Hello! After going through your problem , I would like to suggest you that
1) It could really be indicative of a serious cardiac conduction defect like arrhythmias.
2) So, it would be better to have a consultation with an eminent cardiologist & investigated accordingly to search into the cause.
3) It could be attributable to a dysarrhythmia like SVT
4) It would be curable by RFCA (Radiofrequency catheter ablation
Thanks & take care of yourselves!
