When a patient asks too many questions and concerns, some drs. seem to treat her like a hypochondriac; when she downplays symptoms, she may be seen as in denial. I guess both dr and patient are walking a fine line.

this is only the second time I've met with Dr. Wozniak in the past several years. He showed a tremendous ability to communicate the root of the problem that is leading to the ablation procedure and was very descriptive as to what the procedure entails. He was also very communicative on this course of treatment versus other courses of treatment such as medicine or the lack of benefit of the thinning of the ventricular wall where my hypertrophy is located.
