1.2a Telemetry Flashcards
Should continuous telemetry monitoring be used in cardiac rehabilitation? Why or why not?
No, the continuous use of telemetry monitoring in cardiac rehab programs has not been shown to reduce or prevent adverse events or sudden cardiac death.
Are exercise-related adverse event rates within cardiac rehab relatively high or low?
extremely low; one cardiac event for every 8484 exercise tests performed
When does the Saskatoon Cardiac Rehab program use telemetry?
on first day to establish baseline and compare this against previous ECGs
when “clinically warranted” from then on
What is different between continuous EKC monitoring versus intermittent monitoring?
continuous: by hardwire or telemetry
intermittent: quick look defibrillation paddles or periodic EKG strips
Where are the 3 leads placed for telemtry?
White (RA) - just below the right clavicle
Black (LA) - just below the left clavicle
Red (LL) - placed on non-muscular surface on the lower edge of the left rib cage
What is the saying used for the 3-lead placement?
“White on the right, smoke over fire”
What steps are necessary for skin preparation prior to placing the electrodes for telemetry?
Shave/cut hair from electrode sites
clean each site thoroughly with soap and water, a non-alcoholic wipe, or alcohol swab to improve electrical flow
dry the skin vigorously to increase capillary blood flow to the tissues
use an ECG skin prep pad or paper / sandpaper (removing part of the stratum corneum to allow electrical signals to travel to the electrode and scratch the stratum granulosum (epidermis middle layer) to reduce motion artifact)
