Eligibility criteria:

        Inclusion Criteria:

          -  Healthy male or female subjects according to the assessment of the investigator, as
             based on a complete medical history including a physical examination, vital signs
             (Blood pressure (BP), Pulse rate (PR)), 12-lead Electrocardiogram (ECG), and clinical
             laboratory

          -  Age of 18 to 45 years (inclusive)

          -  Body mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive)

          -  Signed and dated written informed consent prior to admission to the study, in
             accordance with Good Clinical Practice (GCP) and local legislation

          -  Male subjects, or female subjects who meet any of the following criteria before the
             first administration of trial medication until 30 days after trial completion:

               -  Use of adequate contraception, e.g. any of the following methods plus condom:
                  implants, injectables, combined oral or vaginal contraceptives, intrauterine
                  device (in case of oral contraceptives start of contraception at least 30 days
                  before administration of trial medication)

               -  Sexually abstinent

               -  A vasectomised sexual partner (vasectomy at least 1 year prior to enrolment)

               -  Surgically sterilised (including hysterectomy)

          -  Postmenopausal, defined as at least 1 year of spontaneous amenorrhea (in questionable
             cases a blood sample with levels of FSH above 33,4 U/L and estradiol below 71,6 pmol/L
             is confirmatory) Alternatively, true abstinence is acceptable when it is in line with
             the subject's preferred and usual lifestyle. If a subject is usually not sexually
             active but becomes active, with their partner, they must comply with the contraceptive
             requirements detailed above.

        Exclusion Criteria:

             range of 45 to 90 bpm
