Hi, summer seems to have diminished the number of people posting on and answering questions on this forum and elsewhere. Not being very familiar with RVOT VT, I did some research and was encouraged by what I found. Be sure to keep seeing your doctor and following his or her advice, but apparently RVOT VT is most often a benign condition. The excerpted text mentions avoiding stimulants such as coffee, but drugs, legal, illicit, or over-the-counter, must be carefully selected as to minimizing their potential to exacerbate your condition, for instance, many cold and diet medications are known to worsen arrhythmias.
The following information is linked and has been edited here to address your specific concern. Please visit the linked web site for full details.
"There are several subsets of patients without any structural heart abnormalities that have Ventricular Tachycardia. These forms of Ventricular Tachycardia fall into several categories, one of these being Right ventricular outflow tract tachycardia.
Of the outflow tract tachycardias, the right ventricular outflow tract tachycardias (RVOT) are the most common. These tachycardias have a typical characteristic ECG appearance.
RVOT tachycardias are generally considered benign. They may result in recurrent symptoms of palpitations and dizziness and less commonly loss of consciousness. There are limited data suggesting that a small subset of patients with RVOT tachycardias that are extremely rapid or result in loss of consciousness may have a greater risk associated with them but these data are inconclusive. Overall, the RVOT tachycardias are not considered life-threatening.
The RVOT tachycardias are commonly triggered by sympathetic stimulation such as anxiety and excitement. In additional stimulants such as caffeine seem to have a provocative role.
The treatment of RVOT tachycardias begins with reassurance since understanding that although this is a form of ventricular tachycardia, the condition is felt to be benign. The next step is avoidance of any stimulants such as caffeine that may be exacerbating the arrhythmias. Pharmacologic therapy usually starts with beta-blocker therapy. Beta-blocker therapy is usually more effective than calcium channel blocker therapy. If the patient remains particularly symptomatic despite pharmacologic therapy, one may consider catheter ablation of the RVOT tachycardia. Patients with frequent PVCs (for example 5-10%) provide an excellent endpoint in addition to the inability to produce the PVCs with isoproterenol, an adrenaline like substance. This therapeutic approach is the same for patients with highly symptomatic PVCs without ventricular tachycardia if the PVCs are localized to the RVOT. stanfordhospital.org/cardiovascularhealth/arrhythmia/conditions/ventricular-arrhythmias/vt.html
