Treatment for Sinus Tachycardia Due to Anxiety
Understanding the Clinical Context
- The American College of Cardiology, American Heart Association, and Heart Rhythm Society guidelines state that physiological sinus tachycardia from emotional stress is expected to resolve with correction of the underlying cause, which is addressing the anxiety disorder itself 1, 2, 3
- Sinus tachycardia triggered by anxiety is classified as physiological sinus tachycardia resulting from appropriate autonomic influences during emotional responses, differing from inappropriate sinus tachycardia (IST) where the elevated heart rate occurs without physiological justification 1, 2, 3, 4, 5
Treatment Algorithm
- The mainstay of management is identifying and treating the anxiety disorder, which may include referral to mental health services for anxiety management, cognitive behavioral therapy, and anxiolytic medications as appropriate for the anxiety disorder itself 3, 4, 6, 7
- Beta-blockers are the first-line pharmacologic option for symptomatic relief while addressing the underlying anxiety, working by blunting the sympathetic response that drives the tachycardia during anxiety episodes 7, 8
Important Clinical Caveats
- Beta-blockers should be used for symptomatic relief in patients with anxiety-induced sinus tachycardia who have distressing palpitations, and are particularly helpful when anxiety triggers are being addressed but symptom control is needed during treatment 7
- It is critical to distinguish anxiety-triggered physiological sinus tachycardia from IST, as treating true anxiety-induced sinus tachycardia as IST leads to overtreatment with medications that may be ineffective or poorly tolerated 1, 2, 4, 5
