Key Interview Questions for Palpitation Follow-Up

Focus your interview on characterizing the rhythm pattern (regular vs. irregular), temporal features (onset, duration, frequency, triggers), associated symptoms (syncope, chest pain, dyspnea), and identifying underlying cardiac disease or risk factors. 1

Essential History Components

Rhythm Characteristics

  • Regular vs. irregular palpitations: Irregular suggests premature beats, atrial fibrillation, or multifocal atrial tachycardia; regular with sudden onset/termination suggests AVNRT or AVRT 1
  • Pattern of onset and termination: Abrupt onset and termination (paroxysmal) points to re-entrant tachycardias; gradual acceleration suggests sinus tachycardia 1
  • Response to vagal maneuvers: Termination with Valsalva or carotid massage strongly suggests AV nodal-dependent tachycardia 1

Temporal Pattern

  • Number of episodes, frequency, and duration 1
  • Date of first episode and pattern over time 2
  • Specific triggers: Exercise, emotional stress, alcohol, caffeine, large meals, sleep, postural changes 3, 2
  • Time of day: Nighttime or post-meal episodes suggest vagally-mediated arrhythmias; daytime suggests adrenergic triggers 4

Associated Symptoms (Critical for Risk Stratification)

  • Syncope or presyncope: Occurs in ~15% of SVT patients, may indicate rapid rates, accessory pathway conduction, or structural disease 1, 3
  • Chest pain: Distinguish exertional vs. non-exertional; may indicate ischemia 3
  • Dyspnea, orthopnea, paroxysmal nocturnal dyspnea: Suggests heart failure or tachycardia-mediated cardiomyopathy 3
  • Polyuria: Release of atrial natriuretic peptide during sustained SVT 1
  • Lightheadedness, fatigue 1

Cardiac Disease and Risk Factors

  • Known structural heart disease: Coronary disease, valvular disease (especially mitral valve prolapse), cardiomyopathy, congenital heart disease 3, 2
  • Cardiovascular risk factors: Hypertension, diabetes, hyperlipidemia, smoking 3
  • Prior myocardial infarction 3

Medication History

  • Antiarrhythmic medications and response 3, 2
  • QT-prolonging medications (risk for torsades de pointes) 3
  • Stimulants: Cocaine, amphetamines, supplements, anabolic steroids 3
  • Over-the-counter medications 3

Family History (High-Yield for Risk Stratification)

  • Sudden cardiac death or aborted sudden death in first-degree relatives 3
  • Inherited arrhythmia syndromes: Long QT, Brugada, CPVT, short QT 3
  • Cardiomyopathies: Hypertrophic, dilated, ARVC 3
  • SIDS or unexplained drowning (may indicate channelopathy) 3
  • Congenital heart disease 3

Medical History

  • Thyroid disease (hyperthyroidism is a reversible cause) 3, 2
  • Kidney disease or electrolyte abnormalities 3
  • Pulmonary disease (associated with multifocal atrial tachycardia) 1
  • Alcohol use 3, 2
  • Prior stroke or embolic events 3
  • Misdiagnosed epilepsy (arrhythmic syncope can be mistaken for seizures) 3

Clinical Pitfalls

Age and sex matter: Women have twice the risk of PSVT and more commonly present with AVNRT; onset after age 50 suggests AVNRT over AVRT 5. In this 59-year-old woman, AVNRT is more likely than accessory pathway-mediated tachycardia.

Don't miss psychiatric overlap: 67% of patients with unrecognized SVT meet criteria for panic disorder; 54% have symptoms attributed to anxiety 5. However, establish organic causes first before attributing symptoms to psychiatric disease.

Asymptomatic periods are common: Patients with paroxysmal arrhythmias are often asymptomatic at evaluation 1. The absence of symptoms during your visit doesn't exclude significant arrhythmia.

What the ED found matters: Review ED records for documented rhythm, heart rate during episode, response to any interventions, and ECG findings 2.
