How well do TV medical dramas portray heart disease?

TV medical dramas often portray treatments for heart attacks and cardiac arrest. While the timelines are often accelerated and certain aspects may be dramatized to engage viewers, the medical details are, for the most part, factual and authentic. Writers and producers routinely rely on health care experts — including Harvard doctors — to make sure the information is accurate. For people with heart disease, seeing how emergency physicians treat urgent conditions may show them what to expect.
