They can also order blood tests to determine the levels of electrolytes and thyroid hormones. Diagnosis PVCs are caused by electrical impulses which misfire through the SA node, which is a structure found in the lower chambers of the heart. This causes the next heartbeat to be delayed, leading to a feeling like fluttering or skipped beats. PVCs can be seen in one pattern or repeated patterns. Doublets are PVCs that occur in a series of.
