How are v-tach and v-fib different?

How are v-tach and v-fib  different?

VT, VF: V-tach is a regular rapid ventricular rhythm which usually has a pulse associated with it. V-fib is an irregular rapid ventricular rhythm which doesn't have a pulse associated with it. ...Read more

What is the difference between A fib and V fib?

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 more

How fast is the hr of a patient who is in v-fib?

How fast is the hr of a patient who is in v-fib?

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

Could you please tell me the difference between vf (v-fib) and vt (v-tach) ?

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

After v-fib, does the rhythm immediately go into asystole?

After v-fib, does the rhythm immediately go into asystole?

It can: Rhythm changes can occur rapidly in a code situation. V. Fib can degenerate into asystole. ...Read more

Does a patient in v-tach, v-fib have a pulse?

Vtach/Vfib...: A person in ventricular tachycardia may have a pulse (or might not!) whereas a person in ventricular fibrillation never has a pulse. A monitor is needed to identify the heart rhythmn. ...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?

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?

No. : No it's not normal but you may have the rhythm wrong. V fib is a life threatening arrhythmia often associated with ischemia (poor blood flow to the heart) and requires emergent treatment. ...Read more

Can you get a person out of v-fib or v-tach using bare hands?

No: V-tach may very well revert to a healthier rhythm by itself, v-fib less likely. There's no "magic touch". I hope i haven't misunderstood your question; thanks for asking. ...Read more

How can you tell the difference between v-fib or v-tach and asystole or pea with no electrical equipment? Basically, shockable vs nonshockable.

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 more

How does atrial fibrillation with ventricular standstill differ from fine v-fib?

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?

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 more

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?

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 more

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?

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?

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 more

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.

How can you tell difference between someone having heart attack and someone having ventricular fibrillation? Give aspirin for v-fib too or no?

How can you tell difference between someone having heart attack and someone having ventricular fibrillation? Give aspirin for v-fib too or no?

Vfib: Patients with ventricular fibrillation usually become unconscious or dead very quickly. A heart attack patient could have Vfib but more often has pain and other symptoms and is not unconscious if perfusion is adequate. Vfib implies very poor to no perfusion. ...Read more
