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

Can ventricular tachycardia cause blackout?

Can ventricular tachycardia cause blackout?

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 more

What test/s detect fibrillation and ventricular tachycardia ? What causes them? :/

What test/s detect fibrillation and ventricular tachycardia ? What causes them? :/

EKG typically or: If it happens intermittently, your doctor may prescribe an event monitor or holter monitor, which is a device that you wear at home and can detect cardiac arrhythmias. The most common cause is coronary artery disease. ...Read more

If someone had angina from a quick BP drop but stabilizes will it cause damage or cause ventricular tachycardia?

If someone had angina from a quick BP drop but stabilizes will it cause damage or cause ventricular tachycardia?

No permanent injury: If the angina was caused by the blood pressure drop (caused, for example, by a medication), and it resolved (and the heart rhythm was normal) when the blood pressure returned to norma, l it is unlikely it caused permanent damage. However, if the angina was the cause of the blood pressure drop, that would be more concerning. Either way, this needs to be carefully evaluated by a doc. ...Read more

Can anterior mitral leaflet redundancy with trivial regurgitation cause ventricular tachycardia?

Can anterior mitral leaflet redundancy with trivial regurgitation cause ventricular tachycardia?

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

Would a run on non-sustained ventricular tachycardia of 4 beats cause a compensatory pause after?

Would a run on non-sustained ventricular tachycardia of 4 beats cause a compensatory pause after?

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

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 more

Arterial blood gas results: PH- 7.431, pCO2- 40.1, HCO3- 26.1, BE- 1.7. Are these normal or elevated? Could this cause Ventricular tachycardia?

Arterial blood gas results: PH- 7.431, pCO2- 40.1, HCO3- 26.1, BE- 1.7. Are these normal or elevated? Could this cause Ventricular tachycardia?

Normal blood gas ABG: The result you've provided so far seem within the reference range for most blood gas machines - so, "average". One result you didn't list is the pO2, which is a measure of the oxygen content of arterial blood. A low pO2 can cause ventricular tachycardia (VT); however, I suspect the ABG was used as part of a wider panel of tests to help determine cause of VT. Talk to the doctor who ordered the test ...Read more

Does coronary artery disease directly cause ventricular tachycardia or is it after heart attacks and damage etc?

Does coronary artery disease directly cause ventricular tachycardia or is it after heart attacks and damage etc?

Both: Myocardial infarction (heart attack) and scarring of the heart can lead to arrhythmias. Also, if coronary artery disease (CAD) causes impairment in flow of blood, ischemia may lead to arrhythmias. However, not all arrhythmias are due to CAD or mi. ...Read more
