Irregular Heart Rhythm Treatment: An Overview

Has your heart ever beaten rapidly or slower than normal? You could be having an arrhythmia or an irregular heart rhythm. Arrhythmias are common, and millions of people experience these abnormal heartbeats at some point in their lives.

Heart arrhythmias occur when your heart’s electrical signals coordinating your heartbeats do not work properly. The best medical solution to restore your normal heartbeat is to undergo heart rhythm procedures that examine how and why your heart is pumping abnormally.

Dr. Karthigesan is the right specialist for treating irregular heart rhythms. He is a Senior Consultant Cardiologist, Cardiac Device and Electrophysiology Specialist certified by the International Board of Heart Rhythm Examiners, USA.

Besides his experience performing thousands of heart rhythm procedures, Dr. Karthigesan is also well-known for pioneering work in interventional cardiology and device therapy. He is an expert in performing complex ablation procedures involving radio frequency, pacemakers and devices, and revisions of existing devices. As a transthoracic and transesophageal echocardiographer, he has extensive experience in interventional cardiac procedures, such as coronary angiograms.

While performing a heart rhythm procedure, Dr. Karthigesan will attempt to treat heart arrhythmia to minimise your symptoms and disease progression. He will further test your heart condition with the latest mapping technology and cardiac catheters.

Benefits of
Heart Rhythm Treatment

Improves quality of life
Irregular heart rhythm treatment ensures your well-being is not affected by repeated palpitations caused by arrhythmias or emergency hospitalizations.
Prevents sudden cardiac death
Certain heart rhythm disorders or genetic heart issues may not be severe in everyday life, but they can result in sudden cardiac arrest. Either RF ablation or AICD implantation saves lives.
Prevents disabling stroke
Abnormal heart rhythm treatment rectifies Atrial Fibrillation, the commonest rhythm disorder, increases the brain stroke risk by many folds and causes disabling symptoms.
Prevents repeated hospitalisation
Abnormal heart rates can cause symptoms like palpitation, loss of consciousness, chest pain and breathlessness, bringing the patient to the emergency room.
Prevents the need for lifetime medication
Most heart rhythm disorders are curable by advanced 3D mapping technology guided by Radiofrequency catheter ablation procedures, making it more cost-effective than lifelong medications.

Types of Heart Rhythm Disorder Treatment Procedures

The EP study(EPS) investigates the heart’s electrical system and functions to identify abnormal heart rhythms requiring treatment. You need to undergo EP study as a preliminary test to detect the arrhythmias before going for cardiac ablation. Dr. Karthigesan may also recommend the EP study if you have fast, slow, or irregular heartbeat, recurrent syncope, or high risk of sudden cardiac death.

In this procedure, Dr. Karthigesan will use heat or cold energy to obstruct the electrical pathways and restore a normal heartbeat. Cardiac ablation is of two types:

Radiofrequency (RF) Catheter Ablation
In RF ablation, radiofrequency energy is delivered to the heart through catheters to detect and heat the abnormal heart tissues causing irregular heartbeat.

Learn More

Cryo Catheter Ablation
This is a less invasive medical procedure that utilises freezing energy (cryo) instead of heat to precisely disable specific heart tissue causing irregular heartbeats.

Common cardiac arrhythmias that need cardiac ablation procedure:

PSVT – RF Ablation
PSVT or SVT ablation creates tiny scars in the heart using cold or heat energy to block faulty electrical signals.

Learn More

Atrial Flutter Ablation
In atrial flutter ablation, scar tissues are created in the upper chambers of your heart. These scars will block the abnormal heart signals causing atrial flutter.

Learn More

Atrial Fibrillation Ablation
Similar to SVT ablation, atrial fibrillation ablation also uses heat or cold energy to generate tiny scars in the pulmonary vein ostia to block abnormal electrical impulses and bring the heartbeat back to normalcy.

Learn More

Ventricular Tachycardia [VT] Ablation
Here again, Dr. Karthigesan will utilise heat energy to make small, imperceptible scars that will block faulty electrical signals and restore the normal heartbeats.

Pacemakers, automated Implantable Cardioverter Defibrillators or ICDs are some of the most common electronic devices surgically inserted into the chest to aid in the better functioning of the heart. These devices also track your heart rate and to treat serious cardiac conditions that impact your health. Dr Karthigesan may recommend the following devices:

  • A permanent pacemaker generates electrical signals that keep your heart beating at a normal rate.
  • An automated ICS to track your heart rate throughout the day and identify and rectify dangerous arrhythmias.

Heart Rhythm Procedures: Deeper Insights

  • AVNRT
  • WPW syndrome
  • Atrial Flutter
  • Ventricular tachycardia
  • Complete heart blocks (CHB)
  • Atrial fibrillation (irregular rhythm)
  • Slow heart rate or Bradycardia, less than 60 bpm
  • Fast heart rate or Tachycardia, more than 100 bpm
  • Premature ventricular contractions (PVCs)
  • Genetic arrhythmias or Channelopathies such as Brugada syndrome and Long QT syndrome
  • Heart palpitations such as skipped beats, extra beats and racing beats.
  • Breathing difficulty or Dyspnea
  • Syncope or fainting spells
  • Surviving a Sudden Cardiac Arrest

You are at a high risk of arrhythmia if you:

  • Smoke or use other tobacco products
  • Consume excessive amounts of alcohol
  • Consume too many caffeinated beverages
  • Consume herbal supplements and cold medicines
  • Have Hypertension and Diabetes
  • Have a high Body Mass Index (higher than 30)
  • Have Obstructive Sleep Apnea
  • Family history of cardiac arrhythmia
  • Family history of sudden cardiac arrest
It is best to consult a cardiologist who specialises in Electrophysiology. Dr. Karthigesan is a renowned cardiologist, Certified Electrophysiology Specialist or CEPS and Certified Cardiac Device Specialist. He has extensive experience as an Electrophysiologist, having treated many patients with arrhythmia disorders. Under Dr. Karthigesan’s care, you will get the best possible treatment for your heart rhythm disorders.

The heart conditions that predispose to heart rhythm disorders are:

  • The electrical malfunction that occurs due to a developmental anomaly in the electrical system in your heart. This malfunction may cause the heart to beat too fast or too slow. Sometimes, it may also beat irregularly and in a disorganised way.
  • Heart attack caused due to blockages in the arteries supplying blood to the heart. Either during an acute heart attack or subsequently, after many years, damaged muscles (scar) can create electrical instability and cause sudden cardiac arrest.
  • Structural abnormality in the heart due to diseases like Cardiomyopathy and congenital heart diseases or Genetic abnormality in the cardiac electrical system like channelopathies can cause life-threatening cardiac arrhythmia.
  • Structural changes happen in the heart due to aging as well due to many non-communicable diseases like Hypertension etc. It can lead to abnormal heartbeat- the heart will beat either too fast and irregularly or too slow.
