Günter Breithardt

Breithardt is a founding member and was chairman of the Atrial Fibrillation Competence Network (AFNET), an internationally recognised research platform on atrial fibrillation, from 2003 to 2015. AFNET was funded by the BMBF until 2014 as part of the Competence Networks in Medicine; since then it has been an independent academic research platform, which has been cooperating with the German Centre for Cardiovascular Research (DZHK) since January 2015. Through seven international consensus conferences, AFNET, together with partner EHRA, has contributed to the direction of international research in this field.

At the University of Düsseldorf, Breithardt was a member of the DFG Collaborative Research Centre SFB 30 Cardiology and co-founder and deputy spokesperson of the subsequent Collaborative Research Centre 242 "Complications of Coronary Heart Disease", including Sudden Cardiac Death, later in Münster founder and spokesperson of SFB 556 "Heart Failure and Arrhythmias - from the Molecular Basis to the Clinic" (1999-2003), co-founder of the Interdisciplinary Centre for Clinical Research (IZKF) and deputy chairman of the BMBF-funded multicentre CAD-REF Registry to record patients with coronary heart disease (CHD) and chronic kidney disease. Chairman of the BMBF-funded multicentre CAD-REF registry for the registration of patients with coronary heart disease (CHD) and chronic kidney disease.

He has contributed to the development of evidence-based guidelines on, among others, on coronary heart disease/angina pectoris (1998), implantation of defibrillators (2000), coronary heart disease and renal failure (2006), interdisciplinary care of adults with congenital heart defects (2006) and treatment of adults with congenital heart defects (2008) as well as a rhythmology curriculum (2012) and a DGK statement on overuse, underuse and misuse (2000).

Breithardt was European representative on the executive board of the International Society and Federation of Cardiology (ISFC), now World Heart Federation (WHF), from 1997 to 1998, member of the executive board of the Council on Clinical Cardiology of the WHF (2005-2008), Vice-chair of the Medical Technology Committee of the Health Research Council of the BMBF (1999-2001), Member of the Scientific Committee and Board of Trustees of the Max Delbrück Center Berlin (since 2000), Vice-chairman (2004–2006) and Chairman of the National Registry for Congenital Heart Defects (2007-2009), Spokesman and executive director of the Competence Network for Congenital Heart Defects (2008-2009), Member of the Board of the German Foundation for Heart Research (2008-2016). From 2008 to 2013, Breithardt was a member of the international advisory board of CARIM, the cardiovascular research centre of Maastricht University. Since 2009, he has been the European representative to the global initiative to raise awareness of the problems caused by atrial fibrillation (AF AWARE) and a member of the international advisory board of the Interuniversitair Cardiologisch Instituut Nederland (ICIN). From 2011 to 2012, he was a visiting professor of the Royal Netherlands Academy of Arts and Sciences at the Netherlands Heart Institute. Since 2011 he has been a member of the international scientific advisory board of CardioVasculair Onderzoek Nederland (CVON). Since 2005, he has been a member of the scientific advisory board of the German Federal Association for Children with Heart Disease.

He also chaired the ESC, AHA and American College of Cardiology (ACC) Task Force on "Standards for analysis of ventricular late potentials using high-resolution or signal-averaged electrocardiography" (1987-1990), which was the first ever joint task force of these three major professional societies.

His pioneering clinical achievements include the world's first catheter ablations of AV conduction and a right-sided accessory pathway with an "incessant" supraventricular reentry tachycardia using radiofrequency current in 1986 in Düsseldorf with the HAT 100 generator developed by Peter Osypka, which allowed a reproducible dose-response curve. He used a catheter with continuous irrigation to prevent clots or overheating of the catheter tip, which later became a standard. The method of ablation using radiofrequency current is now considered standard therapy. Two years earlier, in 1984, he had already been the first in Germany to use an Implantable cardioverter-defibrillator (ICD) - together with the heart surgeons of the University of Düsseldorf. Five years later, in 1989, it was his research group that was the first in the world to implant a 3rd generation ICD.

