Management of Palpitations

Immediate Assessment and Risk Stratification

The American College of Cardiology recommends that patients presenting with palpitations require immediate evaluation for hemodynamic instability and high-risk features that determine the urgency and setting of management 1, 2
Patients with syncope or near-syncope during palpitations should be hospitalized for evaluation, monitoring, and management when ventricular arrhythmia is documented or suspected 1
Pre-excitation (delta waves) on resting ECG indicates Wolff-Parkinson-White syndrome and requires immediate electrophysiology referral due to sudden death risk, particularly if irregular palpitations suggest atrial fibrillation 3
Wide complex tachycardia of unknown origin mandates immediate specialist referral 3
Sustained ventricular arrhythmias require hospitalization for initiation of antiarrhythmic therapy 1, 5
Associated chest pain, dyspnea, or severe symptoms warrant urgent evaluation for structural heart disease 1, 4, 5

The American Heart Association recommends obtaining 12-lead ECG immediately, as this is the gold standard initial test and may capture the arrhythmia if symptoms are present 3, 5
Assessing for structural heart disease with echocardiography is particularly important in patients with sustained palpitations or concerning symptoms 3, 5
Reviewing medications and triggers, such as caffeine, alcohol, nicotine, and stimulant medications, is essential to identify potential causes of palpitations 1, 2, 4

The American College of Cardiology recommends eliminating precipitating factors first, and caffeine cessation alone is often sufficient to control palpitations in patients with anxiety and negative cardiac workup 4
Removing all caffeine sources, including coffee, matcha, energy drinks, and caffeine-containing medications or supplements, is recommended 4
Addressing anxiety disorders, such as depression, poor self-rated health, and anxiety, is significant in predicting palpitations 4
Teaching vagal maneuvers, such as Valsalva and carotid massage, can help terminate episodes and confirm re-entrant tachycardia 3, 4
Initiating beta-blocker therapy is recommended if symptoms persist after trigger elimination, particularly when associated with mild tachyarrhythmias or increased adrenergic symptoms (Class I recommendation) 2
Ensuring significant bradycardia (<50 bpm) has been excluded before starting beta-blockers is crucial 3, 4
Non-dihydropyridine calcium channel blockers, such as verapamil and diltiazem, are effective alternatives for patients who cannot tolerate beta-blockers (Class IIa recommendation) 2
Adenosine is the drug of choice for terminating AV nodal re-entrant tachycardia (Class I recommendation) 2

The American Heart Association recommends referring immediately for pre-excitation on ECG (Wolff-Parkinson-White syndrome) 3, 4
Syncope or severe symptoms during palpitations require immediate referral 1, 4, 5
Wide complex tachycardia of unknown origin mandates immediate specialist referral 3, 4
Evidence of structural heart disease requires referral 5
Documented complex or sustained ventricular arrhythmias require hospitalization for initiation of antiarrhythmic therapy 1, 5
Symptoms persisting despite caffeine elimination and beta-blocker therapy require referral 4
Patient desires definitive therapy (catheter ablation) rather than chronic medication 6, 4
Drug resistance or intolerance in patients with documented arrhythmias requires referral 3

Never rely on automatic ECG interpretation systems, as they are unreliable and commonly suggest incorrect arrhythmia diagnoses 3
Do not delay obtaining 12-lead ECG during tachycardia, and encourage patients to seek immediate evaluation during episodes to capture the arrhythmia 3
Avoid empiric antiarrhythmic therapy without documented arrhythmia, as Class I and III agents carry significant proarrhythmia risk 3
Do not assume benign etiology in patients with irregular palpitations and pre-excitation, as this suggests atrial fibrillation in WPW syndrome, which carries sudden death risk 3
Recognize that palpitations frequently occur during normal rhythm, and symptom-rhythm correlation through ambulatory monitoring is essential 1
