Concepts of modern technologies of diagnostics of the heart.

Electrophysiology

Electrophysiology

An electrophysiology evaluation can determine the cause of symptoms such as light-headedness, a slow or racing heartbeat, or shortness of breath. These can all be symptoms of a heart arrhythmia, a condition where the electrical impulses in your heart cause it to beat too fast, too slow or irregularly. Patients with certain kinds of arrhythmia are at an increased risk for blood clots and stroke.

If your heart arrhythmia symptoms are frequent and cannot be controlled with medication, you may need an electrophysiology procedure, such as ablation or an implanted device, to better control your arrhythmia. 

The electrophysiologists at the New England Heart & Vascular Institute are leaders in their field, performing a high volume of procedures each year and introducing new treatments to patients in the region. Our team was the first in New England to implant the WATCHMANTM device after FDA approval and the first to offer the 3-D Rhythmia Mapping System to better diagnose and treat all types of heart arrhythmias. 

The team at the New England Heart & Vascular Institute is here to provide you with ongoing care and support.

Diagnosis, Treatment and Technologies

Electrophysiology services at The New England Heart & Vascular Institute offers several options to help manage arrhythmias:

Arrhythmia diagnosis and risk assessment

If you have symptoms of an arrhythmia, you may be referred for outpatient testing in Non-Invasive Cardiology. This includes electrocardiograms, echocardiograms, Holter monitoring, event recorder, and exercise test (stress test or treadmill test). 
 
In certain cases you may have an event monitor implanted under the skin to keep track of the heart for long periods of time and automatically transmit data to the physician’s office. You could also be referred for a diagnostic cardiac electrophysiology study. This is when catheters are placed in the heart to record electrical signals inside the heart.

Radiofrequency ablation to control arrhythmias

Some arrhythmias are caused by abnormal cells and circuits in the heart tissue that alter the conduction of the electrical signals which control the heartbeat. Ablation can improve heart arrhythmias by destroying those abnormal cells and circuits that can cause an irregular heartbeat. 

During the procedure, catheters are placed in the heart. Radiofrequency energy is delivered through one of the catheters and ablates the cells and circuits responsible for the arrhythmia.

Defibrillator (ICD), pacemaker, or biventricular pacemaker (CRT)

Implantable cardioverter defibrillators (ICDs) and pacemakers are devices that can help maintain a normal heart rhythm. A pacemaker uses electrical pulses to help the heart beat normally when it is too slow. An ICD senses a dangerously abnormal rhythm and delivers therapy to stop the dangerous rhythm. ICDs also act as pacemakers. A biventricular ICD or pacemaker, known as a CRT (Cardiac Resynchronization Therapy) device, is for heart failure patients who may have an arrhythmia. This device helps the chambers of the heart to beat in a way that relieves symptoms of heart failure.

These devices are generally placed under the skin near the shoulder and have wire leads placed into the heart.  The New England Heart & Vascular Institute now offers Micra the world’s smallest, leadless pacemaker.  The device is inserted directly into the heart via a catheter and is about the size of an adult vitamin. 

Follow-up of implanted devices

After receiving an implanted device, your provider will continue to monitor your care. It is important to check the battery and the leads on a regular basis to make sure the device is working properly. Using advanced technology, this can be done from home, eliminating the need of an office visit.
