Biography

Andrew D. Beaser, MD is a cardiac electrophysiologist specializing in the diagnosis and treatment of complex heart rhythm disorders. He has extensive expertise in catheter ablation techniques for arrhythmias, including atrial fibrillation (AF), supraventricular tachycardia (SVT), and ventricular tachycardia (VT), employing advanced technologies such as radiofrequency (RF) and pulsed field ablation (PFA). Dr. Beaser is also skilled in device-based therapies, performing procedures including pacemaker and defibrillator implantations, transvenous and subcutaneous ICDs, and leadless pacemakers. His work in lead management has established him as a leader in complex laser lead extraction procedures. In addition to clinical practice, Dr. Beaser engages in research that aligns with his subspecialty interests, aiming to enhance the safety and effectiveness of lead extraction and investigating the impact of GLP-1–based weight-loss therapies on the burden of AF. He actively participates in multidisciplinary care at the Hypertrophic Cardiomyopathy Center and provides consultative cardiovascular care to athletes, including the Chicago Sky WNBA team and collegiate programs. Dr. Beaser is a dedicated educator and is passionate about teaching the principles of cardiac electrophysiology and ECG interpretation to trainees.
