Patient Testing
Patient Recommendations
The following patient factors may affect the accuracy of the MyoVista Device results and should be
considered by the medical professional when interpreting test results:
• Caffeine consumption within 2 hours prior to testing .
1
• Smoking or using Nicotine replacement therapy .
2, 3
• Significant alcohol consumption on the previous day .
4
• Phlebotomy within 20 minutes prior to testing .
5
• Patients who are not in a horizontal position with a resting heart rate during testing .
5
• Patient movement during testing .

Patient Condition and History
Certain medications can affect test results . Examples include medications taken for heart disease,
hypertension, diabetes (including beta-blockers), digitalis, dobutamine, amildarone, and narcotics .
Prior to testing, review the patient’s history of health issues and medications .
Electrode Placement
The MyoVista electrode placement protocol is aligned with the standard AHA or IEC 12-lead ECG
electrode placement protocol .
Lead misplacement can cause misinterpretation of an ECG and result in the wrong diagnosis,
delaying or prompting poor treatment recommendations that could be harmful to the patient .
Some of the most common lead placement mistakes are 1) limb lead reversal and 2) Incorrect lead
placement . Special attention must be given to placing leads at the correct anatomical landmarks
while recognizing other soft tissue considerations . Being able to recognize misplacement errors will
help to reduce inaccurate testing results .
Attaching Electrodes to the Patient
To obtain adequate signals, connect electrode connectors and electrodes firmly . For instructions
about proper placement of electrodes on the patient, see “Electrode Placement” on page 37 .
Caution: To avoid tension on the electrodes, allow sufficient slack in patient cable.
Caution: Electrodes placed on sites with excessive body hair, prior surgical sites, scars, or
over implanted devices may impact test results.
Caution: Clothing or tissue causing improper placement of electrodes may impact test accuracy.
1 . Prepare the skin appropriately for good electrode adhesion and conduction . To ensure optimal
electrode adhesion and conductivity, shave excessive body hair .
2 . Peel the electrodes from the protective sheet .
3 . Place the electrodes on the skin surface (see “Electrode Placement” on page 38) .
