Septum is big and thick, portion under the aortic valve is big and thick

68
Q

Sx of Left Ventricular Hypertrophy

A

Exercise induced syncope, SOB, Murmurs

69
Q

How do you decrease the sound of a murmur in ventricular hypertrophy

A

Squatting, Laying Down, Fist Clench, Inspiration
To decrease the sound, you increase the venous flow to the heart
This is because the septum covers the aortic outlet as blood enters the heart chambers

70
Q

How do you increase the sound of a murmur in ventricular hypertrophy

A

Valsalva and Standing
To increase the sound, you decrease the venous flow to the heart
This allows the septum to relax and move away from aortic outlet, allowing flow through and the murmur to be heard

71
Q

What is the first choice for Dx ventricular hypertrophy

72
Q

What are other imaging/tests you can do for ventricular hypertrophy

A

CXR: Normal Heart Size
EKG: LVH, Large QRS, Non-Specific T-waves
Angiography

73
Q

Tx for Ventricular Hypertrophy

A

Beta Blockers
Avoid strenuous exercise
No Inotropes

74
Q

What is Aortic Regurgitation

A

Backflow from aorta to LV

It leads to LV volume overload

75
Q

Sx of Aortic Regurgitation

A

Left Sided HF

76
Q

What murmur is heard with Aortic Regurgitation

A

Diastolic Descrescendo BLOWING murmur heard best at LUSB

77
Q

How can you increase the sound an Aortic Regurgitation murmur

A

Handgrip

It increases backward flow

78
Q

How can you decrease the sound of an Aortic Regurgitation murmur

A

Amyl Nitrate

79
Q

Where does an Aortic Regurgitation murmur radiate to
