What causes intermittent heart pain?
Patient: Hello doctor, In mid-February 2011, had pacemaker/defibrillator placement for low EF @ 35% and irregular beats. For about two weeks I have had intermittent heart pain and pain on my left side at the level of the heart/breast. These pains do not occur at the same time. Could it be the device is lightly shocking? The pains almost feel like spasming. Heart rate and pulse are a.o.k. I am 57 year old female, 5 7 and weigh 175 Doctor: Madam you had undergone ICD and you must be under medications.You have chest pain or feel like shock , then you must consult your physician.To rule out CAD  or ice shocks , please get your ECG and device interrogation done as soon as possible.I don't think there is much to worry about.Take Care
