My husband was advised to get a defibrillator because his dilated cardiomyopathy has not improved much since March until now. He takes
Metoprolol, Perindopril and Spironolactone. His ejection fraction measured by MRI was 22% in March and now it is 25%. He has no symptoms.
While we all know that the defibrillator saves lives, I read that every electrical shock, whether warranted or not, will further weaken the heart, leading to a higher and faster mortality.
