Cardiac Pacing & Device Implantation: Expert Insights by Dr. Debopriyo Mandal
The human heart relies on a natural electrical system to maintain a steady rhythm. When this system malfunctions, it can lead to arrhythmias—irregular heartbeats that may cause dizziness, fainting, heart failure, or even sudden cardiac arrest. Cardiac pacing and device implantation have revolutionized heart care by restoring normal rhythm and improving survival rates.
Dr. Debopriyo Mandal, an experienced cardiologist, sheds light on the significance of pacemakers, implantable cardioverter defibrillators (ICDs), and cardiac resynchronization therapy (CRT) devices in managing heart rhythm disorders.
What is Cardiac Pacing?
Cardiac pacing is a procedure where an electronic device—such as a pacemaker or defibrillator—is implanted to regulate abnormal heart rhythms. These devices help the heart maintain a steady and healthy beat, preventing complications.
Types of Cardiac Devices
1️⃣ Pacemakers: Used for slow heart rhythms (bradycardia), pacemakers send electrical impulses to the heart to maintain a normal heart rate.
2️⃣ Implantable Cardioverter Defibrillators (ICDs): ICDs detect and correct life-threatening fast heart rhythms (ventricular tachycardia or fibrillation) by delivering electrical shocks.
3️⃣ Cardiac Resynchronization Therapy (CRT) Devices: CRT is used for heart failure patients with uncoordinated heartbeats, improving heart function and reducing symptoms.
Who Needs a Cardiac Device Implantation?
Dr. Debopriyo Mandal recommends cardiac pacing and device implantation for patients experiencing:
✔ Bradycardia (slow heart rate leading to fatigue, dizziness, or fainting)
✔ Heart block (a delay or blockage in electrical signals within the heart)
✔ Atrial fibrillation with slow ventricular response
✔ Ventricular tachycardia or fibrillation (life-threatening fast rhythms)
✔ Heart failure with poor synchronization of heart contractions
The Implantation Procedure: Step-by-Step
🔹 Pre-Procedure Assessment: Doctors perform ECGs, echocardiograms, and Holter monitoring to determine the need for implantation.
🔹 Device Implantation: A small incision is made near the collarbone, and the device is placed under the skin. Leads are guided into the heart chambers through blood vessels.
🔹 Post-Procedure Recovery: The device is programmed to suit the patient’s needs, and follow-ups ensure proper functioning.
Life After Cardiac Device Implantation
With proper care, patients with pacemakers or ICDs can lead healthy, active lives. Dr. Debopriyo Mandal advises:
✔ Avoiding strong electromagnetic fields (like MRI machines or high-voltage power lines)
✔ Following a heart-healthy lifestyle with regular exercise and a balanced diet
✔ Attending routine check-ups to monitor the device’s function
Conclusion
Cardiac pacing and device implantation are life-saving advancements in cardiology, offering hope to patients with severe heart rhythm disorders. If you or a loved one experiences palpitations, dizziness, or unexplained fainting, consult Dr. Debopriyo Mandal for expert guidance and treatment.
