This paper describes a substantial part of the international mentoring network of students and young investigators in electrocardiology that developed around Dr. Galen Wagner (1939-2016), including many experiences of his mentees and co-mentors. The paper is meant to stimulate thinking about international mentoring as a means to achieve important learning experiences and personal development of young investigators, to intensify international scientific cooperation, and to stimulate scientific production.

Multimodal source imaging is an emerging field in biomedical engineering. Its central goal is to combine different imaging modalities in a single model or data representation, such that the combination provides an enhanced insight into the underlying physiological organ, compared to each modality separately. It requires advanced signal acquisition and processing techniques and has applications in cognitive neuroscience, clinical neuroscience and electrocardiology. Therefore, it belongs to the heart of biomedical engineering...

INTRODUCTION: The American Heart Association recommends individuals with symptoms suggestive of acute coronary syndrome (ACS) activate the Emergency Medical Services' (EMS) 911 system for ambulance transport to the emergency department (ED), which enables treatment to begin prior to hospital arrival. Despite this recommendation, the majority of patients with symptoms suspicious of ACS continue to self-transport to the ED. The IMMEDIATE AIM study was a prospective study that enrolled individuals who presented to the ED with ischemic symptoms...

OBJECTIVE: Familial mediterranean fever (FMF) is the most common auto-inflammatory disease that is characterized by recurrent, self-limited attacks of fever and serous membrane inflammation. Patients with inflammatory rheumatic diseases are considered to have a raised cardiovascular diseases risk. The aim of this study was to investigate; by means of P wave dispersion (Pd) and QT dispersion (QTd) parameters detected by simple standard electrocardiogram (ECG), atrial and ventricular repolarization changes in pregnant women with and without FMF...

Recent progress in cardiac catheterization and devices has allowed the development of new therapies for severe cardiac diseases like arrhythmias and heart failure. The skills required for such interventions are very challenging to learn, and are typically acquired over several years. Virtual reality simulators may reduce this burden by allowing trainees to practice such procedures without risk to patients. In this paper, we propose the first training system dedicated to cardiac electrophysiology, including pacing and ablation procedures...

BACKGROUND: P waves reported in electrocardiology literature uniformly appear smooth. Computer simulation and signal analysis studies have shown much more complex shapes. OBJECTIVE: We systematically investigated P-wave complexity in normal volunteers using high-fidelity electrocardiographic techniques without filtering. METHODS: We recorded 5-min multichannel ECGs in 16 healthy volunteers. Noise and interference were reduced by averaging over 300 beats per recording...

André, Julien, Auguste Jouve was born in Marseilles on June 10, 1909 son of Xavier Marie Francois Louis Jouve MD and Marie Louise Charlotte Vigliengo his wife. He had a brilliant medical career in Marseilles: Resident at Marseilles Hospitals in 1931, major of his promotion, then an Assistant in 1943 and a Chief in 1951, to become Associate Professor of Medicine in 1946 and finally Full Professor of Clinical and Experimental Cardiology in 1954. Fellow of several Cardiological Societies, he became President of the French Society of Cardiology in 1968, Vice-President of the European Society of Cardiology in 1972 and finally President of the French College of Vascular Pathology in 1973...

Robust Generalised Cross-Validation was proposed recently as a method for determining near optimal regularisation parameters in inverse problems. It was introduced to overcome a problem with the regular Generalised Cross-Validation method in which the function that is minimised to obtain the regularisation parameter often has a broad, flat minimum, resulting in a poor estimate for the parameter. The robust method defines a new function to be minimised which has a narrower minimum, but at the expense of introducing a new parameter called the robustness parameter...

At the April, 2015 International Society for Computerized Electrocardiology (ISCE) Annual Conference in San Jose, CA, a special session entitled Remembering Ron & Rory was held to pay tribute to the extraordinary work and lives of two experts in electrocardiology. The session was well attended by conference attendees, Childers' family members and friends, and additional colleagues who traveled to San Jose solely to participate in this session. The purpose of the present paper is to document the spirit of this special session as faithfully as possible using the words of the session speakers...

BACKGROUND: Little is known about time-dependent changes in QT dynamics after initiation of atrial fibrillation (AF) and after restoration of sinus rhythm (SR) in patients with paroxysmal AF. METHODS: Beat-to-beat QT and RR intervals in CM5 lead were measured automatically in 13 patients with both AF and SR on the single 24-hour Holter electrocardiology recording. QT-RR relation was analyzed at six periods of time: 1 hour before AF onset (Pre(0-1h)), 0-1 hour and 4-5 hours after AF onset (AF(0-1h) and AF(4-5h)), and 0-1 hour, 2-3 hours, and 4-5 hours after the restoration of SR (SR(0-1h), SR(2-3h), and SR(4-5h))...

For several decades we have observed the development of data transmission technology on an unprecedented scale. With the development of such technology there has also appeared concepts on the use of these solutions in health care systems. Over the last decade telemedicine has been joined by the concept of mHealth, which is based on mobile devices mainly to monitor selected biomedical parameters. On 10 October 2014, during the conference Baltic Electrocardiology Autumn - Telemedicine and Arrhythmia (BEATA), a debate was held with the participation of physicians, politicians, businessmen, and representatives of the Government (Ministry of Health, National Health Fund, Social Insurance Institution) concerning the use of telecardiology services in daily practice...

BACKGROUND: Screening athletes with ECGs is aimed at identifying "at-risk" individuals who may have a cardiac condition predisposing them to sudden cardiac death. The Seattle criteria highlight QRS duration greater than 140 ms and ST segment depression in two or more leads greater than 50 μV as two abnormal ECG patterns associated with sudden cardiac death. METHODS: High school, college, and professional athletes underwent 12 lead ECGs as part of routine pre-participation physicals...

AIMS: The Thebesian valve (TV) can be a significant obstacle to coronary sinus (CS) cannulation. The aim of this study was to evaluate the characteristic features of the CS valve--TV anatomy. In particular, emphasis was placed on identifying specific structures of the TV that could potentially complicate CS cannulation. METHODS AND RESULTS: We examined 273 autopsied human hearts. The height of the TV and the diameter of the CS were measured. The valves were classified according to their shape into five types: remnant, semilunar, fold, cord, and mesh and fenestrated...

Over 10 years ago, the standards for cardiac monitoring were set forth by the Councils on Cardiovascular Nursing, Clinical Cardiology, and Cardiovascular Disease in the Young. The standards were endorsed by the International Society of Computerized Electrocardiology and the American Association of Critical-Care Nurses. The American Heart Association printed the standards as an American Heart Association Scientific Statement. The standards provided direction related to remote telemetry monitoring to acute care hospitals...

OBJECTIVE: The purpose of this research was to study P wave parameters to determine the association between preeclampsia and future cardiovascular risk and to study the possible correlation between P waves and severity of preeclampsia. STUDY DESIGN: In this case-control study 58 pregnant women with preeclampsia and 30 normal pregnant women were compared by measuring maximum and minimum P-wave durations and P-wave dispersion (Pd) in the late third trimester. RESULTS: Minimum P wave values were lower and Pd values were higher, both significantly, in the preeclampsia groups than in the control group...
