V Fib Arrest
Alive vs dead: Simply put, you can live with Afib but not with vfib. both are irregular heartbeats but Afib is a very common irregular heartbeat that many live with daily without worry. V-fib on the other hand is not able to sustain life and is the dramatic moment on TV where you might see patients shocked by defibrillator. ...Read moreSee 1 more doctor answer
Zero: In ventricular fibrillation, the heart is not beating at all - there is an uncoordinated quivering of the heart muscle without any effective contraction. V-fib leads to irreversible death within a few minutes. Immediate treatment (with an aed, automated external defibrillator) can convert v-fib to a rhythm that allows the heart to beat and restores the circulation. ...Read more
VT vs VF: VT: an organized rhythm arising in the ventricle. VF: a disorganized rhythm with no effective pumping. Depending on various factors, VT may be tolerated for long periods. In some cases, VT is not tolerated or degenerates into VF. VF results in death in a few minutes. ...Read more
It can: Rhythm changes can occur rapidly in a code situation. V. Fib can degenerate into asystole. ...Read more
Just had a nuclear stress test done and they just saw v fib happen is that a normal reaction to the cardio lite they used for the images?
If a person who is unconscience from V-Fib and receives defibrillation within 4 minutes, do they have a good chance of survival?
How can you tell the difference between v-fib or v-tach and asystole or pea with no electrical equipment? Basically, shockable vs nonshockable.
See ACLS: Number one you will not shock on your own unless you are trained. But basics wise, all of the above in all likelihood the person has a sudden death, and has no pulse or BP obtainable except may be early and slower v-tach. Again qualified personnels are the ones who would administer shocks. If someone needs a defib, an implantable one should have been placed. ...Read moreSee 2 more doctor answers
AF vs vf: Good question, they could look alike on ECG. Both would also result in cardiac arrest. As no perfusion would result, one would expect AF waves to be less visible than VF very quickly. If arrest had been present for say more than 30sec. , VF would be more likely as the AF waves should likely not be visible. ...Read more
Can you tell me if atrial fibrillation with ventricular standstill is recognized from fine v-fib?
Afib/vfib: ventricular standstill and fine v-fib are functionally the same the ventricle is not contracting - vfib is a slight quivering which may or may not be identifiable on ECG; if the ventricle is not contracting then it is not possible to non-invasively identify atrial fibrillation from simply sinus/atrial arrest. ...Read more
I get ekgs very often & my qt interval is usually 380-430. Today my heart rate was 70 but qt was 338. Is that shortened? Will i go into v-fib?
QT varies w/ HR: Your qt interval will vary w/ your heart rate, as well as certain electrolytes and medications. Yours is in the normal range, deadly arrhythmias usually occur when the qt is too long, not too short, so unless there is some other reason to be at risk for v. Fib., like structural heart disease, your risk should be low. ...Read moreSee 1 more doctor answer
Lightheaded, heart fluxuates but always below 100 but above 60. Have passed all heart tests but dwell a lot. Any risk for v fib? 20 and clean for all
Is a v fib, where the bottom of the heat flutters and the blood does not go to the rest of the body, considered a heart attack?
No: Ventricular fibrillation is a type of arrhythmia (abnormal heart rhythm) that can result from a heart attack. A heart attack implies a blockage of one of the coronary arteries resulting in lack of blood supply (and oxygen) to a portion of the heart. However, ventricular fibrillation has many other potential causes. ...Read moreSee 2 more doctor answers
Had a heart attack in july. had an echo after 3.5 months. EF was 35%. not improved.1 v-fib of 5 beats. says I need defibrillator. do I?
Yes!: More than 3 months out from MI without improvement and V.Fib episodes are certainly indications for an AICD. Sounds like your Cardiologist knows what he/she is doing. I'd trust the Physicians judgement. If not then please get a Timely second opinion. Sudden Cardiac Death is no joke! Wish you well! ...Read more
History of AVNRT. Successful RF ablation. Having short runs of non-sustained palps. Quick flutters of 4-5 beats in <1 second. Scared to death of V-fib?
Avnrt: I think you need to find out first what these pals are about. If they are short runs of AVNRT, you may or may not need another ablation. Cryoablation can be done in a safer way then RF ablation. You can consult me if you want, I am a pediatric electrophysiologist and perform these procedures very commonly. ...Read moreSee 1 more doctor answer
I have a moderate ant of pvcs daily. I see a cardiologist. I'm on toprol (metoprolol) 50 mg xl. Still having them. Am i at an increased risk for v-fib?
Structural disease?: Without structural heart disease PVC is benign and will not generate into vfib. Beside cardiac disease causing PVC there ste other conditions such as electrolyte abnormalities, stress. Sleep deprevation, alcohol, smoking could case pvc. Hope my answer is helpful please let me know if you havd any questions. ...Read moreSee 1 more doctor answer
