Doctor insights on:
Nonsustained Ventricular Tachycardia
Yes: But more important is looking for the reason you may have non-sustained VT. This would require a detailed evaluation by your physician. ...Read more
Is an EP study worth the risks in someone with multiple episodes NSVT (Non-Sustained ventricular tachycardia)? What can I gain from this??
Perhaps: If the problem is pathological RFA is possible. But at the moment, without a portable EKG monitoring to show it is significant I would wait. Nonetheless, your own cardiologist is the best advocate, Ask. ...Read more
I've had multiple long runs of monomorphic Non-Sustained Ventricular tachycardia. Echo & stress test normal. What causes this?
Many possible causes: certainly structural heart disease such as coronary disease or heart muscle disease can cause ventricular tachycardia and in the absence of this electrolyte abnormalities such high or low potassium or magnesium or other conditions such as right ventricular outflow tract navy or brugada syndrome or long QT syndrome or other genetic conditions can cause ventricular tachycardia ...Read moreSee 1 more doctor answer
Normal stress test, normal CTA w/calcium score, normal echo. I had 2 runs of non sustained ventricular tachycardia. What can cause this? I am Only 20
How can I be tested for Brugada syndrome? ECG has no indication but I've had a few runs of non sustained, monomorphic ventricular tachycardia.
Stress testing: testing for Brugada requires an EKG to look for the Brugada pattern. If present then Electrophysiologic testing is done to see if the pattern can be induced. It is genetic. Is there a history of sudden cardiac death in your family? Talk to your primary care provider about it. ...Read more
No specific signs: You can not determine if an abnormal heart rhythm is due to VT by how it feels. Vt is, by definition, a fast heart beat so people may feel pounding in their chest. Depending on the rate, they may become dizzy, short of breath, have chest pain, get sweaty and/or pass out. None of these symptoms are specific for vt. The rhythm must be recorded on ekg or on a monitor for definitive diagnosis. ...Read more
Life threatening: Ventricular tachcardia is a life threatening arrythmia. Its the rythm that needs to be "shocked". The pts in persistent v-tach is when shocking or medicine doesnt restore normal sinus rythm. The pt usually expire. ...Read more
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
Yes : Yes but only when the tachycardia is fast and not tolerated . But the electric current has to be synchronized with the heart beat.This is most appropriately called cardioversion than defibrillation the latter being unsynchronized electric shock for ventricular fibrillation which is a chaotic ineffective rhythm. ...Read more
You canpi if If not: treated probably you can not do high intensity training. See a cardiologist . I hope this helps. If you want to discuss my answer to your question or if you have more questions contact me on my Virtual Practice at www.healthtap.com/dryetimyan ...Read more
Usually low risk: Mitral valve redundancy, usually called prolapse, usually produces no symptoms or minor symptoms. If the valve leak is trivial, that's very good news and serious complications including ventricular tachycardia are not expected because the left ventricle is not under strain.. ...Read more
It depends: Some types of ventricular tachycardia can be modified or even eliminated with a procedure called an electrophysiologic study. Other types may be more complex and warrant long term medication or an implanted cardioverter-defibrillator. You should have yourself checked by a cardiologist that specializes in arrhythmias (an electrophysiologist) as soon as possible. ...Read moreSee 1 more doctor answer
See below: Normal heart rhythm arises in specialized cells within the right atrium called the sinus node and then is propagated over specialized conducting tissue into both ventricles. When an irritable focus in a ventricle begins firing independently repeatedly or in a repetitive loop, initiating it's own renegade rhythm at a rapid rate, it's called ventricular (where it starts) tachycardia (rate >100). ...Read moreSee 1 more doctor answer
Mechanism below:: When VT occurs at a fast enough rate, there is inadequate time for blood to fill the ventricle during each cycle, cardiac output falls, and blood pressure falls. Rate is the key variable. As tissue perfusion fails, acidosis, hypoxemia (low oxygen) and hyperkalemia (high potassium) result which leads to further deterioration in rhythm, ie, ventricular fibrillation and death. ...Read moreSee 1 more doctor answer
Yes: Black-outs (or syncope) are often caused by transient reductions in blood flow to the brain from a variety of causes. With ventricular tachycardia, the abnormal rhythm may be associated with a reduction in cardiac output and a temporary reduction in brain blood flow that can lead to syncope. ...Read moreSee 1 more doctor answer
