My heart gets agitated
for short periods of time by cigarette smoke, or pollen, or allergens or vehicle exhaust.
If I consume too much potassium, sodium or calcium, or chocolate, or caffeine, or carbohydrates during the day, my heart beat will become erratic
for long periods of time, either too slow, or too fast, or too hard or too weak.
When my heart starts beating hard, it usually lasts for quite a while. I wish my heart would stop it's hard beating after just 10 beats.
I hope that you can find the cause of your heart beat irregularity and take corrective action.
Regards.......
