A squeaking heart - page 2

:kiss Several months ago, I purchased my own sphygmomanometer and stethoscope to practice, when ever and on & whoever would let me take their BP to get good at it. It's such a cool thing to take... Read More

    It's not chest hairs, jeez. In my bedroom, in the morning, with no distractions, I am very atune to the sounds.
    Although the responses here have been very insightful, I will now tell you my "gut" interpretation of this.
    Heart muscles are in spiral bundles. The sound is like a "rubber band on a seesaw" if you have the imagination. The heart is a "functional syncytium." The cardiac muscles are regulated by the autonomic nervous system. When you sleep (and have nice dreams) I am imagining the heart gets the red light to slow down. I imagine that, an awake heart runs on 100% of the cells contracting, but when you sleep, a percentage of them are not needed, for several hours, so they go inactive, yet are connected. The SA node may not have the same "voltage" when you are asleep. All this contrbutes to sleep. And I think my brain/body knows when its gotta get a good sleep, and lets my heart relax.
    The sound, I believe, in my heart, the hiccup/squeak, is the intercalated disks which are relaxed during sleep, and the plasma membranes re-energizing to full potential power. The chordae tendons tighten but the heart is relaxed from a sleep where some of the cells have fallen asleep too (with the go ahead to do so from the sympathetic and parasympathetic neurons, brought on by sleep), and it takes a stretch to stretch them. Until those tendons stretch, they make a sound.
    It sounds like a rubberband that is taunt, getting stretched till the sound goes away.
    Now my calling in life is to have a one-night-stand with a cardiac doctor and after she tells me about the sound she hears first thing in the morning, thats it, were through :-) Or i can spend the night in a hospital and have a cardiac doctor at bedside when I wake up. I'll let this go, thank you all again!!! And if anyone has anything else to add, i'd love to read.
    sincerely

    "My Squeakin' heart" could be a country song.

    Mario,
    Good education on hearts. You need lots of time to absorb, but it is wonderful. http://www.pacep.org/ since the heart works on the theory of automaticity; all cells must work like dominos. They just don't work as hard when you sleep. free site

    Mario, the heart doesn't run at 100% capacity unless the body is extremely stressed. The heart's normal "Ejection Fraction" is usually around 60%. That means that in a normal waking state, the heart only pumps at 60% of its' capacity because we need a cardiac reserve in order to handle walking upstairs, or running, or even having sex. Anything that increases the heart rate or how hard the heart muscle contracts will increase the work of the heart. The heart doesn't squeak when it works normally.

    A little bit of knowledge is indeed a dangerous thing. Instead of asking for advice on a BB like this........ my suggestion would be to GO TO A DR. OR NURSE PRACTIONER with any MEDICAL concern. Let's face it, none of us can hear it, see you or give a proper evaulation. But, it is one way to get attention.

    I like the song idea, instead of "Your cheating heart," make it

    "Your squeaking heart.....will tell on you....you'll try and try....to make it new....but valves and discs....they wear out too.....your squeaking heart....will tell on you"

It sounds like the kinds of answers I'd, one day, like to belt out to someone who asks me a similiar question. I'll print your responce, and then try to draw a picture of a sleeping heart, with he information you have so wonderfully given. Really, how did you know these answers so well?
    Some of it is from experience, some of it is from studying, a lot of it is from asking questions. We are all continually learning.

    Damn Hoolahan ! That is an excellent rendition of Hank Williams, Sr. What about: "How can I free my sleeping mind, and awaken my squeak, squeakin' heart"
    Yes: "Owner of a squeakin' heart, much better than a owner of a growling heart"
    Neil Young - (harmonica intro) "it keeps me searching for a heart that squeaks - and i'm getting old - i've been a miner for a heart that squeaks"

    SICU Queen - Time is not an object you can have more or less of. You can't possess time; Time is a sense. You can't store time in a bottle. You can't give time. You can experience time. There is no way I can "have" more time than you, or anybody. We all experience time at exactly the same rate. Our senses can not come near the speed of time, which is, the speed of light. Meet me tonight and the nearest event horizon, and I'll show you :-)

    Rod Stewart - "Young Turks"

    "Young hearts, they squeak this morning, time is on your side, don't ever squeak them down, don't let them squeak you around, don't ever let them squeak your point of view......Because life is so brief, and TIME is a thief, when your undecided....and like a fist full of sand it can sift right through your hands.....yeah!....Young hearts, they squeak tonight!!!!!:kiss
