While awaiting appointment to see specialist regarding heart arrhythmia diagnosis. is there anything i can do to decrease my risk for sudden death ?

Heart Arrythmia: Perhaps your primary care physician could do basic work up including ekg, 24 or 48 hour holter monitor, or 30 day event monitor and echo. Do not drink caffeinated drinks (could cause or worsen svts). Avoid stressors.

Depends: Some arrythmias are benign. If it involves ventricular side, have structural heart problem......Risk is more. So avoid stimulants....Caffine, nicotine, otc decongestant medications, strainuous exercise, competitive physical activity.Medications...... Mental health, some antibiotics, some anti-arrythmic meds themselves, watch for electrolytes, fluid pill.........Etc.
