Aww, I haven't personally dealt with arrhythmia during pregnancy pero alam ko marami sa amin na may heart concerns, kaya naman important talaga na makipag-ugnayan ka sa OB mo about this para ma-monitor nang maigi. A few of us na may health issues sa pregnancy always say na ang maayos na communication with the doctor at regular checkups ang lifesaver, especially pag may something like this na kailangan ma-manage carefully. Sana makakita ka ng mommy dito na makakarelate sa experience mo, pero please don't delay telling your doctor kung hindi ka pa, they need to know para ma-adjust ang treatment plan if needed. Sending you strength, mommy!
