Since some of these threads discuss fiscal motives, I thought you might be interested in the contrast between two frequently discussed EP's: Sanjiv Narayan (FIRM ablation) and Andrea Natale (Maestro).
The source of this is OpenPaymentsData. As that site explains:

Sometimes, doctors and hospitals have financial relationships with health care manufacturing companies. Open Payments is the federally run transparency program that collects information about these financial relationships and makes it available to you. These relationships can involve money for research activities, gifts, speaking fees, meals, or travel. One of the ways we provide this data to the public is through this search tool, which allows you to search for a doctor, teaching hospital, or company that has made payments. Exploring this information, and discussing the results you find with your healthcare provider, can help you make more informed healthcare decisions.
It's actually interesting data, with a line item for each payment.
The link for Dr. Narayan (2014) shows he received $10,981,153.04 in 48 transactions, where most are very small (meal reimbursements, etc), but one is $10,964,988.77, from Topera (his FIRM company).
The link for Dr. Natale (2014) shows he received about 100x less ($90,280.12 in 127 transactions, mainly meal reimbursements and small consulting fees.
It's kind of interesting to look up MD's whom one has interacted with, to see if their recommendations have any connection to their OpenPaymentsData line items.
