Location-based services

An external device for communication with an implantable device, the external device comprising:

• a communication circuit configured to receive a communication signal from at least one other device different from the implantable device, wherein the communication circuit is configured to receive a first communication signal, a second communication signal, and a third communication signal;
• a locating circuit configured to determine a location of the external device using the received communication signals;
• a control circuit electrically coupled to the communication circuit and the locating circuit,
• in response to receiving the first communication signal, the locating circuit configured to determine that the location is a first location;
• in response to receiving the second communication signal, the locating circuit configured to determine that the location is an operating room, an emergency room, or a magnetic resonance imaging (MRI) clinic;
• in response to receiving the third communication signal, the locating circuit configured to determine that the location is a general practice clinic;
• in response to the locating circuit determining that the location is the general practice clinic, the control circuit configured to provide read-only access to the implantable device;
• in response to the locating circuit determining that the location is the operating room, the emergency room, or the MRI clinic, the control circuit configured to provide access to turn at least one of tachyarrhythmia detection and cardioversion/defibrillation therapy on and off;
• and
• in response to the locating circuit determining that the location is the first location, the control circuit configured to provide access to all programmable device parameters;
• wherein the first location is at least one of
• a cardiology clinic, and
• an electrophysiology clinic.
