Hello all. I have been diagnosed with sinus bradycardia. With a heart rate sometime resting in 40s and 50s. This began in December with lightheadedness and pain. After having a stress test, Ecco and many ER visits they assure me it isn’t my heart. I am wearing an event monitor now because issues still don’t stop. Pains are al on my left side. Random. Anywhere from mild chest, leg, back and arm. And I have lightheaded spells or fogginess a lot lately. I’m really concerned but don’t know what to think or what’s next. Anyone have any advice on this?
