While on the higher end, these starting salaries are not at all unheard of for a non-interventional/EP cardiologist. As mentioned before, echo and SPECT still pay fairly well and can be done in high volumes. Cardiac CT is continuing to take off; many larger practices own a multislice CT scanner. Also, many non-invasive cardiologists are also trained in peripheral vascular ultrasound. Finally, some non-EP cardiologists implant devices. This is all on top of the fees for a consultation, and there is NEVER a shortage of patients who require a cardiovascular consultation.
I would point out that cardiologists who are in these higher income brackets work their a$$es to make this income. As with every medical field, higher salaries tend to be seen in more remote areas with small but extremely busy practices and good payer mixes. Many of us choose to accept a more moderate salary to live in a more cosmopolitan area, have less call or be in a larger group that allows one to occupy a particular professional niche. When you see a high starting salary, look carefully at the particulars of the job.
