What does an electrophysiologist do?
An Electrophysiology (EP) Study is a recording of the electrical activity of your heart. This test is used to find the cause of the patient’s rhythm disturbance and determines the best treatment. During the test, Dr. Bedi may safely reproduce your arrhythmia, then give you medications to see which one controls it best.
Dr. Bedi uses the EP study to:
Implantable cardioverter defibrillators (ICD)
An ICD is an electronic device that constantly monitors your heart rate and rhythm. When it detects a very fast, abnormal heart rhythm, it delivers energy to the heart muscle. This causes the heart to beat in a normal rhythm again.
How an ICD works
The ICD is an amazing little computer. It monitors the heart rhythm, identifies abnormal heart rhythms, and determines the appropriate therapy to return the patient’s heartbeat to a normal heart rhythm.
Why an ICD?
ICDs are used for those: who have had an episode of ventricular fibrillation; who have had a heart attack and are at high risk for sudden cardiac death; who have hypertrophic cardiomyopathy and are at high risk; or with at least one episode of ventricular tachycardia.
Pacemaker
A pacemaker is a small device that sends small electrical impulses to the heart muscle to maintain a suitable heart rate or to stimulate the lower chambers of the heart (ventricles). A pacemaker may also be used to treat fainting spells and congestive heart failure.
Dr. Bedi will decide what type of pacemaker is needed based on the patient’s heart condition. Dr. Bedi also determines the minimum rate to set the patient’s pacemaker. When the patient’s heart rate drops below the set rate, the pacemaker generates an impulse that passes through the lead to the heart muscle. This causes the heart muscle to contract, creating a heartbeat. |
