How does my dr know by my holter monitor results that pacs are benign? had normal echo stress

PAC's: In otherwise healthy individuals without structural heart disease PAC's are almost always benign. It is a common cardiac dysrhythmia and generally not considered an abnormal finding. Symptoms such as sensation of skipped heart beat can be treated with beta blockers. Life style changes such as avoiding caffeine and tobacco and minimizing anxiety tends to help.

PAC: Hi, if no specific cause has been found (including ischemia or valvular heart disease) then PACs and PVCS are often termed “benign" and that usually indicates a very low likelihood that the arrhythmia is associated with any other significant cardiac disease, or that it is likely to lead to any other significant cardiac condition such as a heart attack.
