I spent 26 hours in the hospital after having bad chest pain and other symptoms. I took a picture of the top of my ekg just because. It stated sinus tachycardia, moderate intraventricular conduction delay, minimal st depression and and abnormal rythm ecg. What does all of that.mean? I'm now prescribed double my usual dose of lisinopril, baby aspirin and micro-k and I have to carry nitro with me. I'm only 35. They did find that my potassium is really low and the ekg they did a while after giving me potassium was normal. I also got to see my heart skip beats on the ekg after the stress test. Nervous and no diagnosis.
