Summer Break

Submitted by Dawn on Sat, 06/15/2013 - 21:01

You may have noticed that Dawn's contributions have not been strictly weekly as of late.  My apologies, but we have been in the process of moving 800 miles from Florida, USA to Tennessee, USA.  For our family, this involves moving quite a few pets.  Tommy the pony went first, and is now in Tennessee.  We are about to move the rest of our pets and all of our belongings.  This is a time and energy-consuming undertaking which has been complicated by several adventures, the worst of which is the demise of the family car!

Jason's Blog: ECG Challenge for the month of June, 2013.

Submitted by jer5150 on Mon, 05/27/2013 - 11:40

Unfortunately, I have no available clinical data on this patient.  Merely looking for an interpretation of the ECG in it's raw form.

Must See: Video Presentation by Dr. K Wang on Dr. Smith's ECG Blog

Submitted by Dawn on Fri, 05/10/2013 - 10:22

 Dr. Smith, on his ECG Blog, has posted a must-see video presentation by famous ECG guru, Dr. K. Wang, discussing how helpful PVCs can be.  Dr. Smith's blog is one of the best out there for ECG fans, and Dr. Wang is a wonderful teacher.  The ECG Guru highly recommends both.

Jason's Blog: ECG Challenge April and May, 2013.

Submitted by jer5150 on Sun, 04/21/2013 - 13:30

Jason is taking a break (everyone needs one now and then).  April's ECG will appear through May, as well.  It's a good one!

Finally, someone addresses the pervasive problem of fake ECG images!

Submitted by Dawn on Wed, 04/10/2013 - 17:18

Ever since I first had a vague idea of what an ECG is, and looks like, I have noticed that graphics artists ALMOST NEVER get it right when using ECGs in advertising.  Especially bothersome to me is when the graphic representation of an ECG is on the side of an ambulance, rescue vehicle, or hospital! Up until now, it has bothered me to no end, but today I found Drew Rinella's hillarious blog, "Stupid Heart Rhythms".

Jason's Blog: ECG Challenge of the Week for April 7th - 14th.

Submitted by jer5150 on Sat, 04/06/2013 - 12:18

At this time of posting, I currently have no clinical data for this patient.  This ECG is of interest because of its arrhythmic and nonarrhythmic elements. 

I can think of at least two possible explanations for the mechanism of this rhythm and both would benefit from being illustrated by a laddergram. 

One mechanism is rather exotic and has not been previously seen here on this website or discussed in the various FB forums.

Jason's Blog: ECG Challenge of the Week for March 31st - April 7th.

Submitted by jer5150 on Sun, 03/31/2013 - 13:08

Patient's clinical data:  66-year-old white man.

Amongst the computer's several statements was the interpretation of "Undetermined rhythm".  To the computer's statement, the reviewing cardiologist added the freehand text of "Abnormally slow" but failed to provide a diagnosis.   

What is accounting for this pattern?

Takotsubo Cardiomyopathy Ventriculogram

Submitted by Dawn on Sun, 03/24/2013 - 14:30

This ventriculogram shows the typical apical ballooning of the left ventricle during Takotsubo myocardiopathy.  This serious condition can be caused by extreme stress, such as in the death of a loved one, or prolonged high stress levels.  The ECG will usually show ST elevations indicating an anterior wall M.I., but the angiogram will show no arterial occlusions.  Takotsubo myopathy causes a sudden onset of congestive heart failure.  It is transient, and those who survive it generally recover fully.  For an excellent and complete discussion of Broken-Heart Syndrome,

Patient's clinical data:  47-year-old black man.  Another serial ECG (seen below) showed a supraventricular tachycardia (SVT) at a rate of 164/min that was diagnosed by an Electrophysiologist as atrioventricular nodal reentrant tachycardia (AVNRT).  How does knowing the mechanism of AVNRT help you in determining the nature of the mechanism in this week's ECG.

Using Ventriculograms to Enhance Your ECG Classes

Submitted by Dawn on Mon, 03/18/2013 - 14:10

The ECG Guru now has a You Tube site where you can find videos to enhance your classes.  As with all ECG Guru content, there is no charge and no copyright.  Ventriculograms are often obtained during a cardiac cath procedure. A curved, or pigtail, catheter is inserted through the arterial access line into the aorta and then the left ventricle.  Contrast is introduced into the left ventricle and the pumping function of the ventricle can be observed.  The structure and function of the aorta and mitral valve may also be observed during this procedure.
