The Conductor of the Heart: When the Electrical Metronome Fails
The heart is both a mechanical pump and an electrical marvel. An intrinsic network of specialized conduction tissue, starting at the sinus node and branching through the atrioventricular (AV) bundle, coordinates 100,000 synchronized beats every single day.
When this natural metronome degenerates due to aging, fibrosis, previous heart attacks, or medication toxicity, the heart's pacing falls into disarray. Severe conduction failure leads to sudden drops in cerebral perfusion, triggering frightening blackouts (Stokes-Adams attacks), debilitating exhaustion, memory fog, or fatal asystole.
At Yashoda Medicity, Indirapuram, Dr. Manish Aggarwal directs a comprehensive cardiac rhythm device program. From traditional dual-chamber pacemakers to advanced physiological conduction system pacing (His-bundle and Left Bundle Branch Area Pacing / LBBAP), our focus is restoring natural, synchronized cardiac cadence.
The Micra Revolution: The World's Smallest Invisible Pacemaker
Conventional pacemakers require a surgical incision beneath the collarbone to fashion a subcutaneous 'pocket' for the battery generator, along with insulated transvenous leads threaded through veins into the heart chambers. While effective, traditional pacemakers leave a visible bump under the skin and carry risks of lead fracture, venous thrombosis, and pocket infections.
Dr. Manish Aggarwal offers the Medtronic Micra Transcatheter Pacing System, an engineering breakthrough 93% smaller than a conventional pacemaker and roughly the size of a large vitamin capsule.
- Zero Chest Incision & No Visible Bump: The entire self-contained pacemaker is delivered through a catheter in the femoral vein and anchored directly into the right ventricle.
- No Transvenous Wires: Eliminates lead dislodgement, vascular occlusion, and lead-related complications entirely.
- Zero Physical Restrictions: Patients do not face the post-implant shoulder immobility or arm restrictions required with traditional pacemakers, returning to swimming, golf, and active workouts immediately.
Cardiac Resynchronization Therapy (CRT) for Congestive Heart Failure
In patients with severe dilated cardiomyopathy or heart failure accompanied by a widened QRS complex (Left Bundle Branch Block), the left and right ventricles contract asynchronously. The walls fight each other rather than pumping blood forward, drastically worsening pump failure.
Dr. Aggarwal implants Cardiac Resynchronization Therapy (CRT-D / CRT-P) devices. By pacing both ventricles simultaneously, CRT restores harmonious biventricular contraction. This electrical realignment often produces dramatic rebounds in Ejection Fraction (EF), relieves severe breathlessness, and substantially reduces hospitalizations.
"Whether deploying an invisible leadless Micra or resynchronizing a failing heart with CRT, our goal is seamless physiological restoration so patients can forget they have a device at all."
Who Is an Ideal Candidate for Pacemakers & Implantable Devices?
Patients meeting these diagnostic and clinical profiles receive targeted evaluations under Dr. Manish Aggarwal at Yashoda Medicity:
- Patients suffering from symptomatic bradycardia (pulse rate dropping below 40–50 bpm), severe fatigue, lightheadedness, or sudden unexplained fainting (syncope).
- Individuals diagnosed with Sick Sinus Syndrome, High-Grade AV Block, or Complete Heart Block requiring reliable physiological pacing.
- Heart failure patients with reduced ejection fraction (EF < 35%) and left bundle branch block (LBBB) who need Cardiac Resynchronization Therapy (CRT).
- Survivors of sudden cardiac arrest or patients with life-threatening ventricular tachycardia (VT) who require an Implantable Cardioverter Defibrillator (ICD).
- Active or cosmetic-conscious patients seeking the world's smallest leadless pacemaker without a surgical chest pocket or visible scar.
Frequently Asked Questions
What is the primary difference between a traditional pacemaker and the Micra leadless pacemaker?
A traditional pacemaker consists of a pulse generator placed under the chest skin with wires running through veins into the heart. The Micra has no wires, no surgical chest pocket, and sits entirely inside the heart chamber. It is placed through a leg vein puncture, leaving no scar on the chest and no visible device bump.
Can I safely undergo an MRI scan with a modern pacemaker?
Yes. All pacemakers, ICDs, and CRT devices implanted by Dr. Manish Aggarwal are 100% MRI-conditional. When placed in MRI mode by our cardiology team, patients can safely undergo both 1.5 Tesla and 3.0 Tesla MRI scans without risk of device malfunction.
How long does a modern pacemaker battery last?
Contemporary pacemakers feature advanced lithium-carbon monofluoride batteries lasting between 10 and 15+ years depending on pacing percentage. Our devices incorporate wireless home telemetry monitors that communicate daily battery and lead status directly to our clinical portal.
