I am 56, feel dizzy and nauseous and my bpm is 54. could this indicate a problem. I started using Nicotine patches on Monday, could these be the cause? I would class myself as overweight and unfit, I am also being treated for depression/anxiety, osteo-arthritus and a hiatus hernia also I am prescibed painkillers for lower back pain. Could I have something major wrong with my heart????.
