Atrial Fibrillation / Arrhythmia

Atrial Fibrillation / Arrhythmia

Dr. Hamdan provides a broad range of treatment options for patients diagnosed with arrhythmia, from noninvasive interventions to device therapy to minimally invasive surgery.

Heart Arrhythmia & Atrial Fibrillation (AFib)

What is Heart Arrhythmia?

An arrhythmia is a heart rhythm abnormality that may indicate a serious problem and can lead to heart disease, stroke or even death. An arrhythmia may be suspected when a physician hears a fast or irregular heartbeat while listening to the heart with a stethoscope.

What is Atrial Fibrillation (AFib)?

Atrial fibrillation, or “AFib,” is the most common type of arrhythmia – it affects about 2.2 million Americans, with 160,000 new cases diagnosed annually.

Whether the condition is intermittent or chronic, patients with atrial fibrillation or “AFib” are at higher risk for blood clots and strokes.

Types of Heart Arrhythmia

Common types of heart arrhythmia include:

  • Atrial fibrillation (AFib)
  • Atrial flutter
  • Atrial tachycardia
  • Supraventricular tachycardia
  • Heart block
  • Sick Sinus Syndrome
  • Wolff-Parkinson-White Syndrome
  • Ectopic heartbeat
  • Premature ventricular contractions
  • Ventricular tachycardia
  • Ventricular fibrillation

Causes and Risk Factors of Heart Arrhythmia

Causes and risk factors of heart arrhythmia include:

  • Alcohol or drug abuse
  • Congestive heart failure
  • Coronary artery disease
  • High blood pressure (hypertension)
  • Hypertrophic cardiomyopathy
  • Medications and supplements
  • Obesity
  • Overactive thyroid gland (hyperthyroidism)
  • Pericarditis
  • Smoking
  • Valvular heart disease

Symptoms of Heart Arrhythmia

An arrhythmia can be “silent” and may not cause any symptoms, but among individuals who experience heart arrhythmia symptoms, common complaints include:

  • Chest pain
  • Fainting
  • Fast or slow heartbeat (palpitations)
  • Light-headedness, dizziness
  • Paleness
  • Shortness of breath
  • Skipping beats – changes in the pattern of the pulse
  • Sweating

Diagnosing Heart Arrhythmia and Atrial Fibrillation (AFib)

Tests to find underlying heart diseases may include:

  • Tests to find underlying heart diseases may include:
  • Angiography
  • Echocardiogram
  • Electrophysiologic study (EPS)
  • Stress test
  • Nuclear imaging tests

Heart Arrhythmia and Atrial Fibrillation Treatment

Dr. Hamdan provides a broad range of heart arrhythmia and atrial fibrillation treatment options, from noninvasive interventions to device therapy to minimally invasive surgery. These include:


Many medications are available to treat a fast or irregular heartbeat, also known as arrhythmia. Medications are given to prevent arrhythmias and slow the heart rate. In most cases, the drugs have to be taken for the rest of the patient’s life.

Minimally Invasive Surgery

  • Valvuloplasty
  • Minimally Invasive Valve Repair/Least Invasive Valve Surgery (LIV)
  • Percutaneous Aortic Valve Replacement
  • Mitral Valve Repair with Evalve®
  • Wolf Mini-Maze

Non-surgical Procedures

  • Heart ablation
  • Cardioversion

Device Therapy

  • Pacemaker
  • Internal cardioverter defibrillator (ICD)
