R-R interval Ans: Represents the time between successive R waves.
U wave Ans: Appears after the T wave in some EKGs.
Bundle of His Ans: Part of the conduction system that transmits impulses from the AV
node to the bundle branches.

Somatic tremor Ans: An artifact likely present on the EKG of a patient with
Parkinson's disease.
HIPAA Ans: Health Insurance Portability and Accountability Act, which protects
patient privacy.
Telemetry monitoring Ans: Continuous monitoring of a patient's heart activity.
Electrodes from different manufacturers Ans: Should not be used on the same patient.
