A case study revealing how Omron monitor helped early detection of a recurring of paroxysmal atrial fibrillation.

  • Patient: 59-year-old Male
  • Major compliant: Palpitation and feeling of tightness in the chest
  • Case Presentation - Dr. Toshimichi Omae, Director of Shinurayasu Toranomon Clinic Japan & Dr.Nobuyuki Komiyama, Division of Cardiology Saitama Medical University, Japan

Situation

The patient felt tightness in his chest during a commute train ride in January 2007 and was transported to a hospital by ambulance. But, his symptoms had resolved by the time he arrived to the hospital and abnormalities could not be found.

A month later, he returned to the hospital because he feared a reoccurrence of the symptoms, which had occurred several times a year.

Monitor Outcome

The physicians leased the Omron Portable ECG monitor (HCG-801) to the patient and trained him to take his ECG when he felt symptoms. Six days later, after drinking alcohol, his heart rate raced to 166 beats per minute and he felt tightness in the chest.(Figure 1).

Because he did not have an organic disorder and his symptoms were infrequent, the patient was prescribed SunRhythm to control the symptom. He was a heavy smoker, which could increase the risk of paroxysmal atrial ?brillation, so a nicotine patch was prescribed to reduce his smoking. Since then, the symptoms have not reoccurred.

Comments from Dr. Toshimichi Omae

We have experienced many cases where symptoms have not occurred within 24 hours of using a conventional Holter monitor, especially when patient’s symptoms are infrequent. As in this case, the frequency of symptoms attained from the patient interview helped us decide to use the portable ECG monitor and the Holter monitor separately as the situation demanded, enabling us to give a more precise diagnosis.

Medical examination by portable ECG monitor is very effective for recording transient symptoms in symptomatic situations. We hope the portable ECG monitor will be used widely in medical settings to help diagnose many chest symptoms that have remained unsolved because transient symptoms in symptomatic situations can not be recorded.
