Outcome Measures

Primary Outcomes (1)

  • Reduction in Premature Ventricular Beats

    The primary endpoint will be a 50% reduction in premature ventricular beats during 24-hour Holter monitoring after randomization to active treatment or placebo for 14 days of therapy.

    24-hour Holter Monitor after 14 days of therapy

Secondary Outcomes (4)

  • Changes in transthoracic echocardiographic parameters

    14 days of therapy

  • Frequency of palpitations

    14 days of therapy

  • Reduction of Premature Atrial Beats

    24-hour Holter Monitor after 14 days of therapy

  • Measure Temperature Rebound Rate (TRR)

    14 days of therapy

Study Arms (2)

Ranolazine

EXPERIMENTAL

Subjects will be consented by the study investigator and then randomly assigned in an allocation-concealed fashion to double blinded treatment with either titrated doses of ranolazine or matched placebo. After the initial 6 days of treatment with ranolazine, 500 mg twice daily or matched placebo, subjects will undergo repeat 24 hour electrocardiographic monitoring. If tolerated, the subjects will then have their study medication increased (Ranolazine 1,000 mg twice daily or matching placebo) with the plan to then undergo a repeat 24 hour ambulatory electrocardiographic monitoring in 6 days. When the subject returns the monitor, subjects will enter the washout period (cessation of the study medication) for 6 days and have electrocardiographic monitoring prior to return to the subject's referring provider for care.

Placebo

PLACEBO COMPARATOR

Subjects will be consented by the study investigator and then randomly assigned in an allocation-concealed fashion to double-blinded treatment with either titrated doses of ranolazine or matched placebo. After the initial 6 days of treatment with ranolazine, 500 mg twice daily or matched placebo, subjects will undergo repeat 24 hour electrocardiographic monitoring. If tolerated, the subjects will then have their study medication increased (Ranolazine 1,000 mg twice daily or matching placebo) with the plan to then undergo a repeat 24-hour ambulatory electrocardiographic monitoring in 6 days. When the subject returns the monitor, subjects will enter the washout period (cessation of the study medication) for 6 days and have electrocardiographic monitoring prior to return to the subject's referring provider for care.

  • Clinically significant hepatic disease (cirrhosis or chronic hepatitis) or abnormal liver associated enzymes greater than three times the upper limits of normal
  • A baseline corrected QT interval greater than or equal to 500msec or history of congenital channelopathy (long QT syndrome, Brugada syndrome) or torsades de pointes.
  • Treatment with agents known to prolong the QTc interval
  • Treatment with agents that are potent or moderately potent inhibitors of CYP3A, to include, but is not limited to the following: ketoconazole, HIV protease inhibitors (i.e. ritonavir), macrolide antibiotics (i.e. clarithromycin), diltiazem and verapamil
  • Females who are pregnant, planning to get pregnant, or breast feeding ( females under the age of 55 years who have not previously undergone surgical sterilization procedures will have serum qualitative pregnancy testing)
