Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Not usually: Not typically; however, if you also have an accessory pathway (wolff-parkinson-white syndrome), this is a unique situation where af is known to cause very rapid ventricular activation during af, which can lead to vf. Rapid ventricular response may cause cardiac weakening over time, which in turn may increase the risk of vf. ...Read more

Ventricular fibrillation fatal?

Ventricular fibrillation fatal?

Possibly..: In ventricular fibrillation, vfib, the heart is quivering and there is no blood flow so the person is clinically dead. If the heart cannot be restored to a rhythmn where there is blood flow, the patient will then be pronounced dead. Treatment for this rhythmn includes electrically shocking the heart as quickly as possible. Performing CPR in the meantime can be life-saving. ...Read more

Heart problems ventricular bigeminy?

Heart problems ventricular bigeminy?

Usually benign: Premature or "skipped" beats frome the bottom chambers of the heart are common; they sometimes occur in fixed patterns. When every other beat is a premature beat, it's called ventricular bigeminy. When every 3rd beat is premature, it's called ventricular trigeminy, and so on. Bottom line: with a normal heart, these patterns are completely benign and don't need treatment unless very troubling. ...Read more

Compare ventricular vs supraventricular tachycardia?

Compare ventricular vs supraventricular tachycardia?

Atria or ventricles: Supra ventricular tachycardia: from upper chambers of the heart, is due to irritability (increased automaticity) or a short circuit (reentry), heart is usually structurally normal. Ventricular tachycardia: from lower chambers of the heart, due to irritability, can occur in normal hearts but is more often seen in hearts with scar tissue or weak hearts and can be life threatening. ...Read more

Ventricular tachycardia managment?

Ventricular tachycardia managment?

Ep: This is a serious condition and you must see an electrophysiologist. If normal heart, it is possible at your age to manage with medication but often can have an ablation and cure it. ...Read more

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

Only in a Very Few: Generally, the answer to this is a very solid "no." this is a rare complication of people with another condition (on top of their afib) called wolff-parkinson-white syndrome (or wpw). In certain patients having both conditions, the top chamber is too-well connected to the bottom and can trigger ventricular fibrillation. ...Read more

Are premature atrial contractions dangerous?

Are premature atrial contractions dangerous?

No: There is far more concern with a completely disorganized atrial rhythm called atrial fibrillation. Occasional early beats are of no concern. ...Read more

Are premature atrial contractions dangerous?

Are premature atrial contractions dangerous?

In general no: In general pacs or premature atrial contractions are benign - not harmful. They may be caused by excessive stimulants such as caffeine, nicotine, even sugar. Anxiety can also cause this - if your physician has thoroughly evaluated this and ruled out other causes this may be the issue. ...Read more

Not enough info: What distinguishes the significance of a rhythm disturbance is what the condition of the heart is, not the rhythm per se. Your mother needs an evaluation which includes information about how strong her heart is and whether she has evidence of blocked arteries. Other considerations are what meds she takes, her use of nicotine, alcohol and caffeine, and what symptoms, if any, she has. Warm wishes. ...Read more

Why is ventricular fibrillation worse than atrial fibrillation?

Fibrillation: atrial fibrillation has normal left ventricular contractions put poor atrial function. Ventricular fibrillation has no real ventricular contractions so blood pumping essentially stops. Atrial fibrillation is a rhythm you can live with. Ventricular fibrillation is a rhythm you die with unless it is corrected quickly. ...Read more

Slow heart rate, premature atrial contractions, are they connected?

AV Block?: Yes, it is very possible that the slow rate of ventricular contractions cannot keep up with a faster atrial contraction rate. It is an a-v block. ...Read more

14 day loop results states tachycardia up to 140, bradycardia 42 bpm, ventricular ectopic complexes, supra ventricular ectopic complexes and an atrial couplet. Should I be worried?

14 day loop results states tachycardia up to 140, bradycardia 42 bpm, ventricular ectopic complexes, supra ventricular ectopic complexes and an atrial couplet. Should I be worried?

Arrhythmias: You should be talking to your doctor about the situation to get more information. The rhythms alone don't necessarily imply something 'bad'. On the other hand if you were entirely normal they wouldn't be there. The rest of your condition is what tells you whether you should be worried. Your doctor is best positioned to answer that question. ...Read more

Vtac/vfib vs asystole?

Vtac/vfib vs asystole?

Both critical: Asystole mean ther is no heart activity the heart is not beating or moving in any way, it is the rhythm that a patient has when they are pronounced dead. Vtac and vfib are potential reversibly life threatening rhythms where the heart still has activity but it is not synchronized to provide forward blood flow. When recognized immediately there are interventions to reverse these two rhythm. ...Read more

What causes pulseless ventricular tachycardia?

What causes pulseless ventricular tachycardia?

Not really pulseless: When VT occurs at a fast enough rate, there is inadequate time for ventricular filling, cardiac output falls, and blood pressure falls. You may not be able to palpate a pulse but an arterial line would show a waveform that is reduced in amplitude. Rate is the key. As tissue perfusion fails, acidosis, hypoxemia and hyperkalemia result leading to ventricular fibrillation and death. ...Read more
