Dr. Alejandro Borquez is a pediatric and congenital electrophysiologist at Rady Children's Hospital-San Diego and an assistant clinical professor at UC San Diego School of Medicine. He earned his undergraduate degree at Dartmouth College and his medical degree at the University of California, Davis School of Medicine. After completing a residency in pediatrics at Stanford, he returned home to the San Diego/Tijuana region to complete a fellowship in pediatric cardiology at Rady Children's Hospital/UC San Diego. He then stayed on to complete an advanced fellowship in pediatric and congenital electrophysiology.

Dr. Borquez specializes in the diagnosis and management of cardiac rhythm disturbances from fetal to adult life, including advanced monitoring and diagnostic techniques, antiarrhythmic medications, catheter-based therapies for arrhythmias, heritable arrhythmia syndromes, rhythm disturbances associated with congenital heart disease, as well as pacemaker and ICD implantation. His research interests include the study of novel antiarrhythmic medications and implantable devices. He is actively involved in mentoring and teaching medical students, residents and fellows in pediatric cardiology.

Outside of medicine, Dr. Borquez enjoys hiking, surfing and cooking for his friends and family.
