Pacemakers and Defibrillators

Irregular heartbeats can be dangerous if not detected and treated promptly. At HeartCare Texas, we specialize in the advanced management of heart rhythm disorders through the use of pacemakers and defibrillators. These life-saving devices are designed to regulate and monitor your heart's electrical activity, ensuring it beats at a proper rate and rhythm.

Our experienced cardiologists are committed to providing comprehensive care, from the initial diagnosis and personalized treatment plans to the precise implantation of these devices and ongoing follow-up care.

What are pacemakers and defibrillator implants?

Pacemakers and defibrillators are devices designed to monitor and regulate heart rhythms using electrical shocks, ensuring a stable heartbeat.

Pacemakers 

Pacemakers are devices that send electrical impulses to the heart to prevent it from beating too slowly. They are implanted surgically and activated when needed, particularly during episodes of bradycardia (a slow heartbeat). Pacemakers consist of a pulse generator to control the rate of electrical impulses and electrodes that transmit these signals to the heart chambers.

Defibrillators (ICDs)

Also known as implantable cardioverter-defibrillators, these devices are connected to the heart to detect rapid or abnormal heartbeats. They deliver electrical shocks to restore the heart's normal rhythm during tachycardia (abnormally fast heart rate), reducing the risk of cardiac arrest. Additionally, ICDs can function as pacemakers to correct slower heartbeats, ensuring overall heart health and safety.
 

When is a pacemaker and defibrillator used?

Pacemakers are implanted beneath the collarbone and are prescribed by physicians to:

• Control bradycardia (slow heartbeat)
• Reduce the risk of heart failure post-heart attack
• Restore heart rhythm after surgery or medication adjustments

Implantable Defibrillators (ICDs) are implanted in patients at risk of life-threatening rapid heart rhythms and are necessary to:

• Monitor individuals who have survived cardiac arrests
• Correct ventricular tachycardia (rapid heartbeat)
• Prevent potential heart failure
• Monitor individuals with a family history of heart conditions
   

Are there any risks associated with a pacemaker and defibrillator?

Implanting a pacemaker or defibrillator involves some rare risks and complications. Patients should communicate any concerns or medical conditions to their physician, especially if they are pregnant, breastfeeding, allergic to medications, or have any underlying health issues.

Risks related to pacemaker surgery:

• Blood clots or damage near the pacemaker
• Collapsed lung
• Infection, swelling, or bleeding near the pacemaker
• Abnormal heart rhythms
   

Potential risks of defibrillator surgery:

• Wound infection
• Injury to the heart or collapsed lung
• Bleeding or damage to the blood vessel where the catheter is inserted
• Unexpected dangerous heart arrhythmia
   

What are the preparations needed for a pacemaker and defibrillator?

Before undergoing pacemaker or defibrillator surgery, patients should inform their physicians about any medication allergies, latex allergies, or pregnancy. It's also important to disclose all prescription medications. Brief fasting may be necessary before the procedure, and physicians will provide additional instructions as needed.

Diagnostic tests for irregular heartbeat

To diagnose irregular heartbeats, patients may undergo various tests, including an electrocardiogram (ECG), echocardiogram, Holter monitoring, stress test, and others.
 

Post-procedure precautions

After the procedure, patients should avoid vigorous exercise and heavy lifting for approximately six months. Additionally, they should take precautions around cell phones, power-generating equipment, and other devices as instructed by their healthcare provider.
