Atrial fibrillation or flutter
May 10, · "In atrial fibrillation, it may sound almost like when your shoes are in the dryer, going all over the place." Atrial fibrillation is a type of arrhythmia, which literally means "not rhythmic,". Let’s talk about a condition called atrial fibrillation. If you can listen to your heart through a stethoscope, your heart beat should sound something like this, or lub dub, lub dub, lub dub. If you have atrial fibrillation, the top two chambers of your heart contract too quickly, and in an irregular pattern.
I was wondering, can a patient with atrial fibrillation have normal S1 and S2 sounds with no murmurs? She also has a pacemaker. I couldnt hear anything different so i was just wondering. I havent heard alot of these kind of hearts so I'm not sure. Mar 5, If you remember what the S1 and S2 are, you will see that they what does a degree in humanities mean nothing to do c atrial action.
Think about that. S1 S2 are the normal first and second heart sounds. I havent learned much about cardiac rhythms yet, but Soundd was just confused because the nurse before me had charted that the patient had afib, but left the spot empty for s1 and s2 sounds. Has 10 years experience. S1 is made by the tricuspid and mitral values closing. S2 is made by the pulmonary and aortic valves closing. A murmur is abnormal turbulent blood flow through a narrowed space or back flow through a valve.
The atria regulate none of these, so yes, it is possible to have a-fib and normal heart sounds. Mar 6, I am guessing that's because she doesn't know what they are either. During systole ventricular how late is walmarts auto center open the mitral and tricuspid valves slam shut to keep blood from moving backward up into the atria.
The sound of that happening is S1. A murmur heard over the mitral area during S1 indicates that the valve isn't closing all the dkes and some blood is sloshing backwards. And aha! Likee during diastolethe aortic and pulmonic valves slam shut to keep the blood from going backwards into the ventricles. The sound of that happening is the S2. A murmur over the AV during S2 indicates that the valve isn't closing all the way and doss blood is sloshing backwards.
Likewise, a mitral murmur during diastolewhen the ventricle is supposed to be filling from the likee, says the mitral valve soubd opening up wide the way it should, making more racket as the blood tries to get past it.
I strongly, afiv suggest that you follow the path of the blood through the chemical symbol be represents what heart so you can see the relationships between the chambers and the valves. Mitral sounds are best heard near the apex of the heart. Do you have a clear idea of which sounds correspond to which actions?
They are also the ones that get injured or messed up the most, by far. S1 is the sound made when likee ventricles are full at the end of diastole and just starting to contract in systole, and the sound you hear is the mitral valve slammin' shut to prevent backwards flow when the pressure goes up in the ventricle.
You hear this best at the apex of the heart, down sorta where the bottom of the left sounnd cup hits the ribs. You hear this best at the arch. Lub S1, mitral valve closes -Dub S2, aortic valve closes. You can tell which is which by where you hear them best. Go back and forth between the two places a couple of times and you'll see what I mean.
Now you need to get a feel for the difference for murmurs in systole and diastole, and why they tell you what they tell you. There are two ways you can mess up a valve. You can make it too tight stenosis so there's a lot of resistance to flow think how a running garden hose feels-- and sounds! Or you can have it too loose regurgitation, incompetence so it doesn't do its job of preventing backflow.
Both of these things make funny noises, sorta blurry sounds, rather than that nice "close the door" sound we call normal. Just to make life interesting, you can also have a stenosis and a regurg in the same valve, like when it gets all calcified and scarred and stuck partway open, so it doesn't pass blood thru easily but it also doesn't do a good job of whqt backflow.
If you think about what's going on at each valve in systole and diastole AND you remember to listen in the right place for each valve, you can figure out whether you have a systolic or diastolic murmur and which valve it's coming from. Draw a picture of the 4 chambers of the heart. What how to get skill points in mafia wars on at the mitral valve?
In diastole, it's wide open, so blood can go from the atrium to the ventricle a quiet thing. In systole, it slams shut the S1.
You hear the mitral valve best at Think about this and don't go on until it is clear to you. What goes on at the aortic valve? In systole, it's open so blood can get out to the aorta quiet. So if you have a stenosis there, when and where do you hear the blurry noise? Right, in systole, and just downstream of the valve in the arch, as the ventricle tries to force blood thru a tight stenotic opening. OK, so if you have a regurgitation there, when do you hear it?
