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

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

What is arrhythmogenic right ventricular cardiomyopathy?

What is arrhythmogenic right ventricular cardiomyopathy?

ARVC: Arvc is a cardiomyopathy that results in partial or total replacement of right ventricular muscle by fat or fibrous tissue. The principal problem is life-threatening heart rhythm disturbances which are the cause of death in these patients. Medications can suppress the arrhythmias but sometimes an aicd is needed. There is a genetic form of arvc. Cardiac MRI is useful for diagnosis. ...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

Abnormal ECG sinus bradycardia and septal infarct age undetermined?

Abnormal ECG sinus bradycardia and septal infarct age undetermined?

Depends: Sinus bradycardia can be normal in a fit individual. Septal infarct age undetermined may also be a normal variant, but also possibly indicate previous injury to the heart. You might want to consider getting further evaluation, such as a stress treadmill ECG test. Depending on various associated healthy issues, this might need to be combined with imaging (nuclear or ultrasonography). ...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

Could ventricular septal defect cause diastolic murmur?

Could ventricular septal defect cause diastolic murmur?

Two ways: A large vsd with increased pulmonary blood flow may cause a diastolic flow rumble caused by a large amount of flow coming back from the lungs across the mitral valve into the left ventricle. Perimembranous and supracristal vsds can cause aortic valve deformation, and subsequent development of a diastolic murmur of aortic valve insufficiency. ...Read more

Is intraventricular conduction delay ECG serious?

Is intraventricular conduction delay ECG serious?

Sometimes: Intraventricular conduction delay (ivcd) refers to a condition in which electrical conduction through the heart muscle is delayed or slowed. It can be seen in a variety of disorders such as myocarditis, cardiomyopathy, ventricular fibrosis, heart failure, a high potassium level, and following a heart attack. Mild ivcd can be seen in normal healthy people as well. Check with your doctor. ...Read more

What causes atrial arrhythmias?

What causes atrial arrhythmias?

Many causes: First off, need an ultrasound (echo) of your heart, because structural abnormalites of the heart are the first big cause that needs to be eliminated. If your heart is structurally normal, then the other big cause for atrial arrhythmias is diet and drugs -- especially any caffeine or diet pills. Finally, sometimes it is just idiopathic -- which means we cannot find a cause. ...Read more

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

Bradycardia and rbbb, history heart defect?

Bradycardia and rbbb, history heart defect?

Get seen: Some folks are born with problems with the av node and its branches ("right bundle branch block", etc.), or a tiny heart attack or a bit of amyloid or a few other things can cause troubles here as well. A cardiologist visit's probably in order, and you may end up chatting about whether you want an electronic pacemaker. ...Read more

Would paroxysmal atrial fibrillation cause mental impairment?

Would paroxysmal atrial fibrillation cause mental impairment?

Yes: Paroxysmal atrial fibrillation (afib) refers to a brief episode of irregular heart rhythm that may cause a variety of symptoms including confusion, palpitations, sweating, chest pain, nausea, vomiting, and sometime even stroke symptoms including changes in language, facial drooping, weakness, and numbness to name a few symptoms. It is important to be seen by a doctor to have a complete exam. ...Read more

Is supraventricular tachycardia deadly?

Not usually: Svt should no be deadly. If it lasts for a long time(many hours or days), the heart can get tired and that is potentially dangerous. ...Read more

What is supraventricular extrasystole?

What is supraventricular extrasystole?

Supraventricular: It is an extra heart beat which was initiated above the ventricles. That is usually an atrial premature beat but could be an AV junctional premature beat. Both are distinct from Ventricular premature beats. ...Read more
