Hi doctors, can frequent atrial ectopics ( 12063 beats, holter moniter ) cause problems ? angiogram 3 years ago all clear. thankyou.

Yes, it's a problem: Assuming you have a normal heart rate, your APCs are >10% of your total heart beats. That can cause your heart muscle to weaken and increases your risk of atrial fibrillation. You need a full evaluation for any treatable cause and your heart rate should be assessed to be sure it's well controlled to avoid injury. Is your sleep apnea treated? CPAP may help your arrhythmia if you haven't tried it.
