Programs & Conditions


Dr. Makielski 's research has been continuously funded by the NIH since 1985 and he is a leader in ion channels research employing molecular biological and electrophysiological methods. His interests include the genetic basis of arrhythmia, such as the Burgada syndrome and long QT syndrome, with a focus on the cardiac sodium channel. Dr. Makielski is also studying the ATP-dependent potassium channel and its role in ischemia and ischemic preconditioning in the heart.
