - AMI – acute heart attack
Can case tissue death
Infactrion – O too low to suply mussle so die
Diagnostic Signs of Acute Myocardial Infarction (AMI)
ElectroCaridoGram changes T-wave inversion ST-segment elevation Abnormal Q wave Serum marker changes- mark MI Troponin assays CK-MB
ST elevation explain
Fluid cant go through tissue cuz of cell death STMI
