My husband has been told he has ventricular tachycardia and supra ventricular tachycardia. A cardiac electrophysiologist wanted to do an ablation, but could not get the heart to react in order to map the electrical impulses. Since the EP study, he has had increased episodes of tachycardia and several episodes where he has passed out while walking. Dr does not seemed overly concerned and wants him to wear a heart monitor for two weeks, something he did earlier in the year to get the tachycardia diagnosis. I feel frustrated by physicians apparent lack of concern.
