I have noticed for the past few weeks irregularities in my heart beat, I had a holter monitor on for 24h, below are the results.

frequent single ventricular ectopics 1051 or so total plus 69 runs of bigeminy/trigeminy up to 10 seconds duration. rare atrial ectopics 4 or so total. sinus rhythm 50 to 130 per minute with an average of 88.

I have an appointment in a few weeks with a cardiologist but was wondering if anyone could give me an idea of what the casue may be and if I should be concerned at all??? greatly appreciated
