Heat and fluid loss can increase your heart rate. Resting in a cool place and staying hydrated, following your individual medical advice, may help.
However, we do not consider every tachycardia in the heat to be innocent. If it persists, recurs, or is unusual for you, it needs evaluation.
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.
The information is general and is not a substitute for medical evaluation. Do not change your treatment without instructions. For urgent symptoms call 112 or 166.