In the European Society of Cardiology (ESC), Breithardt was Secretary General of the European Congress of Cardiology 1984 in Düsseldorf, Founding Chairman of the Scientific Programme Committee (1986-1990), since 1986 member of the Nucleus of the Working Group on Arrhythmias of the ESC, Founding Chairman of the Research Committee (1990-1992), 1990-2000 member of the Board of the ESC, Councillor-in-Charge of the Working Groups of the ESC (1991-1994), Chair of the Working Group Arrhythmias (1994-1996), founding Chair of the Committee for Clinical and Scientific Initiatives, now Clinical Practice Guidelines (1994-1996), member of the European Affairs Committee (1996-1998) and Chair of the ESC Ethics Committee (from 2017). In 1994, he became the second German cardiologist to be elected President of the Society (term 1996–1998).

In the Deutsche Gesellschaft für Kardiologie (DGK), Breithardt was, among other things. Co-founder - and from 1983 to 1986 chairman - of the working group on arrhythmia diagnostics, member of the commission for clinical cardiology (1985-1997), member of the advisory board of the DGK (1988), co-founder of the Association and later Institute for Clinical Cardiovascular Research (IKKF) (1997–98) as well as Chairman of the Interdisciplinary Task Force on Adults with Congenital Heart Defects (2004-2018), Chairman of the Commission for Scientific Quality (2009-2013) and Chairman of the Task Force on Special Rhythmology (2011-2015). In 1997 he was elected President of the Society (term 1999–2001).

After moving to Franz Loogen's clinic towards the end of 1971, Breithardt was increasingly involved, together with his mentor Ludger Seipel, in the developing field of clinical electrophysiology. He became a leader in the study of sinus node function. Breithardt was one of the pioneers of signal-mediated electrocardiography and developed a comprehensive programme of electrophysiological mapping. His group - together with cardiac surgeons - established one of the largest cohorts of patients undergoing surgery for life-threatening ventricular tachycardia. He has co-edited four editions (1993, 2003, 2009 and 2013) of the standard work Cardiac Mapping for the localisation diagnosis of cardiac arrhythmias.

From 1970, Breithardt worked as a research assistant, first at the Institute of Pathology at the University of Düsseldorf under the direction of Hubert Meessen, and from 1971 at the Medical Clinic and Polyclinic under the direction of Franz Loogen, the doyen of German cardiology. He was recognised as a specialist in internal medicine in 1976 and in cardiology in 1977. In 1978 Breithardt habilitated with a thesis on "Clinical electrophysiological investigations of sinus node function" and became a senior physician at the Medical Clinic and Polyclinic B of the University of Düsseldorf. In 1982 he was appointed professor (C3 for a limited period) at the University of Düsseldorf. There he headed the Electrophysiology Laboratory of the Clinic for Cardiology, Angiology and Pneumology. In 1984 he was appointed professor for life (C3). In 1988 he followed a call to the University of Münster, where he was appointed Professor for Life (C4) and Director of the Medical Clinic and Polyclinic C (Cardiology and Angiology, including Internal Intensive Care Medicine). In 1991 he also took over as head of the "Coronary Heart Disease" department (later: Molecular Cardiology) at the Leibniz Institute for Arteriosclerosis Research at Münster University.

In the Medline database PubMed, Breithardt is named as author or co-author of 961 specialist publications published between 1969 and 2021.

From 1963 to 1968 he studied human medicine at the universities of Tübingen, Vienna and Düsseldorf. With the thesis "Autohistoradiographic studies on the incorporation of H-3 leucine into hypertrophied heart muscle after swimming training" at the Institute of Pathology at the University of Düsseldorf, Breithardt was awarded his doctorate in 1969. He received his licence to practise medicine in 1970. He did his military service in 1971 as a staff physician at the Institute for Military Medicine and Hygiene in Koblenz. Breithardt is married to a Norwegian woman and has a son and a daughter who - in human and veterinary medicine respectively - also specialise in cardiology.

Günter Breithardt (born 19 January 1944 in Haan/Rhineland) is a German physician, cardiologist and emeritus university professor. He is known for his research in the field of rhythmology, especially the diagnosis and pharmacological and non-pharmacological therapy of cardiac arrhythmias and acute cardiac death, in particular the identification of arrhythmia-triggering gene mutations. For 21 years he headed the Medical Clinic and Polyclinic C (Cardiology, Angiology, Intensive Care Medicine) at Münster University Hospital. A number of his academic students hold university management and chief physician positions.
