“…Left ventricular function has been shown clinically to be transiently decreased after supraventricular tachycardia(s) or rapid pacing. [36][37][38] These types of change, in addition to a reduction in cardiac b adrenergic responsiveness, have been noted after as little as one hour of exercise, 35 39 as well as after the completion of an Ironman triathlon. 40 The reduced responsiveness to catechols also correlates closely with the degree of cardiac fatigue, as measured by a reduction in ejection fraction.…”

Background: Continued exposure to prolonged periods of intense exercise may unfavourably alter neuroendocrine, neuromuscular, and cardiovascular function. Objective: To examine the relation between quantifiable levels of exertion (TRIMPS) and resting heart rate (HR) and resting supine heart rate variability (HRV) in professional cyclists during a three week stage race. Method: Eight professional male cyclists (mean (SEM) age 27 (1) years, body mass 65.5 (2.3) kg, and maximum rate of oxygen consumption (V O 2 MAX) 75.6 (2.2) ml/kg/min) riding in the 2001 Vuelta a España were examined for resting HR and HRV on the mornings of day 0 (baseline), day 10 (first rest day), and day 17 (second rest day). The rest days followed stages 1-9 and 10-15 respectively. HR was recorded during each race stage, and total HR time was categorised into a modified, three phase TRIMPS schema. These phases were based on standardised physiological laboratory values obtained during previous V O 2 MAX testing, where HR time in each phase (phase I = light intensity and less than ventilatory threshold (VT; ,70% V O 2 MAX); phase II = moderate intensity between VT and respiratory compensation point (RCP; ,90% V O 2 MAX); phase III = high intensity (.RCP)) was multiplied by exertional factors of 1, 2, and 3 respectively. Results: Multivariate analysis of variance showed that total TRIMPS for race stages 1-9 (2466 (90)) were greater than for stages 10-15 (2055 (65)) (p,0.0002). However, TRIMPS/day were less for stages 1-9 (274 (10)) than for stages 10-15 (343 (11)) (p,0.01). Despite a trend to decline, no difference in supine resting HR was found between day 0 (53.2 (1.8) beats/min), day 10 (49.0 (2.8) beats/min), and day 17 (48.0 (2.6) beats/min) (p = 0.21). Whereas no significant group mean changes in HR or HRV indices were noted during the course of the race, significant inverse Pearson product-moment correlations were observed between all HRV indices relative to total TRIMPS and TRIMPS/day accumulated in race stages 10-15. Total TRIMPS correlated with square root of mean squared differences of successive RR intervals (r = 20.93; p,0.001), standard deviation of the RR intervals (r = 20.94; p,0.001), log normalised total power (r = 20.97; p,0.001), log normalised low frequency power (r = 20.79; p,0.02), and log normalised high frequency power (r = 20.94; p,0.001). Conclusion: HRV may be strongly affected by chronic exposure to heavy exertion. Training volume and intensity are necessary to delineate the degree of these alterations.

“…Incessant SVT can result in tachycardia‐mediated cardiomyopathy 9 . This left ventricular dysfunction is usually completely reversible on control or cure of the arrhythmia 10 . SVT occasionally results in myocardial ischaemia, or precipitates cardiac failure in patients with pre‐existing coronary disease or myocardial dysfunction.…”

Supraventricular tachycardia (SVT) is a common cardiac rhythm disturbance; it usually presents with recurrent episodes of tachycardia, which often increase in frequency and severity with time. Although SVT is usually not life‐threatening, many patients suffer recurrent symptoms that have a major impact on their quality of life. The uncertain and sporadic nature of episodes of tachycardia can cause considerable anxiety — many patients curtail their lifestyle as a result, and many prefer curative treatment. SVT often terminates before presentation, and episodes may be erroneously attributed to anxiety. Sudden‐onset, rapid, regular palpitations characterise SVT and, in most patients, a diagnosis can be made with a high degree of certainty from patient history alone. Repeated attempts at electrocardiographic documentation of the arrhythmia may be unnecessary. Treatment of SVT may not be necessary when the episodes are infrequent and self‐terminating, and produce minimal symptoms. When episodes of tachycardia occur frequently, are prolonged or are associated with symptoms that affect quality of life, catheter ablation is the first choice of treatment; it is a low‐risk procedure with a high success rate. Long‐term preventive pharmacotherapy is an alternative approach in some patients.

“…7,8) Likewise, a reversibility was also observed in left ventricular dysfunction after successful RF catheter ablation of reentrant tachycardia in which AV nodal conduction block was not created. 9) However, most of the patients in these studies consisted of patients with left ventricular systolic dysfunction which improved after ablation due to different reasons. Therefore, according to these studies it is difficult to comment on the influence of myocardial damage on left ventricular function.…”

Sequential Evaluation of Left Ventricular Systolic and Diastolic Function After Radiofrequency Catheter Ablation

SUMMARYRadiofrequency (RF) catheter ablation has become standard therapy for many types of arrhythmias. RF energy may cause deterioration in left ventricular function by damaging the myocardium. The aim of the present study was to assess the changes in left ventricular function after catheter ablation using various echocardiographic parameters.Forty patients (22 women), aged 37 ± 14 years (range, 15-76 years), underwent catheter ablation for various tachycardias. Routine echocardiogaphic examination was done in all patients. Left ventricular systolic function was evaluated by the modified Simpson method and tissue Doppler. With regard to left ventricular diastolic function parameters, diastolic early (E) and late (A) transmitral filling velocities, deceleration time (DT), isovolumetric relaxation time (IVRT), and tissue Doppler parameters were assessed. All ventricular function parameters were assessed before, and 1 hour, 1 day, and 1 month after the catheter ablation procedure. To avoid any influence of heart rate on diastolic function parameters, the E/A ratio, DT, and IVRT were adjusted to heart rate (cE/A, cDT, cIVRT).No changes in left ventricular systolic function after the ablation were observed. After the ablation procedure (1 hour, 1 day, and 1 month) the cE/A ratio decreased from 1.42 ± 0.43 to 1.19 ± 0.40, 1.18 ± 0.40, and 1.30 ± 0.33 (P = 0.009), respectively. cDT increased from 210 ± 54 to 272 ± 64, 255 ± 60, 240 ± 64 (P = 0.001), respectively. Likewise cIVRT increased from 113 ± 22 to 133 ± 54, 123 ± 27, 117 ± 19 (P = 0.007), respectively. Significant changes were also observed concerning tissue Doppler parameters in assessing diastolic function.Although no significant changes were observed in systolic function after RF ablation, this procedure may have some detrimental effects on ventricular diastolic function parameters.
