- Aim: The aim of the present study was to evaluate the occurrence of arrhythmia-related symptoms in patients with supraventricular tachycardia (SVT) referred for radiofrequency catheter ablation (RF ablation) with special focus on driving ability. Methods and Results: Of the 301 patients referred for RF ablation between November 1998 and December 2000 due to SVT 226 were active drivers. The present study is an interview study with structured questions. Hemodynamic symptoms were frequently encountered during tachycardia. The symptoms occurred irrespective of driving. In the 226 active drivers, fatigue was reported in 77%, dizziness in 47%, breaking into a cold sweat in 52%, near-syncope in 50%, and syncope in 14%. Women experienced all symptoms more frequently than men: fatigue (P < 0.05), dizziness (P < 0.01), cold sweat (P < 0.05), near-syncope (P < 0.001), and syncope (P < 0.01). Fifty-seven percent of the patients had experienced tachycardia while driving, and 42% of those patients had to stop because of it. Twenty-four of all patients considered their tachycardia as an obstacle to driving. There was a significant correlation (P < 0.001) between having experienced near-syncope and considering the risk for tachycardia as an obstacle. Conclusions: SVT frequently occurs during driving and is often associated with hemodynamic symptoms including near-syncope and syncope. Women reported tachycardia-related hemodynamic symptoms more often than men. There is a correlation between having experienced near-syncope and considering tachycardia as an obstacle to driving. The risk for serious tachycardia-related symptoms should be considered, especially in occupational drivers.

- Background: Living with paroxysmal supraventricular tachycardia affects a patient's whole life situation, but few studies have addressed health-related quality of life (HRQOL) aspects in these patients. The aim was therefore to describe HRQOL in patients with atrioventricular nodal re-entry tachycardia (AVNRT) or Wolff-Parkinson-White (WPW) syndrome, referred for radiofrequency ablation (RF-ablation), compared to age- and gender-matched Swedish reference groups. Methods: HRQOL was assessed with SF-36 and EuroQol (EQ-5D and EQ-VAS) and the patients were asked disease-specific questions. Results: The 97 patients with AVNRT [53 ± 16 years of age/65 women] and 79 patients with WPW [42 ± 15 years of age/26 women] exhibited significantly lower HRQOL scores in SF-36 in the same seven of the eight scales: Physical functioning (PF), role-physical (RP), social functioning (SF), role-emotional (RE), general health (GH), vitality (VT), and mental health (MH) while there was no difference in bodily pain (BP) compared to their respective age- and gender matched Swedish reference group. HRQOL scores were lower for patients with AVNRT compared to WPW in the areas of PF (P < 0.001), BP (P < 0.05), and GH (P < 0.01) in SF-36, and the same was found in EQ-VAS (64.8 vs. 71.2, P < 0.05). Occurrence of episodes of tachycardia more often than once a month compared to less frequently than once a month was associated with significantly lower HRQOL in all eight scales in SF-36 (GH, RE, MH: P < 0.01 and PF, RP, BP, VT, SF: P < 0.001) and EQ-5D index (P < 0.001) and EQ-VAS (P < 0.05) Arrhythmia duration longer than one hour compared to patients with shorter duration of the tachycardia-affected GH in SF-36 negatively (P < 0.05). Patients who experienced symptoms not only during activity but also at rest scored lower in SF-36 GH (P < 0.01) and SF (P < 0.05). Conclusion: Measuring HRQOL in patients with WPW or AVNRT is an important way to evaluate and describe these patients' life situation. These conditions were found to have a pronounced negative impact on HRQOL. The frequency of arrhythmia occurrence is one important factor to consider when setting priorities for treatment with RF-ablation.
