Best Pacemaker Doctor in Ghaziabad & Leadless Pacemaker Specialist in Delhi NCR
A pacemaker (cardiac pacing device) is a small device implanted in the chest to support the heart’s electrical system and help control the heartbeat. It is used to manage irregular heart rhythms and prevent the heart from beating too slowly.
Pacemakers – How They Work
The heart has an electrical system that signals each chamber when to contract. When this system fails, the chambers may pump out of sequence, affecting normal blood flow. Pacemakers deliver electrical impulses to monitor and ensure the heart beats properly and distributes blood as needed by the body.
Dr. Vivek Kumar – Director, Interventional Cardiology & Head of Structural Heart Program at Max Super Speciality Hospital, Vaishali – is widely regarded as one of the best pacemaker implantation doctors in Ghaziabad and Delhi NCR. He handles both conventional and leadless pacemaker cases with high expertise.
When do you need a Pacemaker?
- Chest pain (angina)
- Tachycardia – fast heartbeat
- Bradycardia – slow heartbeat
- Irregular heartbeat (arrhythmia)
- Heart palpitations
- Shortness of breath
- Unexplained dizziness, light-headedness, nausea or fainting
- Unexplained confusion
- Swelling in legs or feet
How do Pacemakers work?
The heart’s electrical system tells all chambers when to contract. When this system malfunctions, the chambers may pump in the wrong order, disrupting normal blood flow. Pacemakers use electrical impulses to check and ensure the heart works correctly and that blood is distributed as required by the body.
Types of Pacemaker
- Leadless pacemaker: A tiny pacemaker is inserted and attached to an inner wall of the heart. No leads (wires) are required.
- Single-chamber pacemaker: Sends electrical impulses to the right ventricle via a single lead.
- Dual-chamber pacemaker: Sends impulses to both the right atrium and right ventricle to coordinate timing between chambers.
- Biventricular pacemaker (CRT): Uses three leads – two connected to the lower chambers (ventricles) and one to the right upper chamber (atrium) – for cardiac resynchronization therapy.
Tests performed before Pacemaker Implantation
- Electrocardiogram (ECG or EKG)
- Holter monitoring
- Echocardiogram
- Stress test
Why is a Pacemaker advised?
- When the heartbeat is not adequate for the body’s needs, a pacemaker helps control the rhythm and electrical conduction.
- A temporary pacemaker may be recommended after a heart attack if the heartbeat is slow.
- After a heart attack
- After certain surgeries
- Medication-related slow heart rate
- Situations where the rhythm may return to normal
- A permanent pacemaker is advised when:
- There is continuous or chronic slow/irregular heartbeat
- Heart failure is present
Possible Risks after the Procedure
- Infection at the implant site
- Swelling, bruising or bleeding near the pacemaker
- Blood clots (thromboembolism)
- Damage to blood vessels
- Collapsed lung (pneumothorax)
- Hemothorax
