Hi Maria,
In situation likes this, we usually start with a history and physical exam to help risk statify the situation. An
echocardiogram, 12
leadLead poisoning EKGAtrioventricular block, ekg tracing
Ecg
Exercise stress test and a
holterHolter monitor (24h) monitor help us determine if heart function is
normalNormal saline flush, the frequency of the events and if they correlate with symptoms, and if we are lucky enough to see them on a 12-lead EKG, help localize the PVC.
If we can determine that you have 'normal heart' pvcs, we can try medications to decrease the symptoms (beta blockers and other antiarrythmic medications). If this doesn't help, the next consideration is ablation in very symptomatic people. If you have normal heart PVCs and are having sometmes several per minute, ablation of the most common variety (outflow tract PVCs) is usually possible.
Normal heart VTs carry a very low risk. The decision to move to more invasive therapies is based on symptoms. If you have normal heart VT, you should not worry.
I hope this answers your questions. Thanks for posting.
