What causes skipping of heartbeat, chest tightness and lightheadedness?
Patient: hi doctor,i have skip beat i guess.sometimes it happens for many days before going away.when i m having it,symptoms like very mild tightness in chest,lightheadedness and fatigue will follow.there would be uncomfortable feeling in chest.i m worried can it cause sudden heart attack?thanks Doctor: Welcome to HCM: Please note that this sounds like Atrial Fibrillation, and it can cause a stroke. Please go and see a doctor and get an EKG and get evaluated. Of course it can lead to a heart attack, but a stroke is major concern. I hope this helps, good luck
