Systolic and diastolic murmurs (mnemonic)

A mnemonic helpful for remembering whether a valve disorder manifests as a systolic or diastolic murmur is the following:

Mnemonic

During systole, blood streamsflow past the heart's semilunar valves as the ventricles contract.^1,2 During diastole, somethe opposite actionsones occur, as the ventricles relax and collect the human body'srefill itself with venous return.³ ADifference between systolic murmur contrasts with itsand diastolic counterpart inis that the former murmur results fromis due to flow turbulence, whereas the latter kind emanates fromis due to flow regurgitation.^4,5

The above mnemonicmnemonics listed below colloquially corresponds toforms the expression of "an epic DSI's SD card Makes Tablets Download Swiftly," with "epic" substituted bycorresponds to its phonetic equivalent, i.e., "AP-ic," denoting the prefix that describes apices, e.g., of organs and matching withrepresenting the terms "aortic" and "pulmonic." Worthy of additional note is the fact thatMeanwhile "DSI" is referringrefers to a dual-screen handheld gaming console, e.g., from Nintendo.

Finally, a crucial aspect of applying this mnemonic entails re-positioning the 11 words, hereinafter listed, in a 3 by 3, or 9-cell, table. In the first column of such a table, as well as in descending order, i.e., from up to down, lie the words "Disorder "Nintendo DSi" (corresponding to "valve disorder"), "Stenosis," and "Insufficiency." In this table's second column, and within its first cell, figure the words "Aortic" and "Pulmonic," with "Systolic" and "Diastolic" facing inclusion in this column's second, third, and vertically-positioned cells. In this table's final and third column repose the words "Mitral" and "Tricuspid," in the topmost or first cell, i.e., at row one, along with "Diastolic" and "Systolic" vertically positioned in the column's second and third cells.

A: aortic

P: pulmonic

D: disorder

S: stenosis

I: insufficiency

S: systolic

D: diastolic

M: mitral

T: tricuspid

D: diastolic

S: systolic

ComprehensivelyThese words are then fitted into a 3x3 or 9-cell, table. The first column can be filled from above downwards as "disorder", "stenosis," and in terms of order,"insufficiency." In the listing above presumes that its users will proceed from considering the content(s) of the first cell, and row, of the table's second column, before moving"aortic/pulmonic," "systolic" and "diastolic" can fill up respective rows from above downwards. In the third column, "mitral/tricuspid", "diastolic" and "systolic" can be written from first to all three cells andthird rows ofrespectively.

Referring from the table's first column. After proceeding in the manner heretofore recommended, an application of the table's contentsaortic/pulmonic stenosis would reveal that a pairing of the words "Aortic" and "Stenosis"produce systolic murmurs. Aortic/pulmonic insufficiency would point to (a)produce diastolic murmurs. Mitral/tricuspid stenosis would produce diastolic murmur while mitral/tricuspid insufficiency would produce systolic murmur(s), in the same way that linking the words "Pulmonic" and "Stenosis" does. In contrast, pairing "Aortic" with "Insufficiency," as well as "Pulmonic" with "Insufficiency," would point to a diastolic murmur. As part of a final step, the remaining four words would be positioned such that "Mitral" and "Tricuspid" would be in the first cell, or row, of the table's last column and "Diastolic" as well as "Systolic" would face inclusion in the column's vertically-stacked second and third cells. In consequence, an application of this new consideration would establish that "Mitral" and "Tricuspid" would match with "Stenosis" would manifest as a "Diastolic" murmur.
