In June, 2007, I was infected with pneumonia on the train when I went home. After two weeks of treatment, the pneumonia was cured.
After another week, I always felt my heart beating wildly when I slept at night.
After a few days, I went to the hospital to do a medical test about the electrocardiogram, the doctor said that there is no problem for 100 premature beats, arrhythmia,
But I still felt uneasy, because I had never felt this way before, and always wondered if this was the beginning of something serious.
