Methods of treating atrial arrhythmia include administering an effective amount of at least one antiarrhythmic pharmaceutical agent to a patient in need thereof, such that the at least one antiarrhythmic pharmaceutical agent first enters the heart through the pulmonary vein to the left atrium. Other methods of treating atrial arrhythmia include administering by inhalation an effective amount of at least one antiarrhythmic pharmaceutical agent to a patient in need thereof. An amount of the at least one antiarrhythmic pharmaceutical agent may peak in the coronary sinus of the heart at a time ranging from 10 seconds to 30 minutes from initiation of the administering. Unit doses, aerosols, and kits are also contemplated.

1. A method of treating atrial arrhythmia, comprising: administering to a pulmonary vein through a pulmonary tract and through use of an aerosolization device an effective amount of at least one antiarrhythmic pharmaceutical agent selected from a group consisting of class I, class II, class III, and class IV antiarrhythmics, to a patient in need thereof, wherein the effective amount of the at least one antiarrhythmic pharmaceutical agent is a total amount from 0.1 mg to 200 mg administered over multiple inhalations,wherein the aerosolization device is a nebulizer configured to administer the at least one antiarrhythmic pharmaceutical agent in a liquid pharmaceutical formulation, wherein aerosolization occurs at room temperature,wherein the at least one antiarrhythmic pharmaceutical agent level peaks in a coronary sinus of a heart of the patient at a time between 30 seconds and 20 minutes from initiation of the administering to the pulmonary vein,wherein the patient's sinus rhythm is restored to normal within 30 minutes of initiation of the administering to the pulmonary vein,wherein 1) a concentration of the at least one antiarrhythmic pharmaceutical agent in the coronary sinus of the heart is between 0.1 mg/L and 60 mg/L at 2.5 minutes after initiation of the administering to the pulmonary vein, and the concentration is less than 0.1 mg/L at 30 minutes after initiation of the administering to the pulmonary vein; or 2) 10% to 60% of a nominal dose of the at least one antiarrhythmic pharmaceutical agent reaches the coronary sinus, andwherein the method does not comprise administering an adenosine derivative. 2. The method of claim 1, wherein the concentration of the at least one antiarrhythmic pharmaceutical agent in the coronary sinus of the heart is between 0.1 mg/L and 20 mg/L at 2.5 minutes after initiation of the administering to the pulmonary vein, and the concentration is less than 0.1 mg/L at 30 minutes after initiation of the administering to the pulmonary vein. 3. The method of claim 1, wherein the administering to the pulmonary vein comprises up to 6 inhalations. 4. The method of claim 1, wherein the atrial arrhythmia comprises tachycardia. 5. The method of claim 4, wherein the tachycardia is selected from the group consisting of: supraventricular tachycardia, paroxysmal supraventricular tachycardia, atrial fibrillation, paroxysmal atrial fibrillation, acute episodes in persistent and permanent atrial fibrillation, atrial flutter, paroxysmal atrial flutter, and lone atrial fibrillation. 6. The method of claim 1, comprising administering nebulized droplets comprising the at least one antiarrhythmic pharmaceutical agent, wherein the nebulized droplets have a mass median aerodynamic diameter of less than 10 μm. 7. The method of claim 1, wherein the antiarrhythmic pharmaceutical agent is a class I antiarrhythmic. 8. The method of claim 7, wherein the class I antiarrhythmic is a class Ia, Ib, or Ic antiarrhythmic. 9. The method of claim 1, wherein the antiarrhythmic pharmaceutical agent is a class II antiarrhythmic. 10. The method of claim 9, wherein the class II antiarrhythmic is esmolol HCl. 11. The method of claim 10, wherein dosage of the esmolol HCl is between 0.5 and 0.75 mg/kg body weight. 12. The method of claim 1, wherein the antiarrhythmic pharmaceutical agent is a class IV antiarrhythmic. 13. The method of claim 12, wherein the class IV antiarrhythmic is diltiazem. 