About me

Pronouns: He | Him | His

Dr. Daniel P. Morin is a cardiologist who specializes in electrophysiology (studying the electrical activity that controls the heart's rhythm). He cares for patients with a range of heart rhythm conditions, including those requiring devices, such as pacemakers and defibrillators, and those that benefit from advanced ablation procedures, such as atrial fibrillation and other abnormally fast rhythms. He directs UCSF's cardiac electrophysiology laboratory.

In his research, Morin is interested in a wide variety of heart conditions and treatments. He has investigated predictive factors in sudden cardiac arrest, new applications for cardiac resynchronization therapy (a treatment for heart failure), how the heart's ability to contract changes after an ablation procedure, and how to improve electrical cardioversion (shocking the heart to correct an irregular heartbeat). His research has been published in the New England Journal of Medicine, Journal of the American College of Cardiology, European Heart Journal and Heart Rhythm (the journal of the Heart Rhythm Society).

Morin earned his medical degree from the University of Massachusetts Chan Medical School and his Master of Public Health degree from the Harvard T. H. Chan School of Public Health. He completed a residency in internal medicine at Tufts Medical Center. At New York – Presbyterian/Weill Cornell Medical Center, he completed a fellowship in cardiovascular disease and a fellowship in cardiac electrophysiology.

In addition to caring for patients, Morin is dedicated to promoting cardiological research. He is deputy editor of Annals of Internal Medicine: Clinical Cases, and was the first online editor of Heart Rhythm, serving for five years. In addition, he is associate editor of several other medical journals and serves on the Heart Rhythm Society's board of trustees.

    Most excellent service

    Dr. Morin was highly knowledgable. He had gone over my charts before seeing me and after reading my notes from the other care providers he just wanted to hear from me and how I was feeling and doing. Dr. Morin focused 100% on me and my health issue. Thank you

    This was my first appointment with Dr. Morin, and I couldn't be more pleased! He had obviously read my entire history prior to my visit. He listened attentively, was truly caring, and provided me with not only excellent information, but also a great deal of comfort. A treasure! Also, a nurse named Anna was present. . . She also was very attentive and kind.

    Dr. Morrin showed a genuine interest in me by asking about my parents and offering condolence to the loss of my mother. He was concerned about my children's potential health problems passed on by heredity, so he will try to see why I have 3rd degree heart block. I was persuaded to get the pacemaker by his simple and yet profound explanation, illustration, and application of needing the pacemaker. I appreciated that Dr. Morrin had an ultrasound test and blood work done before the procedure to see if something else needs attention.

    I wish everyone could have a Dr like my Dr Moran he tells you the complicated things wrong with my heart in simple terms I could understand he drew my picture showed me exactly what was wrong how he would try to fix it. I had Dr just hand you paper say here's info to read call nurse if you have questions. Dr Moran went through my ekgs to Pet Scan told me in plain words what it showed. I told him I fully trust him in his skill and judgement & know he will try his best to make me better with the Ablation procedure. I was frightened but he quickly put me at ease.

    I was very terrified that my heart is giving me such horrible pain racing. In my chest so I throw up. Dr Moran made me feel so cared for that he will find a solution to cause of all this. I felt so calm relieved and in good trusting hands. He reassured me told me everything in a way I clearly understood. Constantly listening to me I appreciated that so much.
