p.s.
references made to 'counselor' make me wonder about the true credentials or lack of them of that person. If your Son is not seeing a Psychiatrist (who is also an M.D. as psychiatrists must be) then he is in the hands of what I would call a quack. If he is having medication related symptoms, he needs a medical doctor who also can correctly recognize/diagnose any existing mental disorders - which I personally doubt your Son has - not a 'counselor', IMO.
I am not a doctor, but I would seriously be considering that the Concerta is the source of the problems. Here are a few links to info on that, in case you've not already found time to do that kind of research?
http://en.wikipedia.org/wiki/Methylphenidate
especially see the contraindications part:
"Methylphenidate should not be prescribed concomitantly with tricyclic antidepressants, such as desipramine, or monoamine oxidase inhibitors, such as phenelzine or tranylcypromine, as methylphenidate may dangerously increase plasma concentrations, leading to potential toxic reactions (mainly, cardiovascular effects). Methylphenidate should not be prescribed to patients who suffer from severe arrhythmia, hypertension or liver damage. It shouldn't be prescribed to patients who demonstrate drug-seeking behaviour, pronounced agitation or nervousness.[35] Care should be taken while prescribing methylphenidate to children with a family history of Paroxysmal Supraventricular Tachycardia (PSVT)."
I have no idea if he already has a tendency toward tachycardia or arrhythmia but in the list of side effects also on that reference, tach is listed. IMO, any drug that can cause or exacerbate cardiac problems should not be given to someone with pre-existing cardiac problems. Who actually prescribed that, the 'counselor' or an MD?
OMG read this too:

Serious Cardiovascular Events
Sudden Death and Pre-existing Structural Cardiac Abnormalities or Other Serious Heart Problems
Children and Adolescents
Sudden death has been reported in association with CNS stimulant treatment at usual doses in children and adolescents with structural cardiac abnormalities or other serious heart problems. Although some serious heart problems alone carry an increased risk of sudden death, stimulant products generally should not be used in children or adolescents with known serious structural cardiac abnormalities, cardiomyopathy, serious heart rhythm abnormalities, or other serious cardiac problems that may place them at increased vulnerability to the sympathomimetic effects of a stimulant drug.
Adults
Sudden deaths, stroke, and myocardial infarction have been reported in adults taking stimulant drugs at usual doses for ADHD. Although the role of stimulants in these adult cases is also unknown, adults have a greater likelihood than children of having serious structural cardiac abnormalities, cardiomyopathy, serious heart rhythm abnormalities, coronary artery disease, or other serious cardiac problems. Adults with such abnormalities should also generally not be treated with stimulant drugs.
Hypertension and other Cardiovascular Conditions
Stimulant medications cause a modest increase in average blood pressure (about 2 to 4 mmHg) and average heart rate (about 3 to 6 bpm) [see Adverse Reactions (6.5)], and individuals may have larger increases. While the mean changes alone would not be expected to have short-term consequences, all patients should be monitored for larger changes in heart rate and blood pressure. Caution is indicated in treating patients whose underlying medical conditions might be compromised by increases in blood pressure or heart rate, e.g., those with pre-existing hypertension, heart failure, recent myocardial infarction, or ventricular arrhythmia.
Assessing Cardiovascular Status in Patients being Treated with Stimulant Medications
Children, adolescents, or adults who are being considered for treatment with stimulant medications, should have a careful history (including assessment for a family history of sudden death or ventricular arrhythmia) and physical exam to assess for the presence of cardiac disease, and should receive further cardiac evaluation if findings suggest such disease (e.g., electrocardiogram and echocardiogram). Patients who develop symptoms such as exertional chest pain, unexplained syncope, or other symptoms suggestive of cardiac disease during stimulant treatment should undergo a prompt cardiac evaluation."