14. The method of claim 13, wherein dosage of the diltiazem is 0.25 to 0.50 mg/kg body weight. 15. The method of claim 1, wherein the at least one antiarrhythmic pharmaceutical agent level peaks in the coronary sinus of the heart at a time between 1 minute and 10 minutes. 16. The method of claim 1, wherein the at least one antiarrhythmic pharmaceutical agent is self-administered by the patient. 17. A method of treating atrial arrhythmia, comprising: administering to a pulmonary vein through a pulmonary tract and through use of an aerosolization device an effective amount of at least one antiarrhythmic pharmaceutical agent selected from a group consisting of class I, class II, class III, and class IV antiarrhythmics, to a patient in need thereof, wherein the patient self-administers and self-titrates an effective inhaled dose of the at least one antiarrhythmic pharmaceutical agent for a conversion of atrial arrhythmia to normal sinus rhythm,wherein the aerosolization device is a nebulizer configured to administer the at least one antiarrhythmic pharmaceutical agent in a liquid pharmaceutical formulation, wherein the aerosolization occurs at room temperature,wherein the at least one antiarrhythmic pharmaceutical agent level peaks in a coronary sinus of a heart of the patient at a time between 30 seconds and 20 minutes from initiation of the administering to the pulmonary vein,wherein the patient's sinus rhythm is restored to normal within 30 minutes of initiation of the administering to the pulmonary vein,wherein 1) a concentration of the at least one antiarrhythmic pharmaceutical agent in the coronary sinus of the heart is between 0.1 mg/L and 60 mg/L at 2.5 minutes after initiation of the administering the effective amount of the at least one antiarrhythmic pharmaceutical agent to the pulmonary vein, and the concentration is less than 0.1 mg/L at 30 minutes after initiation of the administering to the pulmonary vein; or 2) 10% to 60% of a nominal dose of the at least one antiarrhythmic pharmaceutical agent reaches the coronary sinus, andwherein the method does not comprise administering an adenosine derivative. 18. The method of claim 17, wherein the concentration of the at least one antiarrhythmic pharmaceutical agent in the coronary sinus of the heart is between 0.1 mg/L and 20 mg/L at 2.5 minutes after initiation of the administering to the pulmonary vein, and the concentration is less than 0.1 mg/L at 30 minutes after initiation of the administering to the pulmonary vein. 19. The method of claim 17, wherein the administering to the pulmonary vein comprises up to 6 inhalations. 20. The method of claim 1, wherein the atrial arrhythmia comprises tachycardia. 21. The method of claim 20, wherein the tachycardia is selected from the group consisting of: supraventricular tachycardia, paroxysmal supraventricular tachycardia, atrial fibrillation, paroxysmal atrial fibrillation, acute episodes in persistent and permanent atrial fibrillation, atrial flutter, paroxysmal atrial flutter, and lone atrial fibrillation. 22. The method of claim 1, comprising administering nebulized droplets comprising the at least one antiarrhythmic pharmaceutical agent, wherein the nebulized droplets have a mass median aerodynamic diameter of less than 10 μm. 23. The method of claim 1, wherein the antiarrhythmic pharmaceutical agent is a class I antiarrhythmic. 24. The method of claim 23, wherein the class I antiarrhythmic is a class Ia, Ib, or Ic antiarrhythmic. 25. The method of claim 1, wherein the antiarrhythmic pharmaceutical agent is a class II antiarrhythmic. 26. The method of claim 25, wherein the class II antiarrhythmic is esmolol HCl. 27. The method of claim 26, wherein the effective inhaled dose of the esmolol HCl is between 0.5 and 0.75 mg/kg body weight. 28. The method of claim 1, wherein the antiarrhythmic pharmaceutical agent is a class IV antiarrhythmic. 29. The method of claim 28, wherein the class IV antiarrhythmic is diltiazem. 30. The method of claim 29, wherein the effective inhaled dose of the diltiazem is 0.25 to 0.50 mg/kg body weight. 31.
