Case study: Device monitors patient's ECG data after catheter ablation

A case study on how Omron ECG Device closely monitored patient's ECG data after catheter ablation at Fukuoka University Hospital, Japan.

  • Patient: 67yr old male
  • Major Complaint: Palpitation
  • Medical History:  Hypertension & Diabetes
  • Case Presenter: Dr. Kouichiro Kumagaya Division of cardiovascular disease Fukuoka University Hospital


This patient was diagnosed with paroxysmal atrial fibrillation one year ago and the frequency of his symptoms increased from several times a month to several times a week. Dr. Kumagaya prescribed several kinds of antiarrythmic drugs to the patient, but they didn’t work.

As observed above, the patient’s symptoms were frequent and serious as well as resistant to antiarrythmic drugs, so percutaneous  catheterisation was performed.

During the two week monitoring period after the operation, the patient complained of palpitation, although not too frequently. However, the ECG data was needed when the palpitation occurred, because there was a possibility of reoccurrence of the paroxysmal atrial fibrillation.

Monitor Outcome:

Since the symptoms were infrequent, Dr. Kumagaya leased the Omron HCG- 801 to the patient, who recorded his ECG when symptoms occurred. The data showed that the palpitation originated from an atrial premature beat, not from the recurrence of the atrial fibrillation.

The patient seemed relieved. He still fears a reoccurrence, so Dr. Kumagaya sometimes finds similar kinds of atrial premature beats. But atrial defibrillation has never been detected. The doctor isn’t prescribing antiarrythmic drugs and continues to monitor the patient’s symptoms.

Dr. Kumagay’s comments:

Different from traditional Holter Monitors, the portable ECG monitor can record rare symptomatic ECG waveforms. The device is easy for patients to use and with fewer required procedures. After operations, patients tend to assume arrhythmia is reoccurring if they experience symptoms like palpitation.

In this case however, we were able to record ECG waveforms in a symptomatic situation with the portable ECG following the operation.  The portable ECG monitor was useful to check that any subsequent symptoms were not a reoccurrence of the atrial fibrillation and to relieve the patient’s concerns.
