Treatment of Cardiac Arrhythmias at McLaren Port Huron

At McLaren Port Huron, a multitude of treatment options are available for your heart condition. 

Your doctor and you will decide what is the best option for your heart health. Treatments include:


A variety of medications are used to treat abnormal heart rhythms and related conditions. Sometimes medications are used in combination with Cardiac Implantable Electronic Devices (CIEDs). Antiarrhythmics are a class of medication commonly used to treat abnormal heart rhythms. Other types of medications may also be administered to reduce the risk of blood clots in patients with certain types of arrhythmias.

Implantable Cardioverter

An Implanted Cardioverter Defibrillator (ICD) is a device that is implanted in a patient’s body to help control the heart’s rhythm. ICDs are extremely effective in stopping dangerous arrhythmias and are the most effective therapy for treating ventricular fibrillation, the major cause of sudden cardiac death. The ICD continuously monitors the heart rhythm and delivers a “pacemaker” shock when the heart rhythm gets too slow. If the heart rhythm gets dangerously fast, the ICD can deliver a life-saving shock that returns the heart to a normal rhythm. 

Electrical system of heartPacemaker

The heart has a natural “pacemaker” that regulates electrical impulses in the heart. This natural “pacemaker” is called the sinoatrial node. But sometimes the sinoatrial node does not work properly and an artificial pacemaker is needed to regulate the heart’s rhythm. An implantable pacemaker device continuously monitors the rhythm of the heart and transmits electrical impulses to stimulate the heart if it is beating too slowly or unevenly.

Bi-Ventricular Pacing

Bi-Ventricular devices stimulate the left and right ventricles simultaneously, the bi-ventricular pacing system resynchronizes the heart and dramatically improves the heart’s ability to pump blood through the body. 

Cardiac Ablation

An irregular heartbeat (arrhythmia) can be caused by a small section of damaged tissue in the heart. In a cardiac ablation procedure, a catheter is used to guide tiny electrodes into the heart. When the damaged tissue is identified, a burst of radiofrequency energy destroys the tissue that is causing the abnormal electrical signals. With the damaged tissue destroyed, the heart usually returns to a normal rhythm.
