Describe a pacemaker code - correct answer...The standardized code consists of up to 5 letters- 1st letter- identifies which chamber(s) of the heart are paced by the pacemaker- "A" refers to atrium, "V" to ventricle, and "D" to both atrium and ventricle (also called "dual") ***There are many types of permanent pacemakers available. To facilitate and standardize communication about the types of pacemakers and pacemaker functions, a standardized coding system was developed through ...

MRSO Exam Questions and Answers Latest Updated 2024 (GRADED A+) MR Safety Officer responsibilities - Answer The role of MRSO is often carried out by the senior Radiographer (in the USA this will generally be an MR technologist), but other suitably trained individuals could also fill this role. Multiple MRSOs could be appointed, provided only one is in charge at a given time. His/her responsibilities include the following: To be readily accessible and available (eg, to the operators of the ...

Pacemakers of the Heart correct answer: Sinoatrial (SA) node Atrioventricular (AV) node Bundle of His Bundle Branches Purkinje Fibers -SA node: p wave -SA node to AV node: PR segment -Impulse travels from Bundle of His to Bundle branches and then to Purkinje fibers: QRS complex -Repolarization of ventricles: T wave P wave correct answer: sinoatrial node (SA node) starts an impulse, as the wave of depolarization spreads through the atria, _______ is inscribed on the ECG AV nod...
