“…11 Nevertheless, understanding the pattern of changes in hs-cTnT is crucial for differentiating between enzyme elevation in AMI and that related to ischemic myocardial injury from PSVT. Although multiple authors of case reports and series have shown that cardiac enzyme levels rise during PSVT, 7,12,13 we found only one study 14 in which the pattern of enzyme elevation was described. Of note, elevated concentrations of serum cTnT are observed in many but not all patients with PSVT, 8 rendering it difficult to explain the mechanism of cTnT elevation.…”

We studied the predictors and patterns of high-sensitivity cardiac troponin T (hs-cTnT) C ardiac troponin T (cTnT) is a highly sensitive and specific biomarker for the diagnosis of acute myocardial infarction (AMI).1 However, elevated cTnT is also seen in other cardiac and noncardiac conditions. 2-5 It has therefore been proposed that the diagnosis of AMI should be made depending on changes in cTnT level in an appropriate clinical situation, to distinguish ischemic from nonischemic causes of cTnT elevation. 6 In addition, recently available high-sensitivity troponin assays can reliably detect much lower concentrations of troponin than older assays could. However, minor changes or elevations in cTnT levels without other evidence for AMI can be confusing.Paroxysmal supraventricular tachycardia (PSVT) has been identified as a probable cause of troponin elevation in the absence of severe ischemic heart disease (IHD). 7,8 This can mislead clinicians in the management of PSVT. Therefore, defining the kinetic effects of troponin elevation, especially high-sensitivity troponin, as well as the predictors of elevation, is important for straightforward clinical diagnosis of a possible underlying ischemic condition.In this study, we had 2 goals: to identify predictors of high-sensitivity cardiac troponin T (hs-cTnT) elevation; and to determine the pattern of changes in hs-cTnT levels in PSVT patients who had elevated hs-cTnT levels (with or without IHD) upon presentation at the emergency department of our tertiary-care cardiovascular center. Patients and MethodsDuring calendar year 2013, we prospectively enrolled consecutive patients (age, >30 yr) who were admitted to the emergency department

“…Elevated levels of high-sensitive troponin and atrial natriuretic peptide (ANP) at SVT are well known (18)(19)(20). We did not consider troponin, but increased levels of ANP is strongly related to frequent urination after the onset of SVT, particularly in the presence of longstanding episodes.…”

Objective: Although electrophysiological study (EPS) is one of the most useful diagnostic approaches to detect the cardiac origin of palpitations, there is no clear indication for EPS in patients with palpitation in the absence of documented supraventricular tachycardia (SVT). In this study, we aimed to create a new SVT score model to detect the requirement of EPS in patients with palpitation without documented tachycardia. Methods: A total of 154 patients with palpitation were included in this study. To create the SVT score, we considered four main criteria with their subunits. They were severity, frequency, duration, and termination of the symptoms. EPS was performed on all the patients after their scoring assessment. Results: Median SVT score of induced tachycardia and non-induced patients was determined as 10 and 6 points, respectively; and it was found to be statistically significant; p<0.001. The cut-off value for inducibility was found to be 7.5 points through receiver operating characteristic curve analysis, (94.9% sensitivity, 92.1% specificity), and the area under the curve was determined to be 97.2 (94.8-99.5, p<0.001). Conclusion:According to our new SVT score model, ≥8 points strongly correlates with the inducibility of SVT during EPS.

“…In a study by Reichilin et al (1), the highest level of hscTnT was reported in the ACS group. However, troponin elevation could be also observed in noncoronary conditions, such as heart failure, pulmonary thromboembolism, pulmonary arterial hypertension, stroke, sepsis, acute aortic dissection, acute myopericarditis, hypovolemia, myocardial contusion, Takotsubo cardiomyopathy, and tachycardia; it might even represent a major diagnostic challenge to clinicians (14)(15)(16)(17)(18)(19).…”
