Dear Dave,
Firstly, a holter monitor as you know does not always catch the pathology or problem so to speak, thus with the symptoms of dizziness/faintness that you have been experiencing, it probably would be smart to have an event monitor that would discern at the time of these said symptoms, what the rhythm is- is it the mild heart block or the tachycardia that is occurring? Also, in a patient without high degree heart block(which almost always requires a pacemaker) who has symptoms as you do, I would consider a drug for your high blood pressure that does not effect heart rate (as the tenormin does) just to see if I could prevent your symptoms- Heck why not consider these symptoms as a side effect of any of the drugs that you take ( for instance are the drugs lowering your blood pressure so much at certain times of the day that you are getting light headed and dizzi?) As you can see it would be very helpful to know what your blood pressure is during the symptoms.
For so young a person, it is quite unusual to have thickened heart walls, are you aware of all your echo findings (ultrasound of the heart?)
It is important that you discuss these issues with your physician, including the holter results, where to go from here/there, and any abnormal echo findings.
I hope this information is useful. Information provided in the heart forum is for
general purposes only. Only your physician can provided specific diagnoses and therapies.
Feel free to write back with further questions. Good luck!
