The Arrhythmia Clinic Team: Who are we? At our clinic we take a comprehensive and multidisciplinary approach to managing arrhythmias.  Under the leadership of Dr. Dan Alyesh, our team includes nurse practitioners, cardiac RNs, LPNs, medical assistants, and schedulers who work collaboratively to implement a patient-centered, integrated, multifaceted care plan.   

Your initial visit will include a comprehensive cardiac evaluation and consultation with an experienced nurse practitioner who will then recommend the best-suited cardiologist for you to meet with after any outstanding cardiac testing is completed.  The rest of your comprehensive arrhythmia management plan will be facilitated by our dedicated Arrhythmia Clinic team.  Your visits will be conducted by a nurse in collaboration with a nurse practitioner.  All clinic visits will be reviewed and overseen by an electrophysiologist; a cardiologist specialized in the heart’s electrical system.  Once your heart rhythm is effectively managed, you will be transitioned out of Arrhythmia Clinic and into the care of the cardiologist that will see you routinely thereafter.
