This Dr. is top notch. I am a new patient moving in from another state. Dr. Marcus spent nearly 1 hour in the first visit and asked important questions that no other cardiologist had ever asked He put me on a heart monitor for 1 month. Other Dr.s put me on a monitor for only 1 week. In the 3rd week the monitor triggered an alert for me to get to the hospital - my heart beat was 30. In the hospital it dropped to 20 beats and a pacemaker was installed. This man saved my life. Without his foresight I would not be here today to tell this story.
