Final answer:
Health Level 7 (HL7) is the international organization responsible for developing data standards for medical devices like pacemakers and insulin pumps.
Step-by-step explanation:
The organization responsible for data standards applicable to medical devices such as pacemakers or insulin pumps is Health Level 7 (HL7). This international organization develops standards for the exchange, integration, sharing, and retrieval of electronic health information that supports clinical practice and the management, delivery, and evaluation of health services.
Devices like pacemakers and insulin pumps require a high level of interoperability with other healthcare systems, hence the importance of following HL7 standards.
