Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Stuart Connolly, MD, a veteran cardiologist known for his groundbreaking work in the field of electrophysiology, died June 2 after a long battle with neuroendocrine cancer.

Cardiologist Stuart Connolly remembered as a ‘generational thinker,’ electrophysiology pioneer

Connolly spent 40 years at McMaster University as a professor and researcher, founding the school’s cardiac arrhythmia service line and serving as its cardiology chair. He remained active in electrophysiology research until the end of his life.

Paul Zei, MD, director of the comprehensive atrial fibrillation program at Brigham and Women’s Hospital, explained key findings from the late-breaking REAL-AF Registry at the Heart Rhythm Society (HRS) 2024 conference. This registry study evaluated the short- and long-term outcomes of radiofrequency ablation (RF) in treating both paroxysmal atrial fibrillation (PAF) and persistent atrial fibrillation (PsAF), revealing significant advancements in procedural techniques and patient safety. #EPeeps #HRS2024

Interest growing in fluoroscopy-free workflows during RF ablation

Paul Zei, MD, discusses late-breaking data from the REAL-AF Registry, which looked at the short- and long-term outcomes of radiofrequency ablation in paroxysmal and persistent atrial fibrillation.

Embracing AI to enhance EP: Insights from cardiologist Jagmeet Singh

Jagmeet Singh, MD, delivered a keynote address at HRS 2024 on the future of AI in electrophysiology. He spoke to Cardiovascular Business, sharing additional thoughts about the topic.

Heart Rhythm Society (HRS) President Kenneth Ellenbogen, MD, FHRS, director of clinical cardiac electrophysiology and pacing, Virginia Commonwealth University, discussed two key initiatives for 2024-25 with Cardiovascular Business. These include helping create a new, independent cardiovascular medicine board, and supporting the movement toward more outpatient procedures being performed in office-based labs (OBL) and ambulatory surgical centers (ASC). #EPeeps #HRS #HRS24 #HRS2024

Heart Rhythm Society shows support for new cardiovascular board, outpatient EP centers

Cardiovascular Business spoke with HRS President Kenneth Ellenbogen, MD, about two key initiatives the group is focused on this year.
