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.
