Who Needs a Pacemaker or ICD? An Interventional Cardiologist Explains
Heart rhythm problems, also known as arrhythmias, can significantly affect a person’s quality of life - and in severe cases, may be life-threatening.
Thankfully, medical science has developed highly effective devices like pacemakers and implantable cardioverter-defibrillators (ICDs) to help regulate abnormal heart rhythms. But who really needs these devices? What’s the difference between them? And how are they implanted?
To answer these critical questions, we turn to Dr. A Sai Ravi Shanker, one of the most accomplished interventional cardiologists in India and currently serving as the HOD and Senior Consultant Cardiologist at Aster Prime Hospitals, Ameerpet, Hyderabad.
With more than 20 years of experience and over 20,000 cath lab procedures to his name, Dr. Shanker is regarded as the Best Cardiologist in Hyderabad, especially for complex cardiac interventions like pacemaker and ICD implantations.
Understanding Pacemakers and ICDs
Both pacemakers and ICDs are small electronic devices implanted under the skin, typically near the collarbone, and connected to the heart with thin wires called leads. However, their functions differ:
Pacemaker: Designed to keep the heart beating at a normal rate and rhythm, primarily used for bradycardia (slow heart rate) or heart block.
ICD (Implantable Cardioverter Defibrillator): Monitors heart rhythm and delivers an electric shock if it detects a life-threatening arrhythmia such as ventricular tachycardia or ventricular fibrillation.
Some patients may receive biventricular devices or dual-chamber ICDs, especially if they have heart failure or significant structural heart issues.
Who Needs a Pacemaker?
You may need a pacemaker if you suffer from:
Bradycardia: A condition where your heart beats too slowly, leading to dizziness, fatigue, or fainting.
Heart Block: A delay or complete block in the electrical signals that control heartbeats.
Sick Sinus Syndrome: A malfunction in the heart’s natural pacemaker.
Post-Cardiac Procedure Arrhythmias: Some patients develop rhythm disorders following heart surgeries or catheter interventions
Dr. Sai Ravi Shanker, a renowned Interventional Cardiologist in Ameerpet, performs leadless pacemaker implantation, a cutting-edge technique that avoids traditional lead wires and offers quicker recovery with fewer complications.
Who Needs an ICD?
An ICD may be recommended for patients who are at high risk of sudden cardiac death due to:
History of Cardiac Arrest or Ventricular Arrhythmias
Severely Reduced Ejection Fraction (<35%)in Heart Failure
Genetic Arrhythmia Syndromes like Long QT Syndrome or Brugada Syndrome
Survivors of Sudden Cardiac Arrest
ICDs are often life-saving for patients who have suffered from Acute Coronary Syndrome (ACS) or have other underlying heart muscle diseases.
As part of Acute Coronary Syndrome (ACS) Treatment in Hyderabad patients are thoroughly evaluated for arrhythmia risks, and ICDs are advised when appropriate.
Implantation and Recovery
Both pacemaker and ICD implantation procedures are performed in a catheterization lab under local anesthesia. Patients usually go home within 24 - 48 hours and return to normal activities within a week or two.
Follow-ups include device programming, battery checks, and occasional imaging to monitor lead placement.
At Aster Prime Hospitals, Dr. Shanker and his team use advanced imaging techniques like IVUS/OCT to ensure precise placement and minimal risk. Their patient-centric approach ensures personalized care before, during, and after the procedure.
Pacemakers and Aortic Conditions
Patients with aortic valve disorders, aneurysms, or those undergoing structural interventions like TAVR (Transcatheter Aortic Valve Replacement) may sometimes require pacemakers due to damage or pressure on the heart’s electrical pathways.
Dr. Shanker’s expertise in Aortic Aneurysms and Dissections Treatment in Hyderabad allows him to comprehensively assess and manage these complexities, ensuring both vascular and electrical heart functions are well cared for.
Advances in Interventional Cardiology: A Combined Approach
Dr. Sai Ravi Shanker is not just skilled in device implantation; he is a pioneer in combining interventional cardiology with structural and electrical heart therapies. From rotablation to ASD/PDA closures, his holistic approach ensures that patients get all-encompassing care under one roof.
For patients seeking Aortic Aneurysms and Dissections Treatment in Hyderabad Aortic Aneurysms and Dissections Treatment in Hyderabad, timely diagnosis and interventions—whether endovascular or surgical - are vital. Sometimes, post-procedure arrhythmias can emerge, requiring pacemaker implantation. Dr. Shanker’s dual expertise ensures such transitions are seamless.
Likewise, those undergoing Acute Coronary Syndrome (ACS) Treatment in Hyderabad often face the risk of arrhythmias post-stenting or heart muscle damage. Having access to a highly experienced interventional cardiologist who can manage both revascularization and rhythm correction can make a critical difference in outcomes
Why Choose Dr. Sai Ravi Shanker?
