Cardiology Flashcards
Heart failure medication having no improvement on mortality
Digoxin
4th line heart failure
- Switch ACEi for sacubitril valsartan if HF EF <35%
- Add hydralazine if Afro-Carribean
- Add ivabradine if HF EF <35% and HR >75
Clopidogrel MOA
Blocks ADP
Aortic stenosis heart sounds
Quiet S2
V5-V6 ST elevation
Lateral MI (Left Cx)
V1-4 ST elevation
Anterior (LAD)
II, III, aVF ST elevation
Inferior (RCA)
Define ejection fraction
The difference in volume of blood at diastole and systole
EF: (EDV - ESV)/EDV
Splitting of the first heart sound, where does this correspond with the ECG
R wave
What is S1
Closure of mitral and tricuspid valves
What is S2
Closure of the aortic and pulmonary valves
Soft S1
immobile mitral stenosis
mitral regurgitation
Split S1
RBBB
LBBB
VT
Ebsteins anomaly
Variable S1
AF
Complete heart block
Loud S2
Hypertension
Tachycardia
ASD
Soft/absent S2
Severe aortic stenosis
Fixed S2
ASD
Wide split S2
RBBB, pulmonary stenosis
Reversed split S2
LBBB
PDA
AS
S3
Caused by rapid filling
MR
VSD
S4
Filling of a stiff LV
LVH
HOCM
Warfarin therapy
- small operation e.g. tooth extraction
Can continue as long as INR not above 2.0
HOCM
Ejection systolic murmur that improves on squatting
Signs of VT rather than sVT on ECG
- AV dissociation
- QRS complex >160ms
- fusion beats
- RSR complex
