An arrhythmia is an abnormal rhythm of the heart which can cause it to beat too fast, too slow, or unevenly. Emerson, through its cardiology affiliation with Massachusetts General Hospital, offers the full spectrum of arrhythmia care.


Emerson Hospital cardiologists work closely with physicians from the the Mass General Cardiology Program at Emerson Hospital to treat patients with arrhythmias. Electrophysiologists — physicians who are experts in heart rhythm disturbances — evaluate patients in Concord and work with Emerson cardiologists to develop treatment plans. Patients benefit from the expertise of a world-renowned academic medical center in a convenient location. Available treatments at Emerson and Mass General include:

  • Anti-arrhythmic medications
  • Implantable cardioverter defibrillators (ICDs) and pacemaker insertion
  • Catheter ablation, including cryoablation and radiofrequency ablation
  • Cardiac resynchronization therapy (CRT)
  • Electrical cardioversion
  • Complicated ablation procedures and pulmonary vein isolations

Diagnosis and Testing

Cardiac arrhythmias are diagnosed using procedures such as electrophysiology studies. Emerson cardiologists and the affiliated cardiac specialists in the Mass General Cardiology Program at Emerson offer a range of diagnostic procedures for cardiac arrhythmias. Diagnostic tests include:

  • Electrocardiograms, including signal-averaged electrocardiography (EKG or ECG)
  • Holter monitoring
  • Event recorder
  • Echocardiogram
  • Exercise test (stress test or treadmill test)
  • Tilt table evaluation
  • Invasive electrophysiology studies


Emerson Hospital offers a comprehensive array of services for patients with heart problems including:

  • Coronary Care Unit where patients with serious heart problems are closely monitored and receive specialized, individual care.
  • Telemetry Unit designed for patients with heart-related problems who require monitoring, but need less intensive nursing care than is provided in the CCU.
  • The Mass General Cardiology Program at Emerson offers specialists in electrophysiology, women’s heart health, and advanced heart failure.
  • Cardiology Lab offering testing for heart disease, including electrocardiograms (EKGs), trans-esophageal echocardiography, holter monitoring, echocardiograms, stress testing and nuclear stress testing.
  • A Cardiac Rehabilitation Program designed for patients who have experienced a heart attack, coronary artery bypass grafting, angioplasty or valve replacement surgery or who suffer from angina.
  • Board-certified cardiologists with offices in Concord and Westford.
  • Pediatric cardiologist from Mass General with an office in Concord.
