[|Human|] my partner has a crtd fitted due to dilate cardiomyopathy causing left ventricular non compaction. hes had the device for almost 4 months but over the last week or so hes been getting a dull ache in his chest which at times has caused considerable discomfort. any ideas what might be causing this?
[|AI|]  Dear MadamThanks for your query. The dull ache, if transient, like a shock, can occur in such patients as a result of shock given by CRT-D device. These shocks may be appropriate or in appropriate which will be decided by pacemaker evaluation. If the dull ache is persistent but is precipitated by exertion, this could be anginal pain which may occur in late stages of DCMP. Persistent dull ache unrelated to exertion can occur due to very severe heart disease or can be non-cardiac. An evaluation by your cardiologist is required and will be helpful. SincerelySukhvinder
