What Are Heart Murmurs, Anyway?
Heart murmurs are, in a way, extra or unusual sounds heard during a heartbeat. These sounds happen as blood flows through the heart's chambers or valves, or through blood vessels near the heart. While some murmurs are, quite simply, normal findings, others can point to an underlying heart issue, so recognizing them is a big deal.
For instance, a normal finding in many children and adults is when the aortic and pulmonic components of the second heart sound are heard separately. This is, you know, a split S2, and it becomes less common after about age 55. Knowing what is typical helps you spot what might be out of the ordinary, and that's why mnemonics are so handy.
Why Mnemonics Are Your Best Study Buddy for Murmurs
A mnemonic is, essentially, a memory device that helps you remember large amounts of information, and they are, honestly, incredibly helpful for something as detailed as heart murmurs. They can simplify complex patterns, making them easier to recall quickly, which is pretty important in a clinical setting.
These memory tools, as a matter of fact, make mastering heart murmurs engaging and very effective. They are, you know, like little mental hooks that help you connect new information to something you already know, making the whole learning process much smoother. For example, using mnemonics for heart anatomy and physiology can really help things stick.
Decoding Systolic Murmurs with Mnemonics
Systolic murmurs happen during systole, which is when the heart muscle contracts and pumps blood out. Telling these apart from diastolic murmurs is, quite frankly, one of the first big steps in cardiac assessment. Luckily, there are some really useful mnemonic heart murmurs to help you with this, and they are, in a way, quite memorable.
The 'S' Mnemonic for Systolic Sounds
Here's a simple one: "Ssss s tenotic lesion of s emilunar valve and s eptal defect cause s ystolic murmur." This mnemonic, honestly, helps you remember that stenotic lesions of the semilunar valves (aortic and pulmonic) and septal defects often lead to systolic murmurs. It's a very straightforward way to link the sound to its potential cause, which is pretty neat.
MR. PASS Wins the MVP
Another fantastic mnemonic for systolic heart murmurs is "MR. PASS wins the MVP." This one is, arguably, a bit more comprehensive. It breaks down like this:
- MR: Mitral Regurgitation
- P: Pulmonic
- AS: Aortic Stenosis
- S: Systolic
- TR: Tricuspid Regurgitation (implied by "MVP" which is Mitral Valve Prolapse, but the core is MR, AS, PS, TR for systolic)
So, you see, MR. PASS points to Mitral Regurgitation, Aortic Stenosis, Pulmonic Stenosis, and Tricuspid Regurgitation as common causes of systolic murmurs. This mnemonic, you know, really covers a lot of ground in just a few letters, which is super helpful for quick recall.
Understanding Diastolic Murmurs with Memory Aids
Diastolic murmurs occur during diastole, which is when the heart muscle relaxes between beats and fills with blood. These can be a bit trickier to spot, but with the right mnemonic heart murmurs, you can get them down very easily. Remembering whether a valve disorder manifests as a systolic or diastolic murmur is, in fact, a very important skill.
The Regurgitant Lesions Rule
From the "S" mnemonic for systolic murmurs, you can, quite naturally, also remember that regurgitant lesions of semilunar valves cause diastolic murmurs. This is, honestly, a clever way to use one mnemonic to inform another, creating a more complete picture of valve disorders. It's all about making those connections, isn't it?
MS. ARD for Diastolic Distinction
Just as MR. PASS helps with systolic murmurs, "MS. ARD" is a brilliant mnemonic for remembering diastolic heart murmurs. It breaks down like this:
- MS: Mitral Stenosis
- A: Aortic
- R: Regurgitation
- D: Diastolic
So, MS. ARD helps you recall Mitral Stenosis, Aortic Regurgitation, Pulmonic Regurgitation, and Tricuspid Stenosis as common causes of diastolic murmurs. This mnemonic, you know, provides a very clear and concise way to categorize these sounds, which is pretty essential for accurate diagnosis.
Pinpointing Murmur Locations: Auscultation Mnemonics
Knowing where to place your stethoscope to hear specific heart sounds and murmurs is, quite frankly, just as important as knowing what they mean. The heart has different auscultation areas, and mnemonics can really guide your hand. These are, in a way, your map to the chest.
The APET Mnemonic
The "APET" mnemonic helps you remember the key auscultation areas of the heart, focusing on the locations to listen for heart murmurs, heart sounds, or any abnormal rhythm. It stands for:
- A: Aortic area (right upper sternal border, 2nd intercostal space)
- P: Pulmonic area (left upper sternal border, 2nd intercostal space)
- E: Erb's point (left sternal border, 3rd intercostal space)
- T: Tricuspid area (left lower sternal border, 4th or 5th intercostal space)
This mnemonic, you know, gives you a very clear path for systematic auscultation, making sure you don't miss any important spots. It's a fundamental tool for anyone learning cardiac assessment, honestly.
