ECG: Laboratory Experiment Example ( J. Fickas, A&PII)


1. Make sure the EGC unit is plugged in and turned on and wait for a standard

menu to display as shown on slide page 4.

2. Press button 7 (LEAD) until the screen displays “Lead II”

3. Press button 6 (FORM) until the screen displays “3ch + 1Rhy”

4. Place sticky tabs (attach pads) on each limb at/near the locations shown

on the diagram and then attach limb leads.

- Limb leads are marked (RA – right arm etc. )

5. While sitting very still, press the 0 (RECORD) button to begin the reading

session. The reading is done and then processed before it prints.

6. Calculate your HR from the reading printout using the information and table in

your lab instructions (worksheet on next slide).

Measurement

# of mm between the “R” peaks of two consecutive QRS complexes

= ______________ sec x 25 mm/sec x 60 sec/min

= ______________ beats/min (each tiny square within the larger square is a mm)

The heart rate (HR) is the number of beats the heart makes in one minute.

The average heart rate is 72 beats/minute.

Stroke Volume (SV) is the amount of blood ejected from the heart in one beat.

The average stroke volume is 70 ml.

Cardiac Output (CO) is the amount of blood ejected by the heart in one minute.

CO can be found by the following equation: CO = HR x SV

Using the average SV, calculate your CO at rest: _____________________________

Now calculate your CO after running the stairs: _____________________________

ECG; CardioCare 2000 Features


The CardioCare 2000; 12 channel resting ECG suitable for use in private practice, ER, or hospital use.

Designed for maximum ease of use and convenience. Software upgradeable and networkable.

Simultaneous 12 Channel Resting ECG; Acquires 10 full seconds of ECG data simultaneously from 10 leads

to produce an accurate 12 channel printout with analysis in under 60 seconds!

ECG Interpretation Program; Over 80 kinds of interpretation results based on the advanced Minnesota Code

are provided to aid your diagnosis. The interpretation algorithms are expanded with regular software updates.

A4 Full Size Paper ; in 1,3,6 and 12ch formats. Full size print-outs improve readability and make for easier

filing in the patient chart. A convenient Copy button lets you generate ECG copies in any of the available

formats.

Low Maintenance Cost; uses normal fax paper which costs about ¼ the cost of ECG paper. It will even

generate it's own grid!

ECG: Background Info; Typical Leads Placement


ECG: Background Info; Wave Basics


P wave: the sequential activation (depolarization) of the right and left atria

QRS complex: right and left ventricular depolarization (normally the ventricles are activated simultaneously)

ST-T wave: ventricular repolarization

U wave: origin for this wave is not clear - but probably represents "afterdepolarizations" in the ventricles

PR interval: interval onset of atrial depolarization (P wave) to onset of ventricular depolarization (QRS complex)

QRS duration: duration of ventricular muscle depolarization

QT interval: duration of ventricular depolarization and repolarization

RR interval: duration of ventricular cardiac cycle (an indicator of ventricular rate)

PP interval: duration of atrial cycle (an indicator of atrial rate)