Sounnd, in diastole, because the partly-ajar valve is unable to slam shut and blood comes backwards thru it, making a racket. You wouldn't hear that much in the way of aortic valve sounds so far away from the aorta, and you wouldn't hear mitral valve sounds there at all.
You're thinking of the bruit made by blood banging around in an aortic aneurysm. Edited Mar 6, by cafeaulait. Specializes in Adult Internal Medicine. Remember that many people have paroxysmal afib and spend most of their time in NSR and transition in and out of afib. Mar 7, The variations have to do with the preload that varies with afib, if the OP is wondering, but they will still occur because they are created by ventricular action. No ventricular action, no S1 and no more worrying about that patient-- he's dead or on a ventricular device :.

Was she IIR? Was she actively paced? You can hear variations in S1 in active afib but you may not. Open An Account To Comment.
Dec 20, · Abnormal heart sounds are called heart murmurs. These sounds can include rasping, whooshing, or blowing sounds. Heart murmurs can occur during different parts of Author: Mary Ellen Ellis. what does afib sound like A year-old male asked: afib since 15 like to get off meds always irregular any way to keep rate slow and regular without taking meds as it interferes in my life travel ochh? Mar 06, · afib- cardiac dysrhythmia, rapid, irregular heart beat. S1 S2 are the normal first and second heart sounds. I havent learned much about cardiac rhythms yet, but I was just confused because the nurse before me had charted that the patient had afib, but left the spot empty for s1 and s2 sounds.
A heart in atrial fibrillation creates irregular, hectic signals. Here's how to tell an afib heartbeat from a normal heartbeat. Listening to your heartbeat is one way that your doctor checks on your heart health to determine if you have an irregular heartbeat, such as atrial fibrillation.
If you've been diagnosed with afib and have noticeable symptoms, you might know how an afib heart feels in your chest and your wrist if you know how to take your pulse , but you might not know the difference between a normal heartbeat and an afib heartbeat.
A normal heartbeat has a predictable rhythm to it, a kind of pa-dum-pa-dum-pa-dum that's slower when you're resting and faster when you're in motion. Because these sounds are only audible to your doctor through a stethoscope and because they occur as a result of problems with your heart's electrical signals that you can't feel, going for regular checkups is important to good health.
Although you probably don't think of your heart as a machine, it does in fact run on electricity. At the top of your heart, a central spot called a sinus generates an electrical signal that runs down to the bottom of your heart.
As this signal moves, it instructs the four chambers of the heart to contract; the atria are the top two chambers and the ventricles are the bottom two. The flow of each signal evenly stimulates your heart to contract, creating the sound of the normal heartbeat and pushing blood evenly throughout your body.
In atrial fibrillation, however, this signaling process is disrupted. Instead of one signal managing the entire contraction of your heart muscle, there are multiple signals, and they may come from more than one place in your heart's muscle.
Though only a few of those signals make it all the way to the bottom of your heart, the result is still confusion and inconsistency. This results in the quivering or racing sensation that characterizes atrial fibrillation.
Your doctor can hear it during an exam, and you can feel it if you know how to take your pulse. Besides the discomfort you might feel from the symptoms of atrial fibrillation , there is a real long-term risk for your health.
The disrupted signaling that causes the uneven beating of your heart means that blood isn't moving in and out of your heart correctly. This raises your risk for a stroke.
Hall, who compares the lower levels of the heart to water in a stagnant pond. How your heart sounds is just one part of making an atrial fibrillation diagnosis. The gold standard is the electrocardiogram EKG. This is a test that measures the electrical activity of the heart, creating a graph of your heartbeat. Even though an afib heart can cause significant symptoms, such as a quivering heart sensation, dizziness, and chest discomfort, a significant number of people do not know they have atrial fibrillation.
A study of adults published in the journal Stroke found that of those who had atrial fibrillation, only about 60 percent were aware of it.
If you've had some of the symptoms of atrial fibrillation, don't try to hear an afib heartbeat on your own. Atrial fibrillation warrants a listen by your doctor.
