epinephrine and ventricular fibrillation

Single PVCs do not cause ventricular fibrillation in healthy hearts. An arrhythmia known as ventricular tachycardia can cause ventricular fibrillation in some settings, but ventricular tachycardia is not an irregular heart rhythm, and very uncommon in healthy hearts. Omega 3 can be beneficial in arrhythmias, but ask your doctor.

in cases of sudden cardiac death, are they all preceded by ventricular fibrillation, or sometimes the heart simply stops beating suddenly without VF? What about other cases? I mean when the heart stops beating because of any other health issue? Is it always VF the mechanism?

Yes, I did research on ventricular fibrillation, and an implantable cardioverter-defibrillator is the only treatment. I hope that it is not ventricular fibrillation. Although the doctor seems to be stressing that the vasovagal sycnope is caused by postural hypotension because my mom rose from the chair to reach out to turn on the electric fan.

That is an interesting question. It is possible for an EKG to show a rhythym, for example, when the heart is not actually beating. This condition is called electromechanical disassociation. If the leads come off of an EKG the result on the screen is exactly like ventricular fibrillation. Years ago I can testify that some people were inappropriately shocked due to this error. Not in a zillion years would the ER admit that, of course.

ventricular fibrillation is a medical emergency and is a severely abnormal heart rhythm. A person who has a ventricular fibrillation episode will suddenly collapse or become unconscious, because the brain and muscles have stopped receiving blood from the heart. Ventricular fibrillation can lead to death within a few minutes or a few days. The survival rate for a person who has a VF attack outside the hospital ranges between 2% and 25%.

However, it is important to understand that ventricular tachycardia (or ventricular tachyarrhythmias, that is a joint term for ventricular tachycardia, ventricular flutter and to some degree ventricular fibrillation, though almost all the time used for ventricular tachycardia) can manifest in different ways and be caused by different mechanisms, some of them almost completely benign, some of them life threatening.

The doctors need to test the ICD so they will stimulate the heart with electrical impulses to cause ventricular fibrillation, (essentially a cardiac arrest) to make sure that the ICD can detect and stop (defibrillation) the ventricular fibrillation with a shock from the ICD. He will be sedated for this and probably won’t remember much if anything. People commonly mistaken a heart attack as being a cardiac arrest. A heart attack is damage to the heart muscle from a blockage in the arteries.

Rythmol has shown to be more effective in specifically treating atrial fibrillation and ventricular tachycardia than atenolol.

Is it possible to distinguish between atrial and ventricular fibrillation from the symptoms?

The link below your post goes to a doctor's explanation where he states digoxin is used to treat irregular heartbeats. I was on digoxin for a few months following my congested heart failue event. It is my understanding the medication is used to increase contractility of the pumping chambers. My medication for stablizing heart rate is a beta blocker (coreg) and an ACE inhibitor. My research: "Digoxin is contraindicated in patients with ventricular fibrillation.

Positive for inducible nonsustained monomorphic ventricular tachycardia as well as inducible sustained ventricular tachycardia and ventricular fibrillation requiring defibrillation therpapy. 34-year old female. History of one syncopal episode and one pre-syncopal episode prior to diagnosis. Thanks for any light you can shed on my condition. I was beginning to deal quite well with my ICD and heart problem, but lately have begun to worry again.

This article you posted seems to suggest that ventricular Tachycardia is dangerous and deadly and that solution is ICD as well as ablation.

There are quite a few arrhythmias such as ventricular tachycardia, ventricular bradycardia, atrial fibrillation, and a few more (I’m a nurse). I’m going to mention to my cardiologist about it and will let you know what he says.

you should mention that to your primary doctor. ventricular tachycardia can lead to ventricular fibrillation and asystole.

An ECHO may help to evaluate the valves. The basic cause for the atrial flutter and fibrillation and the left ventricular hypertrophy needs to be dealt with. So, don't worry and discuss this with your cardiologist. Hope this helped and do keep us posted.

Atrial Fibrillation with “RVR (rapid ventricular response) this means that the ventricular response rate to the a-fib is so fast that the chambers can’t fill with blood between the beats. No filling, no blood pressure. How did they end up terminating this? When this happend to me, the ER Dr's tried IV Cardizem, Lopressor and Digoxin. All did nothing but drop my bp to 60 palp. Ultimately had to be cardioverted.

25yr male,215lbs.left side chest pain & left arm pain for about 2 yrs now.localized to one spot on the left side of my chest and doesn't reproduce the pain from pressing in the area.seen 4 cardiologist,stress echo,and had echo,event monitor,egk's,and chest x-ray,chest CT with contrast dye,all normal.total245,with tri-256,hdl39,ldl156.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC545059/ Did you click on the provided link that I sent, in the studies (to my understanding) they had what is called "Idiopathic Ventricular Fibrillation", with NO known heart disease and all NORMAL test results. I'm concerned about this happening in me due to all my symptoms.

can everyone please share their experiences of an EP study with me. I know I have posted on here before about similar questions, here is a little reminder of my situation.I'm a 24 yr old male. Echo, stress test, stress echo, holter, and event monitors have all been normal besides "PVC's and a 26 beat run of ventricular tachycardia at 127bpms that self terminated 1.could an EP study and ablation make my v-tach worse or cause it to become dangerous later on in life? 2.

Ventricular fibrillation is very serious. Collapse and sudden cardiac death will follow in minutes unless medical help is provided immediately. If treated in time, V fib and ventricular tachycardia (extremely rapid heartbeat) can be converted into normal rhythm. This requires shocking the heart with a device called a defibrillator.

However, if your heart does not go back into normal rhythm, V-Tach can lead to the deadly ventricular rhythm called Ventricular Fibrillation. If you do not receive immediate medical attention (CPR, De fibrillation) this rhythm is always fatal. Your heart shakes and moves around like a bag of worms instead of beating. Most of the time, with a structurally normal heart, no heart disease or blockage, V-Tach will not happen. That is what your doctor is trying to say.

Also can any of that be what's causing my pvc's, pac's, svt, atrial fibrillation, tachys?? And should i ask for another echo one to compare just to make sure??

Magnesium treatment is a viable therapeutic option when other antiarrhythmic agents fail to suppress ventricular tachycardia, ventricular fibrillation, multifocal atrial tachycardia, atrial fibrillation and supraventricular tachycardia.

Hypokalemia and Ventricular Fibrillation- An ambulance EKG noted abnormal repolarisation with EKG presenting in a sinus rhythm with T wave inversion in leads II & III and a VF with T waves V4 V5 V6 with T wave depression in leadsV4 V5 V6. ER would not look at report. ( I have been in ER twice with hypokalemia (level 2.8). Is this normal with Hypokalemia? Only other health condition epilepsy). Should I be concerned about Ventricular Fibrilation?
