Electrophysiology in India
From the desk of Secretary, IHRS: Heartfelt thanks to special friends Dr Pawan Suri, Dr Deepak Padmanabhan, Dr Avinash Verma, Dr Suchit Majumdar, and Dr Shunmuga Sundaram for all their help and contributions toward the IHRS website.
Cardiac electrophysiology is the discipline of elucidating, diagnosing, and treating the electrical activities of the heart. Although relatively new, it is one of the fastest progressing fields in medicine. The language of electrophysiologists is based upon an electrocardiographic interpretation in form of “p QRS T” which they decipher and interpret with perfection.
The first electrocardiography (ECG) machine was used in K.E.M. Hospital, Mumbai in the late 40's. Invasive Cardiac Electrophysiology was initiated in GB Pant Hospital and AIIMS. The first electrophysiology lab was established on 5th March, 1975 at G.B. Pant Hospital, Delhi by Dr M Khalilullah.
Cardiac pacing in India dates back to late 1960s. First cardiac pacing in India was reported by the team of Dr CC Kar and Dr AK Basu from IPGME&R, Calcutta in 1966–67. The first permanent pacemaker manufactured in India was from Pacetronix and implanted on 9th Sept, 1994 at Kasturba Hospital, Bhopal.
India has done substantial progress in electrophysiology over the last two decades. The major contribution to the world of Cardiac Electrophysiology started after the advent of Indian Heart Rhythm Society in year 2006 which laid the foundation of this branch in India in a formulated fashion.
History of Electrophysiology
Cardiac electrophysiology is the science of understanding the electrical system of heart and at the same time diagnosing and treating the dysrhythmias. Although foundation for the study of arrhythmias was laid by Chinese pulse theory way back in 5th century BC, the most significant breakthrough in this field has occurred in twentieth century only.
The human electrocardiogram was first recorded in 1897. His bundle electrogram was recorded in 1969, considered to be a major breakthrough in the field. DC energy catheter ablation emerged in 1981 and radiofrequency catheter ablation in 1990.
The treatment of bradyarrhythmias has revolutionised over the last six decades. The first pacemaker was implanted in Sweden in 1958. Developments now include rate responsive pacing, wireless remote monitoring, MRI compatibility, leadless pacemakers and His bundle pacing.
Implantable cardioverter defibrillators (ICD) and biventricular pacing have extended electrophysiology beyond arrhythmias to chronic heart failure and survivors of sudden cardiac death.
