What causes sudden faster heartbeat and pounding head?
Patient: For the past couple of days, I have been having problems where my heart will randomly start pounding super fast, it s pounding so hard it hurts my chest, then everyone in a while my head will start pounding also. I just wondered if there was any suggestions on why this could be happening. Doctor: Thanks for your question on HCM.In my opinion you should get done few investigations to rule out cardiac cause.As poundinhead with fast heartbeat can be seen in1. Arrhythmia2. Valvular heart disease.So better to get fone ECG and 2D Echo first.If both are normal than go for Holter monitoring.  In this 24 hour recording of your ECG is done. Any arrhythmia can be picked up by this.If this is also normal than we need to rule out anaemia and thyroid problem. So get done CBC to rule out anaemia and S.TSH to rule out thyroid disease.
