Panic Attacks and Mitral Valve Prolapse: A Mimicker’s Deception?

Saturday, April 24th, 2010
Bill Chandler asked:


A mimicker is a symptom or disorder that fools its victim, as well as medical and psych professionals, into believing he/she is suffering from something other than the true cause of the problem. And the likeness is so striking that the mimicked issue gets all the attention, allowing the real culprit to remain a mystery. Obviously, mimickers can cause all sorts of confusion, as well as unnecessary pain and anguish. One of the major mimickers of panic attacks and panic disorder is mitral valve prolapse (MVP) and mitral valve prolapse syndrome (MVPS).

As always, let’s start with definitions. If the heart’s mitral valve is functioning properly, blood flows from the left atrium to the left ventricle in a very tidy manner. And that’s because blood is prevented from going back into the left atrium by a tight seal formed as the mitral valve closes. But if one has MVP the flaps of the mitral valve allow small amounts of blood leakage because the valve flaps don’t close evenly; one, or both, collapsing backward.

The physical manifestations of MVP may include heart palpitations, atrial fibrillation (the atria, the heart’s two small upper chambers, quiver instead of maintaining a normal rhythm, resulting in blood pooling and clotting because healthy pumping is interrupted - a stroke may ensue if a bit of blood clot breaks away and lodges in a brain artery), fainting, chest pain, and shortness of breath. MVP, a common and generally benign condition that presents in women three times more than men, is a genetic disorder typically confirmed by an echocardiogram. The only real potential for trouble is the very remote possibility of contracting an infection called endocarditis (an infection of the inner lining of the heart, the endocardium, and the possibility of blood clotting).

Now, here’s where things start to get panic-interesting. Just as a percentage of panic attack sufferers become panic disorder sufferers, so it is with MVP. Some 40% of patients with MVP also have something known as dysautonomia, an imbalance of the autonomic nervous system (ANS), which would indicate neurotransmitter and hormonal confusion as well. Well, the ANS has two components, the sympathetic and parasympathetic nervous systems. The sympathetic nervous system has the responsibility of ramping-up our biochemistry as our fight/flight response is switched on; and the parasympathetic nervous system returns our biochemistry to a state of normalcy as the threat is gone.

Indeed, an incredible number of bodily functions are directed by the ANS and when this system is out of balance the physiological results can be, as you may already know, panic attacks, anxiety, fatigue, migraine headache, irritable bowel syndrome, and many more little goodies. Well, when the situation becomes this complex one is said to suffer from mitral valve prolapse syndrome (MVPS). And it’s estimated that 40-60% of MVPS sufferers will experience panic attacks.

Are you saying to yourself, “Hmmm?” If you have ever suspected you suffer from mitral valve prolapse, or if members of your family have been diagnosed, please get to a doctor and have an evaluation. And even if you don’t have a family history, get tested anyway. A diagnosis of mitral valve prolapse or MVPS, and appropriate treatment, could dispose of your panic attacks and save you a whole lot of aggravation.

Indeed, perhaps you suffer from mitral valve prolapse or mitral valve prolapse syndrome, not panic. Women - are you paying attention?

Do the atria Contract?

Thursday, April 22nd, 2010
Cooler asked:


If so, show me a detail medical reason for this phenonmenon. Why doesn’t the Atria have a valve to prevent back flow if the atria do contract. Where does the blood go? What is the mechanism of atrial contraction ?> Please give a most detailed as answer as possible. I need to proove this to a fellow classmate who refuses to believe the atria contract, he says its not possible because if the atria contract blood will flow back as there is no valve that sepeates the atra from the vena cavas.

What’s Happening in My Heart During Atrial Fibrillation

Thursday, April 22nd, 2010
Ben Escomm asked:


In this article we are focusing on the heart itself and what is actually taking place in the chambers during afib. But first lets go to a normal heart for a second.

In a normal heart we have a “lub-dubb” sequence. If you’re not familiar with what I’m talking about, you can find a full explanation on my website but here’s a quick description so you get the idea:

The top part of your heart (atria) squeezes and makes a “lub” sound, then the bottom part of your heart (ventricles) squeezes to give the “dubb” sound. “Lub-dubb” is the sequence that comes from one beat of the heart.

Now that’s outta the way, on to the rest of the article:

The lub is created by a electrical pulse in the right atrium (right upper chamber). See, the heart has its own natural pacemaker called the SA node-its basically a part of that chamber which automatically fires an electrical pulse that causes the heart to contract or squeeze-first in the atria (lub) and then in the ventricles (dub). The SA node controls the rate at which the heart beats in a normal heart.

In a heart with atrial fibrillation the electrical pulse that is fired from the SA Node isn’t the only pulse fired. There are other sites in the right atrium called foci (plural for focus) that are firing pulses as well. These other sites are firing faster and at the same time as your natural pacemaker causing multiple contractions of your upper chambers, which is why, during afib, the atria looks like jello quivering (lublublublllubuubllublub) as opposed to a single unit making a single squeeze (lub).

Its these multiple pulses from the right atrium which cause the ventricles (and therefore your heart rate) to be irregular…and, as you recall it’s the AV node which helps slow the rate of contraction from the atria to the ventricles.

What is premature atrial contractions and is it serious?

Friday, April 16th, 2010
millerc3 asked:


I was just told that I have this condition following an EKG I had done. I’m only 24 years old and it scared me. I would like to know how serious it is and how likely it is for me to have blood clots and have a stroke (like I was told is very possible).

I have no idea what do do i am 11 my dad is 41 and he has some health issues like pac’s (pre atrial contraction’s) but that’s it But i am worried he has these things called floaters they swirm around in his eyes and make stuff blurry. He HAS gone to the eye doctor and they ALL said there is nothing they can do he just has to life with it I do not believe that. He does not have retinal detachment or lime deices.

Does anyone have tips on how to sleep with PVCs or PACs?

Thursday, April 8th, 2010
dwg1998red asked:


Premature atrial and ventricular contractions are considered harmless by the 3 doctors and 2 cardiologists I’ve seen, but what a pain in the ass! Those of you who are as unfortunate as me to actually feel every single one of them, how do you cope? I can’t sleep, and then being tired makes them worse. I take atenolol, but it doesn’t seem to do much. Does anyone have any favorite medicine to control them or sleep through them?
