Yes and No
The ticklish part is determining "normal" as that depends on the sophistication of the tests.
Pvcs resulting in loss of consciousness are not benign. Pvcs causing just palpitations with a normal echo
, ekg, and no evidence of coronary disease or other significant structural abnormality are benign. General rule: the health of the heart
, not the # of pvcs determines benignity. Family hx counts too.
