Management of Caffeine-Induced Palpitations

Immediate Management Steps

The American Heart Association recommends immediately eliminating all caffeine intake, including coffee, matcha, energy drinks, and caffeine-containing medications or supplements, as caffeine cessation alone is often sufficient to control palpitations in patients with anxiety and a negative cardiac workup 1, 2, 3, 4
The American College of Cardiology suggests that caffeine is a well-established trigger for tachyarrhythmias, particularly in young adults and those with anxiety disorders, and energy drinks are particularly problematic as they contain high caffeine loads plus other cardiac stimulants 1, 3
Patients with panic disorder, 45% of whom have mitral valve prolapse, experience significantly greater increases in anxiety, nervousness, fear, palpitations, and tremors compared to healthy subjects when consuming caffeine 1

The American College of Cardiology recommends obtaining a 12-lead ECG to capture the arrhythmia during symptoms if palpitations are still present, and looking specifically for pre-excitation (delta waves) on the resting ECG, as this indicates Wolff-Parkinson-White syndrome and requires immediate electrophysiology referral due to risk of sudden death 2, 3, 4, 5
The American Heart Association suggests using a 24-hour Holter monitor if palpitations occur daily or several times per week, and using an event recorder or wearable loop recorder if episodes are less frequent (less than daily) 1, 2, 3, 4, 5

The American College of Cardiology recommends that if symptoms resolve, no further cardiac workup is needed beyond what has already been completed, and addressing underlying anxiety disorder is essential, as depression, poor self-rated health, and anxiety are significant predictors of palpitations 1, 4
If symptoms persist despite caffeine elimination, the American Heart Association suggests teaching vagal maneuvers (Valsalva, carotid massage) to help terminate episodes and confirm re-entrant tachycardia involving AV nodal tissue, and considering empiric beta-blocker therapy if significant bradycardia (<50 bpm) has been excluded 1, 3, 4

The American College of Cardiology recommends referring immediately to cardiac electrophysiology if pre-excitation is present on ECG (WPW syndrome), severe symptoms occur during palpitations (syncope, dyspnea, chest pain), wide complex tachycardia of unknown origin is documented, symptoms persist despite caffeine elimination and beta-blocker therapy, or patient desires definitive therapy (catheter ablation) rather than chronic medication 2, 3, 4, 5
