From this study (2 years ago):
Roger Gaby on Jul, 12, 2012:
Iam a 69 year-old male with a history of Mitral valve replacement and triple bypass (2008). The valve was replaced due to prolapse and atrial arrhythmia. I have been symptom free for the past 4 years (slight arrhythmia) when, after taking Tylenol Pm for sleep aid several weeks ago , I developed a tachyarrhythmia (HR over 150 BPM). After 4 days duration I saw my cardiologist who put me on a blood thinner and scheduled a visit to an EP for cardioversion. 2days after ceasing the Tylenol Pm I self cardioverted to sinus rhythm (mild arrhythmia still present) . I am a health care professional,retired Director of Regulatory Affairs at GSK and feel that I can state that the diphendramine was causal in the episode.
