Study Notes
EKG Lead Placement
- Lead V4 is correctly placed at the 5th intercostal space along the midclavicular line.
- For a 5-lead EKG, the red lead is positioned at the lower left torso.
- Lead V5 should be placed at the anterior axillary line in the 5th intercostal space.
Cardiac Rate Calculation
- An R-R interval that spans five large boxes corresponds to a heart rate of 60 beats per minute.
Pediatric EKG Procedures
- When performing an EKG on a young child, it's important to explain that the procedure won't hurt, rather than restraining the child or asking parents to leave.
Respiratory Variation
- Variations in vagal tone associated with changes in the respiratory cycle indicate sinus arrhythmia.
Infant Pulse Measurement
- The most appropriate site for measuring the pulse of an infant is the brachial artery.
Symptoms During Stress Testing
- Chest heaviness and diaphoresis in a patient during a stress test may signal a myocardial infarction.
EKG Standardization
- To create an EKG standardization mark of 5/mm, a sensitive setting of 1/2 is required.
Concerns During Cardiac Stress Tests
- A decreased heart rate during stress testing is a concerning sign for the EKG technician.
Equipment Repairs
- EKG machine repairs should be conducted by a biomedical technologist.
Holter Monitor Instructions
- Patients should push the event button on a Holter monitor if they experience discomfort to accurately capture relevant data.
Patient Preparation for Telemetry
- Prior to telemetry monitoring, patients may clean their skin with an alcohol pad for electrode application.
Body Temperature Measurement
- The most accurate site for measuring body temperature is the rectum.
Myocardial Infarction Detection
- The presence of pathological Q waves on an EKG tracing is indicative of a myocardial infarction.
Sinus Arrhythmia Triggers in Children
- Sinus arrhythmia in children can be caused by their respiration patterns.
