Possible causes

Benign arrhythmias are heartbeat irregularities that do not cause any symptoms. Causes include certain medications, caffeine, nicotine, alcohol, cocaine, inhaled aerosols, diet pills, stress, etc.

  • Adjustment disorder

    A psychological disorder, often with low mood and anxiety. It is triggered by a sudden change in life circumstances, e.g. divorce or losing a job.
