Yes, very fast heart rates from svt can potentially cause small elevations in troponin that are not necessarily of concern particularly in the setting of normal cardiac testing otherwise. who should i see next. MyHeart is not a substitute for advice from a doctor. One proposed mechanism for this phenomenon is that there is disrupted autonomic function after a cerebrovascular accident (CVA), which can cause an increased catecholamine response that acts on the cardiac myocytes.
