What is special about grade VI?
palpable precordial thrill
Murmurs are loudest when heard from:
the apex of the heart
What valves are on the left?
What valve is on the right?
Murmurs are noted based on: GLPT
- point of maximum intensity
- timing (systolic, diastolic, continuous)
To listen to the left valves what should be done?
listen over left intercostal spaces 3-5 times
What should aslo be done while auscultating? HRPC
- heart rate
DX murmur: AREE
- ECG (holter monitor)
ECG measures what?
electrical impulses of the heart
Can there be a normal ECG tracing without cardiac output or pulse?
What 2 views for radiographs?
Tx for acute heart dz: ONF
- Nitroglycerin paste(vasodilator)
- Furosemide (diuretic-Lasix)
Tx chronic heart dz:DFEDPASBCARTA
- antiarrythmic drugs prn
- beta blockers
- calcium channel blockers
- ACE inhibitors
- taurine in cats
- sodium too low
Digoxin is a positive inotrope it _ HR, _ contractility, and has a _ margin of safety.
Pimobendin _ contractility and is a vasodilator.
Antiarrhythmic drugs work by cotrolling the NA flow. What are two examples? LP
Beta blockers are the lol drugs they _ HR.
Calcium channel blockers inhibit contractility and dec BP. Name 3 examples AVD
ACE inhibitors are vasodilators name 3: ECB
Abx are given when?
mitral endocarditis associated with dental dz
ACE inhibitors result in: VDI
- decreased water retention(blocks angiotensin II from binding to activate aldosterone)
- in cardiac output
