Pulseless electrical activity is a very disconcerting emergency medical scenario with very high mortality unless its etiology can be quickly ascertained and corrected. A mnemonic to remember the different causes of pulseless electrical activity is:
MAD (triple H) CAT
M: massive pulmo...
A mnemonic to remember the most important congenital heart defects associated with cyanosis is:
T: tetralogy of Fallot (TOF)
T: transposition of the great arteries (TGA)
T: truncus arteriosus
T: total anomalous pulmonary venous return (TAPVR)
T: tricuspid valve abnormalities...
A useful mnemonic to remember the differential diagnoses associated with right-to-left cardiovascular shunts is:
1: a combination vessel; truncus arteriosus
2: number of arteries involved; transposition of the great arteries
3: "tri-" means 3, the number of leaflets involved; t...
This mnemonic will help with the sonographic approach to the critically ill patient with dyspnea:
C: collapsed lung (pneumothorax)
absence of anterior lung sliding, lung pulse, B-lines, or z-lines
these artifacts arise from the pleural interface; their presence would rule ou...
A mnemonic for surgically-created cardiac shunts for congenital heart disease is:
Great Flow Really Would Be Perfect
The mnemonic is ordered by the position of the shunt antegrade to normal blood flow through the heart, proceeding from the systemic venous system into the right heart, and then...
A mnemonic for the underlying anatomic defects in tetralogy of Fallot is:
P: pulmonary stenosis
R: right ventricular hypertrophy
O: overriding aorta
V: ventricular septal defect
