The most common causes of artifacts originate from internal (physiological) and external (non-physiological) sources (Table 1 â). Artifacts created from these sources can simulate arrhythmias such as atrial flutter and ventricular tachycardia. 2.
Trusted Platform Module. Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, which is a dedicated microcontroller designed to secure hardware by integrating cryptographic keys into devices. TPM's technical specification was written by a computer industry consortium called Trusted Computing Group (TCG).
A TPM must also have an Endorsement Key (EK), which is permanent once set for that TPM. Other keys are derived from or signed by the EK. Every time the computer starts, certain measurements are made and stored in the TPM's platform control registers (PCRs). PCRs are discussed in more detail later in this chapter.
