Study summary

The main aim of this study, which was carried out in two parallel groups, is testing the efficacy of a specific micronutrients combination in adults with heart rhythm disturbances and accompanying symptoms.

It is therefore the investigators hypothesis that daily oral administration of the specific micronutrients combination will lead to a decrease of symptoms awareness and to a reduction of heart rhythm disturbances in adults with or without structural heart disease. The principal endpoints will be a decrease in the total score of symptoms awareness.

What researchers measure

Primary outcomes

  1. Evaluation of the changes in the perception of six symptoms

    at baseline, at follow-up visit 4 (at the end of week three) and at follow-up visit 5 (at the end of study) by visual analogue scale \[VAS\]: complete summary to a total score value in comparison to baseline

    Time frame: end week 3 and week 6

Secondary outcomes

  1. symptom awareness and responder rate

    the responder rates of the changes, measured by the amount of patients with a reduction of the total score value at follow-up visit 5 (at the end of study) in comparison to baseline of at least 20%

    Time frame: end week 6

  2. symptom awareness and changes during the study

    evaluation of the changes in the awareness of six symptoms, namely: irregular heartbeat, palpitations, heart stumbling, sweating, dyspnea, and anxiety or panic attacks at baseline, at follow-up visit 4 (at the end of week three) and at the end of week six by VAS and summary to a total score value

    Time frame: end week 3 and week 6

  3. absolute reduction in premature ventricular beat (PVB)

    the absolute reduction of the PVB in 24 hours at follow-up visit 4 (at the end of week three) and follow-up visit 5 (at the end of study) in comparison to baseline

    Time frame: end week 3 and 6 week

  4. relative reduction of the premature ventricular beat (PVB)

    the relative reduction of the PVB in 24 hours at follow-up visit 4 (at the end of week three) and follow-up visit 5 (at the end of study) in comparison to baseline

    Time frame: end week 3 and week 6

  5. responder rate of the premature ventricular beat (PVB)

    the responder rate measured by the amount of patients with a reduction of the PVB of at least 5 % at the end of study

    Time frame: end week 3 and week 6

  6. absolute reduction of supraventricular premature beats (SVPB)

    the absolute reduction of the SVPB in 24 hours in combination with a reduction of the awareness of the six symptoms

    Time frame: end week 3 and week 6

  7. relative reduction of supraventricular premature beats (SVPB)

    the relative reduction of the SVPB in 24 hours in combination with a reduction of the awareness of the six symptoms

    Time frame: end week 3 and week 6

  8. responder rate

    the responder rate, measured by the amount of patients with a reduction of the PVB of at least 5 % at the end of study

    Time frame: end week 3 and week 6
