Arrhythmias are heart rhythm disturbances: the heart can beat fast, slow or irregular. Their meaning varies according to type and background.
Some are benign, while others are related to heart disease, medications, or electrolyte disturbances and require treatment.
Recurrent fluttering, dizziness, or weakness needs evaluation. Note when they appear and how long they last.
For new, severe or persistent chest pain, sudden severe shortness of breath or fainting, call 112 or 166. Do not wait for a scheduled appointment.
