Need a diagnosis.
It's impossible to guide you in this forum, since (1) we are limited to 400 characters in our reply, which is insufficient to engage in a back-and-forth dialogue, & (2) we need a diagnosis in order to properly advise you.
Your condition may be benign. It may be due to an arrhythmia or serious heart problem. It's impossible to know w/o taking history, exam, & possibly testing. Use HealthTap Prime.
