I am recently recuperating from takotsubo cardiomyopathy, an illnesss that mimmics a heart attack, but is believed to have nothing to do with blocked arteries.  The heart muscle walls are affected, ususally left ventricle, with varying differences in the T and Q waves shown on the ECG.  This illness was discovered in the early 1990's in Japan.  Its name means broken heart or octopus and is referred to octopus traps. I was hospitalized twice within the past three weeks and am on day no. 6 at home.  This illness is due to the heart producing toxins, too much adrenaline/norepinepherine, which in turn damages the heart muscle and is stress related.  Most patients recover 100% although there can be recurrence within the first four years.  It can take several months to recover.  I have learned quite a lot online.  Exercise has become a part of my daily regiment.  The guidelines for treatment include low salt and sugar diet.
