rule of thumb. an increase or decrease will cause arrhythmias. increase will increase bp and a decrease will decrease bp

I don't think there is an easy way to remember each one.

Hypocalcemia- Prolonged ST and QT intervals

Hypercalcemia- shortened ST segment

- widened T wave

Hypokalemia- ST depression

- shallow, flat, inverted T wave

- Prominent U wave

Hyperkalemia- Tall, peaked T waves

- Flat P waves

- widened QRS complex

- Prolonged PR interval

Hypomagnesemia- Tall T waves

- Depressed ST segment

Hypermagnesemia- Prolonged PR interval

- widened QRS complexes

thought this might help...i dont know of any shortcuts though... :)

If you go further and make a table, You'll see some similarities and differences and I hope it'll help to remember.:wink2:

I BELIEVE THE BEST WAY TO REMEMBER IS TO UNDERSTAND WHY THE CHANGES OCCUR AND SEEING EXAMPLES. i HAVE A TEACHING WEB SITE WHICH CONTAINS A POWER POINT PRESENTATION ON BASIC EKG AND EARLY IN THE PROGRAM IS AN INTERNAL LINK TO ELECTROLYTE INDUCED EKG CHANGES. i HAVE USED THE programs TO TEACH NURSING AND MEDICAL STUDENTS. tHE SITE ALSO HAS AUSCULTATION PROGRAMS AND A SELF TEACHING VIRTUAL PEDIATRIC PATIENT

This for anyones use. I would appreciate feed back as to its usefulness and suggestions as I am constantly trying to improve the site.

hi! hope this will help you...

first, think of the normal ECG first...i made a poster that's really big and put it in my wall so i can see it always...

think how it starts and end...so it starts with P followed by Q R S T

so let's start from where it begins...

P flat

this was excellent. many thanks.

however, i'm still struggling with trying to understand why a certain electrolyte imbalance would cause the changes that it does. can someone provide an actual explanation of why the ecg changes happen? for example, since qrs represents ventricular depolarization, why would potassium excess cause a widened qrs?
