What lifestyle modifications should I advise to patients with recurrent episodes of narrow complex tachycardia?

Advise patients experiencing recurrent episodes of narrow complex tachycardia to adopt the following lifestyle modifications:

• Weight loss and regular exercise if they are overweight or obese, as this can reduce arrhythmia burden and improve cardiovascular health.
• Smoking cessation to decrease cardiovascular risk and potential arrhythmia triggers.
• Limit alcohol consumption, since alcohol can precipitate episodes of tachycardia.
• Manage and reduce caffeine intake if it is identified as a trigger for episodes.
• Address and control any underlying cardiovascular risk factors such as hypertension or thyroid disease, which may contribute to arrhythmia occurrence.
• Provide education and support about symptom recognition, when to seek urgent medical review, and sources of patient information and support networks.
• Advise on driving and occupational safety according to the severity and frequency of symptoms, following DVLA guidance.

These lifestyle measures should be part of a personalised care package and combined with appropriate medical management and specialist referral if symptoms are uncontrolled or recurrent.
