I have had paroxysmal palpitations which has interfered with my day to to day life. ECGs and holter show a notched (m shaped) r wave, frequent ventricular ectopies, and once one instance of 2nd degree AV block. No structural problems other than MVP , slight MR and TR. Had been taking ciplar 10 on doc s advice and felt great reduction in symptoms including fatigue , light headedness and occasional syncope . have stopped Ciplar now due to pregnancy (6 weeks) after consulting cardiologist . But Now the symptoms have come back with a vengeance, I have not been advised any rest so far by both gyno and cardio, but just cannot manage work (asst professor of zoology) especially exam invigilation when i have to stand for long and run around giving answer sheets, continuous lectures etc. Will my arrhythmia harm my baby?....how long can i keep suffering the symptoms before going back to my cardiologist?
