Low voltage criteria on ECG mnemonic

Entire amplitude of the QRS (R + S wave) must be < 5mm in all limb leads or < 10mm in all precordial leads. How do I remember this? Mnemonic!​

Introducing Cardiowesome

Hi everyone, 

As you already know I have started my Cardiology Fellowship this year. I'm going to post a lot of blogs on cardiovascular diseases that might of not be palatable for medical students. Only some of these posts maybe helpful (pharmacology related, EKG ones, and basic pathophysiology of cardiovascular diseases). 

I understand that the majority of my posts will be limited to a specialized group of cardiologists, echocardiographers, emergency medicine physicians, critical care professionals, POCUS users, electrophysiologists, heart failure specialists, and interventional cardiologists.

This is why, I'm introducing a new label on the medicowesome blog called cardiowesome. These are advanced posts targeted for cardiology fellows and trainees.

I hope you enjoy reading them and learning with me.

S' Tissue Doppler Imaging - Derived Tricuspid Lateral Annular Systolic Velocity mnemonic

S’ Wave: Tissue doppler imaging-Derived Tricuspid Lateral Annular Systolic Velocity

S’ value less than 9.5 cm/sec indicating RV dysfunction. Mnemonic... If you stare at the number long enough you'll see 9.5 in it lol. 

The first peak above baseline that is timed with the QRS represents isovolumetric contraction and not the tricuspid annular velocity.

Relative wall thickness 0.42 mnemonic

The RWT reports the relationship between the wall thickness and cavity size. It is an index of LV concentricity. 

The golden number to remember for RWT is 0.42 as it allows further classification of LV mass increase as either concentric hypertrophy (RWT >0.42) or eccentric hypertrophy (RWT ≤0.42). 

Since there are so many numbers to remember in echocardiography, I made a mnemonic for RWT. 

Relative = 0 (Relative zero)

Wall = 4 (4 letters in the word wall)

Thickness = 2 (2 strokes in the letter T) 

Hope this helps!

Variations in clinical presentation of rheumatic/ sydenham's chorea -

Relative wall thickness on echocardiography

Relative wall thickness (RWT) is calculated as two times posterior wall thickness (PWT) divided by the left ventricular internal diastolic diameter (LVIDd). 

RWT allows further classification of LV mass increase as either concentric hypertrophy (RWT >0.42) or eccentric hypertrophy (RWT ≤0.42).

Infective endocarditis vegetations - which side do they develop?

Infective endocarditis vegetations tend to develop on the upstream side of the valve (flow side) which is typically tend to be the lower pressure side. These are the ventricular side of the aortic valve and the atrial side of the mitral or tricuspid valve. 

Image shows parasternal long axis view on echocardiography showing vegetations on the mitral and aortic valve (green vegetations because vegetables are green lol!)

Mitral valve anatomy and types of mitral regurgitation mnemonic

Mnemonic:

Prolapse tip points towards LV

Flail tip flips away from LV

Secondary stay away from each other (dilation)
