Anyone here with ECG EKG knowledge?
I would like to find out peoples opinions on cardiomyopathy's in particular. And how they result in isoline changes on the ECG EKG.
I was having a debate with somebody recently, they protested that cardiomyopathy's (mainly chamber enlarging one's such as hypertrophic cardiomyopathy, arvc, dilated cardiomyopathy) have a false negative rate of around 30%!
I disagreed with them. If your heart muscle is truly enlarged, the electrical activity WILL be intercepted and therefore produce changes. Let's say athletic heart syndrome, if you detrain over 3-6 months then the heart will shrink somewhat and the ECG manifestations will vanish. But this isn't an overnight thing. That's why I can't understand how cardiomyopathy could be missed.