Ape to Man for Placement
Similarly, "Ape to Man" is another mnemonic that assists a clinician in remembering where to place the stethoscope during a physical examination. It follows the same order as APET, guiding you from the aortic area, across to the pulmonic, down to Erb's point, and then to the tricuspid and mitral areas. This phrase, you know, is quite memorable and helps ensure you cover all the bases.
Unraveling Murmur Characteristics: What to Listen For
Beyond just timing and location, heart murmurs have other attributes that help you identify them. These characteristics, honestly, provide more clues about what might be going on inside the heart. There's a mnemonic, actually, that can help you remember these key features.
This mnemonic, often called "murmur attributes," includes:
- Intensity (how loud it is)
- Location (where it's heard best)
- Pitch (high, medium, or low)
- Quality (like harsh, soft, or blowing)
- Radiation (where the sound spreads to)
- Shape (how the intensity changes over time)
Understanding these qualities, like whether a murmur is harsh, soft, or blowing, and noting its radiation, intensity, pitch, and timing, gives you a very complete picture. This helps differentiate one murmur from another, which is pretty important for accurate assessment.
Beyond Murmurs: Remembering Heart Sounds
While murmurs are extra sounds, the basic heart sounds, S1 and S2, are fundamental. And then there are S3 and S4, which can also be very telling. These are, you know, the building blocks of cardiac auscultation.
S1 and S2 Heart Sounds
S1, the first heart sound, marks the beginning of systole. It's caused by the closure of the mitral and tricuspid valves. S2, the second heart sound, marks the beginning of diastole. It's caused by the closure of the aortic and pulmonic valves. Knowing what valves close for S1 and S2 is, quite frankly, basic but very important, and it helps frame everything else you hear.
The Third Heart Sound (S3)
The third heart sound, or S3, is sometimes called a "ventricular gallop." There's a mnemonic for conditions where you might hear it: "CEMENT." This stands for:
- C: Congestive Cardiac Failure (CCF)
- E: (Not specified in "My text" for E, but implies something)
- M: Mitral Regurgitation (MR)
- E: (Not specified in "My text" for E)
- N: Normal (up to 30 years old)
- T: Tricuspid Regurgitation (TR)
So, you know, hearing an S3 can point to conditions like congestive heart failure or severe valve issues, though it can be a normal finding in younger people. It occurs during heart muscle relaxation between beats, which is pretty significant.
The Fourth Heart Sound (S4)
The fourth heart sound, or S4, is often called an "atrial gallop." There's a mnemonic using "4 H's" for conditions where you might hear it:
- H: Hypertension
- H: Heart Block
- H: Heart Failure
- H: Hypertrophic Obstructive Cardiomyopathy
An S4 typically suggests a stiff ventricle that has trouble filling, often seen in conditions like uncontrolled hypertension. Recognizing these extra sounds, with the help of mnemonics, is, quite honestly, a very powerful diagnostic skill.
Practical Tips for Mastering Cardiac Auscultation
Learning heart murmurs and sounds isn't just about memorizing facts; it's about practice and using the right tools. In my days as a nurse practitioner student, I, too, employed several study tactics to help memorize content for both the certification exam and my NP program finals. Mnemonics were, honestly, a big part of that.
You can study with Quizlet, using flashcards, games, and more, which is pretty helpful. Watching educational videos, like those from "Dirty Medicine," can also provide clear explanations and visual aids, making the learning process much more dynamic. These resources, you know, really bring the mnemonics to life.
Remember, valvular heart disease can cause hypertrophy (thickening) or dilatation (thinning and expanding) of the myocardium in different heart areas. Understanding these underlying changes helps you connect the sound to the physiology. So, combining mnemonics with a solid grasp of anatomy and physiology is, quite frankly, the best approach.

Frequently Asked Questions (FAQs)
What is a mnemonic for remembering heart murmur locations?
A very common and helpful mnemonic for remembering heart murmur auscultation locations is "APET." This stands for Aortic, Pulmonic, Erb's point, and Tricuspid, guiding you to the specific spots on the chest where you should listen for heart sounds and murmurs, which is pretty useful.
How do you remember systolic vs. diastolic murmurs?
A mnemonic helpful for remembering whether a valve disorder manifests as a systolic or diastolic murmur is to use phrases like "MR. PASS wins the MVP" for systolic murmurs (Mitral Regurgitation, Pulmonic Stenosis, Aortic Stenosis, Tricuspid Regurgitation) and "MS. ARD" for diastolic murmurs (Mitral Stenosis, Aortic Regurgitation, Pulmonic Regurgitation, Tricuspid Stenosis). These, you know, are very effective for quick recall.
What makes a heart murmur louder or softer?
The intensity of a heart murmur can be affected by several factors, including the volume of blood flowing through the heart, the speed of blood flow, and the size of the opening through which the blood is moving.
