Arrhythmia Evaluation and Treatment

Arrhythmia evaluation and treatment — diagnosis of cardiac rhythm disorders and a personalized treatment plan.

Comprehensive program in which heart rhythm is assessed using ECG and long-term monitoring in patients presenting with palpitations, fainting, or irregular pulse.

Indication

  • Palpitations or sensation of irregular heartbeat
  • Dizziness, fainting (syncope), or pre-syncope symptoms
  • Atrial fibrillation (AF) or atrial flutter
  • Supraventricular tachycardia (SVT) and ventricular arrhythmias
  • Bradyarrhythmias (slow heart rate), AV block
  • Screening for occult AF in patients with a history of stroke or transient ischemic attack
  • Suspicion of inherited arrhythmia syndromes (long QT, Brugada, etc.)

Preparation

  • Recording the onset, frequency, duration, and triggers of symptoms
  • List of all medications and supplements being used
  • Previous ECG, Holter, and ECHO recordings
  • Blood tests for thyroid function, electrolytes, and complete blood count

How it's performed

  1. Detailed examination and review of symptoms
  2. Baseline rhythm assessment with a 12-lead ECG
  3. Continuous rhythm monitoring: 24-72 hour Holter, event recorder, or implantable loop recorder
  4. Echocardiography to screen for structural heart disease
  5. Exercise stress test for exercise-induced arrhythmias; electrophysiology study if needed
  6. Stroke and bleeding risk are calculated using CHA2DS2-VASc and HAS-BLED scores in atrial fibrillation
  7. Treatment plan: lifestyle measures, antiarrhythmic medications, anticoagulation with DOACs when indicated, catheter ablation, or permanent pacemaker

Post-procedure

  • Early follow-up (2-4 weeks) for patients started on antiarrhythmic or anticoagulant therapy
  • ECG every 3-6 months in stable patients, with Holter monitoring as needed
  • Monitoring for bleeding signs and renal function in patients on DOACs or warfarin
  • Three-month 'recovery period' followed by rhythm follow-up after catheter ablation
  • Device checks (remote or in person) for patients with pacemakers or ICDs

Risks

  • Proarrhythmic effects (new rhythm disturbance) of antiarrhythmic medications
  • Bleeding risk associated with anticoagulant use
  • Vascular injury, cardiac tamponade, or stroke during catheter ablation (rare)
  • Infection or lead complications during pacemaker/ICD procedures
  • Risk of stroke, heart failure, or sudden cardiac death in untreated arrhythmias

FAQ

Are palpitations always dangerous?

No. Most palpitations are benign, but they should be evaluated based on duration, accompanying symptoms, and the presence of underlying heart disease.

Why do I need blood thinners if I have atrial fibrillation?

AF can lead to clot formation in the atrium and cause stroke. If the CHA2DS2-VASc score is appropriate, direct oral anticoagulants (DOACs) significantly reduce the risk of stroke.

Is ablation a surgery?

No. Ablation is an interventional procedure in which the heart is reached via the blood vessels and the area causing the arrhythmia is neutralized with a catheter.

Do caffeine and alcohol trigger arrhythmias?

Excessive caffeine, alcohol, sleep disturbances, and stress can trigger arrhythmias in some individuals; reducing triggers is an important step in treatment.
