I'm really puzzled right now. My EKG keeps coming back abnormal, but the cardiologist didnt mention any problems before. I've started having palpitations, and there's been a lot of stress in my life lately. I decided to get a second opinion from a different cardiologist, but I'm confused. My EKG shows an incomplete right bundle branch block and a left anterior fascicular block. What does that even mean? My blood work is fine, my blood pressure is always excellent, and I dont have high cholesterol. Can you help me understand this?
