Treatment For Ventricular Tachycardia
My father 70yr , diagnosed ventricular bigeminy.Is it dangerous?Can amiodarone help controlling it?Treatment options for ventricular tachycardia?
Depends: The underlying cause for the rythm needs to be worked up and treated. If all correctable conditions are fixed., then eps may be indicated and ablation if reasonable. A defibrillator if poor heart function. Otherwise amio is reasonable but has its issues. It can affect the lungs, liver and thyroid to mention a few. Close monitoring is reccomended. ...Read more
Yea: There is VT foci cardiac ablation, there is scar mapping- if VT is related to scar, there is mapping using pacing- if the VT causes your blood pressure to drop, there are a hand- full of anti arrhythmic medications that can be used and, of course, there is the implantable cardioverter defibrillator. Request to speak with a cardiac electrophysiologist about your options. ...Read more
What is the life expectancy for people with ventricular tachycardia? How serious is ventricular tachycardia, and what kind of treatment is available?
Variable: Vt has a wide spectrum of severity. Some kinds cause no symptoms and are benign and others deteriorate rapidly to ventricular fibrillation and cause death. In the setting of hypertrophic cardiomyopathy (your other question), VT is more serious and may require placement of an icd. Icds have been shown to greatly improve prognosis. ...Read moreSee 1 more doctor answer
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
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 ...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
