hello thanks for posting here. By PVC i assume you are speaking about premature ventricular contractions. so PVCs are present in a small percentage of normal people who may not have symptoms. they are usually an incidental finding. PVCs can be life threatening but only when they occur in groups or continuously where patient may experience symptoms like dizziness, loss of consciousness etc. Otherwise single occasional PVCs require no treatment. on what blood work came normal i cant comment but probably looks like your cardiac enzymes had been sent which came out normal. thank you
