AIVR = accelerated idioventricular rhythm

Submitted by Dr A Röschl on Sun, 05/28/2023 - 02:21

This Holter-ECG comes from a 70-year-old physician with coronary artery disease. He is twelve months after PCI (RCA, RCX). Currently no symptoms (no dyspnea, no chestpain, no palpitations). You can see that an overview/section from a Holter- EKG, 3 channels are shown, strip width is 30 seconds. First you can see a sinus rhythm with frequent PVCs, then there is a transition to an Accelerated idioVentricular rhythm (AIVR) that lasts almost a minute in total.

Submitted by Dr A Röschl on Sat, 05/27/2023 - 01:35

This ECG is from an 80-year-old lady who has collapsed or had sycopal episodes several times. The ECG comes from a Holter monitor. She has arterial hypertension and coronary artery disease. The ECG shows a second-degree, Mobitz Type II AV block. In both types of AVB, the PP intervals are usually the same.

LBBB

Submitted by Dr A Röschl on Sat, 05/27/2023 - 01:16

Here is the EKG of a 54 -year -old woman without known cardiac disease. The EKG was routinely carried out before a surgical intervention. It`s a screenshot. You can see a normal SR with narrow QRS, followed by an incompete LBBB and then a complete LBBB. A LBBB is often associated with cardiac diseases, but it also occurs without a heart disease. At the moment i can`t upload the files with high resolution. You can download (in German: herunterladen) the image with high resolution here: https://magentacloud.de/s/ciY24ZZ8e32wQiX

Do You Teach ECG or Cardiology Classes?

Submitted by Dawn on Mon, 06/11/2018 - 16:12

This ECG Guru website exists for the purpose of sharing teaching resources with anyone who teaches ECG or Cardiology classes.  It can be difficult to find non-copyrighted and free images to use in presentations.  Often, those resources that are available are too small to reproduce well for a handout or projector.  Our website seeks to fill this gap to make it easier for more people all over the world to receive ECG education.

Basics of ECG Rhythm Diagnosis Videos From Dr. Ken Grauer, M.D.

Submitted by Dawn on Tue, 06/23/2015 - 14:19

Those of you who have followed the ECG Guru for a while are very familiar with the work of Dr. Ken Grauer, M.D.  He is a generous contributer to the ECG Guru website, and functions as our official Consulting Expert.  He has published many books and e-publications which are (in our opinion) some of the BEST ECG references available, and he has worked hard to keep them low priced to make them available to all of us.  He also offers seemingly endless ECG knowledge and insights for FREE, via this website, his own website, and social media.

Are You New to Laddergrams?

Submitted by Dawn on Fri, 02/20/2015 - 21:34

A laddergram is a diagram of conduction through the heart, presented in a minimum of three tiers, one for the atria, one for the AV junction, and one for the ventricles.  Laddergrams are very useful for presenting and testing your theory of a dysrhythmia.  Instructors often use them to illustrate complex dysrhythmia mechanisms.
