So it's 7yrs, while radiology is 6yrs. I bet I could get my Im->cards residency in a nice geographical area, unlike rads where I'd have to go wherever they take me. And supposedly radiologists have trouble finding work after residency and have to move to undesirable parts of the country. What makes you think that cards work more after residency? I understand they have to split night call and may have to do stents at night. But it is obviously a shared call. But during most days they supposedly do most of their work outpatient, like ekg, echo, PAD ultrasound, listening to murmurs) That does not seem so exhausting or stressful.
My other interest is ER. Only 3yrs, right. But I am afraid that might be a stressful job and I might feel incompetent, I mean they have to call consults all the time, while a cardiologist or radiologist is THE consultant.
