What Are Some Signs Of Ventricular Tachycardia
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.
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).See 1 more doctor answer
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.
VT, long QT: As usual this is far too complcated for the space here. You need an etiologic diagnosis for the arrhythmia and an estimate of the type of long QT syndrome present. There are several genotypes of long QT. Once this is done, there are drugs, electrophysiologic testing/therapy and device therapy all possible as well as anatomic or physiologic therapy depending on what is thought to be the cause
Depends: Ventricular tachycardia in the presence of structural hear disease is at risk of sudden death. However V Tach in a normal heart or without underlying heart disease is benign. It can cause palpitation but the risk of death is low. It often originates in the right side of the heart and can be treated with medicine or cured by ablationSee 1 more doctor answer
Ventricular tachycar: You should be seen by a cardiologist for evaluation and treatment without delay if you legitimately have VT and near syncope or syncope.
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.See 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.See 1 more doctor answer
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.
No/That's a problem!: Ventricular tachycardia is one of the most life-threatening abnormal heart rhythms. It can be associated with angina, but I am sure many doctors here have been called urgently to a hospital patient's bedside with v-tach much to the inquisitive look of the patient as they are wheeled urgently to intensive care for more careful monitoring and treatment. So no, not generally, but it is serious.
Everything: Svt arises in the atria (the upper chambers) and VT arises in the ventricles (lower chambers). Svt often occurs in otherwise healthy hearts and is annoying but only rarely serious. Vt usually arises in diseased hearts, can be serious, and sometimes is life-threatening. Vt in the setting of a heart attack or acute coronary syndrome is very dangerous.
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.
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.See 1 more doctor answer
